Jewelers loupe is a loupe designed for jewelry. It must generate a view that is clean, clear, crisp, contrast, sharp, no fringing color (color-corrected), and most importantly no distortion (no blur). It also provides a sufficient wide of view that makes the eyes comfortable to focus on.
It’s a handheld tool. There is the cover that is used as the handle as well. Also, it is built portable in order to easily carry around.
Unlike other loupes such as a dental loupe, this kind of loupe must be positioned near the workpiece. In other words, the focal length is short. You need to move it back and forth to get the exact focus. Also, it provides 10X magnification as the standard. But you could find them 20X, 30X, and 40X magnified.
Whether the lens is made of glass or polycarbonate, the material quality and the design are much more affecting. We see that the triplet design is capable to bring a sharper view. Moreover, the Anti-Reflective coating applied to the lens can provide more contrast results. Certainly, the design and lens quality induce to the price.
Although it sounds made for jewelers, in fact, it’s used by various professions such as gemologists, horologists, engineers, coin collectors, stamp collectors, biologists, geologists, and the likes. Whoever the users, it’s a very quick and useful tool to grab when you are going to inspect a small object.
On this page, you’ll find an article that discusses the best loupe for jewelry along with its buying guidance and other basic information. Keep reading for further information such as what is the factors that make a loupe able to use for jewelry louping, what is aplanatic and achromatic, etc.

Top 10 Best Jewelers Loupe Reviews
1. Zeiss D40-10x Professional Jewelers Loupe
Zeiss D40-10X loupe is the star. It gives a superior view quality for the users. This is the best jewelers loupe for diamonds due to its view quality that is sharp, color-corrected for sure, contrast, and totally no blur.
This pocket-size loupe is perfect for the professionals. It uses a standard 10X lens, that makes the inspection a lot easy.
Another feature is the AR (Anti-Reflective) coating that aims to get a more contrast view. The coating prevents light reflection, absorbs the light, and results in smaller light lost. You’ll never find glare on the surface because the light is refracted by almost 99.5%.
The only drawbacks are the small lens (13mm diameter) and no eyelet. For some users, the small-diameter lens might be unpleasant to their eyes. And the lack of eyelet could make the loupe lose. If you are looking for a quality loupe like this one that comes with a wider lens, the price might rise significantly.
- The lens is made of glass
- 13 mm lens diameter
- 10X magnification
- Field of view is 22 mm

2. Nikon Triplet Jeweler Loupe
The same with Zeis 40D-10X above, this Nikon loupe also provides an excellent view of the object being identified. Its triplet design generates a color-corrected and blur-free result. The view is seriously sharp from edge to edge.
However, compared to Zeiss, Nikon has no AR (Anti Reflection) coating that means less contrast than Zeiss. But it has an eyelet to let your lanyard tied through it. Another drawback is the small lens diameter (13mm). Some people may not be used to this size.

3. Belomo 10x Triplet Loupe for Jewelry
Belomo 10x triplet loupe is a good option if you are looking for an affordable one. As we found on the market, this one is so much popular due to its wide field of view, price point, and decent quality.
This one is actually a triplet loupe, but not as good as Zeiss and Nikon. In comparison with Zeiss and Nikon above, you could still find a little blurred area around the edges. However, compared to other cheap non-triplet loupes, this one is definitely much better. The view generated by Belomo loupe is free from chromatic aberration. You’ll not any fringing color at the boundaries of the view.
Another benefit of this made-in Belarus loupe is its wide diameter. You’ll not find it too small. So, the field of view is quite big and comfortable for your eyes. To sum up, we suggest this loupe for coins, gemstone, rocks, and the likes. This Belomo loupe doesn’t come with a lanyard except for this series.
- 10X magnification
- AR Coating
- Glass lens
- 21mm diameter lens
4. Ade Advanced Optics 10x21TB-A Decent Triplet Loupes
This one is the competitor of Belomo due to the quality that comes with a nearly similar price point. It’s a triplet lens, 10X magnification, wide field of vision (19mm diameter lens) that would make your eyes need less force to view the object, clear, and sharp like Belomo. If you are looking for some decent jewelers loupes for inspecting rocks and gemstone, this should be the one.
The things that set it apart are the field of view or distortion area. Both of these two things are caused by the aplanatic quality of the lens. In short, Ade loupe has a slightly wider field of view than Belomo 1oX loupe. As a result, the distortion area is also improved. However, in comparison with the cheap ones, you are lucky to find this item. Another thing is it doesn’t come with a lanyard. But, as you could see, the lanyard eyelet is available there.
- 10X magnification
- 19mm lens diameter
- Glass lens
- Leather case
5. Bausch & Lomb USA Made Triplet Jewelers Loupe
This Bausch & Lomb loupe is great not only for jewelry but also for coins. Its magnification is smaller than the average of jewelers loupe magnification which is 7 times but because of that magnification, its field of view is getting improved. So, that is great for coins.
We find this loupe the only one loupe that is made in the USA, Rochester NY to be exact. Sure, it becomes American pride. The lens design, which is triplet, will correct the color and prevent spherical aberration that commonly happens to a single lens. This one is good for inspecting the jewelry such as diamond but we are not sure it could magnify the laser inscription number. Perhaps, you have to reconsider this one for that purpose.
- 7X magnification
- 20mm lens diameter
- Made in the USA
6. SE Professional Quality LED Light Triplet Loupe
It comes with 6 built-in LED bulbs inside the loupe. The 6 LEDs are distanced equally apart from one another circumferencing the loupe to create the perfect lighting. It’s expected to create a shadow-free condition to the area being lighted.
This 10X triplet loupe should be decent for reading the GIA/AGS certificate number, especially because of the nice lighting. The lens diameter is also wide which is cozy for eyes. But if you could afford the higher magnification one, that would be better.
There is another SE Pro loupe series that comes with UV light (SE Professional MJ37802LV). The UV light will be very useful to identify the security feature in currency. It’s also reactive to Fluorite and Sodalite. That means it’s an al loupe for minerals.

7. Schneider L2 Achromatic Aplanatic Triplet Professional Jeweler’s Loupe
If you are looking for a true professional jewelers loupe for diamonds, that will fully provide a sharp view from edge to edge, color-corrected, and will not strain your eyes, then we highly encourage this one. Although it is expensive, this one will save you from making a mistake that could cost a lot of money.
It’s made in Germany by famous Harald Scheider. The triplet lens is made of high-quality “glass” that will make it fully achromatic (no fringing color) and aplanatic (sharp/no distortion). Moreover, the 20mm lens diameter will create a wider field of view and keep your eyes relief longer from fatigue during the viewing. Therefore, what makes this one obviously different than Zeiss and Nikon is the diameter lens. It’s wider and as a result, your eyes are healthier using it.
This standard 10X magnification Schneider L2 triplet loupe has the previous series of Schneider L1. By comparison, Schneider L2’s lens is thinner (14mm) than the L1 (18mm). This is due to the thin anti-reflective coating of L2. However, the thin Anti Reflection coating does make it able to reflect the purple color on the lens and becomes lighter.
Whether you are a grader, seller, or buyer; it’s encouraged to purchase this one. Don’t miss out on any inclusion that might not visible by others, that could lose you a lot of money or generate you more money. In addition, it comes with the lanyard to hang it around your neck plus the leather case for initial protection from dust and water.

8. Fancii LED Jewelers Loupe for Coins
Fancii FC-LP20XW loupe is the best jeweler loupe for coins. In case you need to magnify flat objects, we suggest this one. It’s not like the other hand loupe, this one is stationary. So, you need to put the workpiece on a surface and take the view. Nicely, this state will allow you to take the picture with your smartphone.
Is this tripet? Not sure if we see from the pictures shared by the buyers. There seems a significant distortion around the edges. It should be more clear if it’s triplet. However, in case you are going to read the laser inscription number of a diamond, it should be okay due to the 20X magnifying rate glass lens and its bright 6 LED lights spread evenly around the edges. You just need to put the diamond at the right angle so that it’s readable.
Because it uses LED lights, the battery is needed. It uses three LR927 batteries. Whenever you work in less lighting, you can turn it on. Turn it off vice versa.
- 20X magnification power
- 6 LED lights
9. Jarlink 30X 60X Illuminated Jewelers Loupe
This loupe is not triplet but you’ll shockingly see its view quality. At the first time of reviewing, we didn’t find any sign of a triplet label on the product. But soon we saw many buyers found it work for jewelers.
It provides two lenses. The first bigger one is 30 times magnification, while the smaller one is 60 times magnification. The LED features on each lens are useful to view in dim light, especially the smaller lens that may block ambient light. It only needs an LR1130 battery which is considered easy to find in the store.

- LED light
10. Qooltek Headband Strap Jewelry Makers Loupe
It comes with a frame like the glasses frame. So, your hands now can fully focus on the object viewed. Don’t worry it will fall down, you can use the strap (headband) to hold on the loupe tightly.
No matter how dominant your right or left eye. The loupe can be adjusted so that there is only one loupe that is used. Simply, push up one loupe while the next loupe is left to be used. Never use the pair, it will not work.
Here is the most important thing. It comes with 8 substitutional lenses (2.5X, 4X, 6X, 8X, 10X, 15X, 20X, and 25X) that bring different magnification for each (ranges from 0.5 to 6.2 inch). Therefore, we would recommend this for jeweler makers. Also, since the 10X lens is available and its focal point is 1.4″, it seems suitable for inspecting diamond (jewelry). However, we are not sure it’s triplet-constructed. From the customer reviews, we didn’t find any statement this is a triplet. So, you could rethink before buying this for inspecting diamond.
Another nice feature is the LED lights which are designed and positioned beside the lens. It can be adjusted so that the light focus can be directed exactly to the workpiece. You will find it very useful when working in dim light.
- 2.5X, 4X, 6X, 8X, 10X, 15X, 20X, and 25X magnification

What is Jewelers Loupe?
As the name suggests, this sort of loupe is used for jewelry. Whether to inspect or make jewelry, it functions to magnify the piece so we can view them in detail sharply. People also use this loupe to view the rocks, minerals, watch, etc.
Jewelry refers to personal ornaments that are made of or contain commonly these: diamonds, gemstone (ruby, sapphire, etc), precious metal (gold, silver, etc), and pearl. But, the most common use of a jewelers loupe is for diamonds and gemstone.
Jewelers Loupe for Diamonds
To inspect a diamond, you’ll assess these 4 things (4C): Cut, Color, Clarity, and Carat. You’ll use light to inspect the cut to see how sparkling it is. The color can be assessed by a trained eye. And the carat, you’ll rely on a diamond weight scale. When it comes to clarity, you’ll use a loupe.
The clarity itself consists of blemishes and inclusion. Blemishes are the flaws located on the surface. While the inclusion is the flaws located in the internal body of the diamond. Both of them determine the grade of the diamond. The less the clarity, the higher the grade. And the higher the grade, the more expensive it is.
Suppose you are going to buy a diamond ring from someone. She said it’s a true FL diamond. But, your loupe evidently finds a bearding (a type of inclusions). Imagine if your loupe fails to provide a good view and you miss out on the bearding. You lose thousands of dollars.
Aside from inspecting the clarity, it is also needed to read the small inscription GIA/AGS certificate number which is engraved microscopically. These numbers are invisible to see by the naked eye. It can be only spotted by a loupe.
Furthermore, a certain diamond (1 carat or weigher) comes with a clarity plot. It will tell you exactly where the inclusions and blemishes are on the diamond. By means of a jewelers loupe, you could match up the inclusions and blemishes that are mapped at the plot to the real inclusion you are viewing.
Jewelers Loupe for Gemstone
Basically, the jewelry loupe for gemstone has the same tasks. It’s used to view the external surface, cabochons, inclusion, and coloring of the gemstone. However, since gemstones are available in various colors and the need to provide better color quality is critical.
Moreover, both loupes for gemstone and diamonds are designed to have a short focal point of about one inch. So, you need to put the piece close to the loupe as well as your eyes also being so.
Therefore, A Jewelers Loupe Must be …
In short, a jewelers loupe must be at least: 1). Aplanatic and 2). Achromatic. And this quality can be achieved from the fixed lens construction that is called triplet.
Aplanatic loupe is simply a no blur loupe. The view generated by the loupe is clear, sharp, crisp, and no distortion can be seen around the edges of the loupe.
The distortion or blur is caused by the phenomenon called spherical aberration.
If you find a sharp view at the center of a loupe but the edge area is blurred, then it’s a phenomenon of spherical aberration. To understand how that could happen, the following video could explain it clearly.
Both aplanatic and achromatic loupe makes the view become distortion-free. However, the type of distortion fixed by the achromatic loupe is the distortion caused by the fringing color.
That fringing color happens due to the phenomenon called chromatic aberration. The boundary of an object becomes colored. It could be red, blue, or green. Even it could be the mixing of those three colors. In some cases, it also could be purple or pink.
There are countless examples of chromatic aberration on the web. You could google for “chromatic aberration examples” terms to see exactly how it looks like.
Buying Guide of the Loupe for Jewelry
There are three types of loupe based on loupe construction: singlet, doublet, and triplet. As the name suggests, the singlet is a single loupe. The doublet is two loupes. And the triplet is three loupes. The loupes are joints together using a certain technology.
The doublet loupe has a better view than singlet but the triplet is the best. Why? Because the triplet model will correct the color and provide a less blur view. The problems that always happen to a singlet loupe are the spherical and chromatic aberration. So, the triplet is the very well construction preferred to see details on gemstones and diamonds.
The standard magnification of a loupe for jewelry is 10X. It’s considered as the most comfortable magnifying ratio. There are also 20X, 30X, and 40X magnification loupes for jewelry available, but the diameter lens generally becomes smaller.
Magnification and field of view are two unseparated things. The higher the magnification, the smaller the field of view. The smaller the field of view, then you have to move the loupe very slowly and carefully. Your eyes also have to work hard. It could lead to eye fatigue and even further make you suffer a headache.
To read the laser inscription, a higher magnification loupe should work better. We also suggest using additional lighting. The laser inscription contains some letters and numbers that represent the certificate number of the diamond. This code must be the same as the code on the certificate. In case you have sent it to get repaired, you could know it’s yours or not by checking the certificate numbers.
3. Lens Diameter
Some people would find that 10X loupe with lens diameter bigger than 16mm is relaxing to their eyes. But they generally have distortion at the edges at least a little. Then improved by the same 10X magnification but the lens diameter becomes smaller. Therefore, if you find a jewelers loupe with high-quality 10X vision, totally sharp from edge to edge, plus features wide lens diameter, it’s unsurprisingly expensive.
A sufficient source of light is necessary to contribute to providing a clear view. Whenever you are working in a less bright place, you need an illuminated loupe to light the piece. A simple LED loupe is sufficient for that.
This is a kind of rope that is tied on the loupe so that you can hang it around your neck. The main function of this feature is to keep the loupe from losing. Not all loupes come with a lanyard, but they generally provide an eyelet to let you make your own lanyard and tie the lanyard there.
Investing more budget to pick up a high-quality loupe will not waste your money. It would help you avoid making hundreds of dollar mistake. The above list contains our favorites. You could carefully read the entire list to find out your pick. However, if you ask us to narrow them, we will recommend these three loupes.
Well, here it is. When the price doesn’t matter, Schneider L2 is our recommendation. It’s for highly jewelry professionals. Surely, it’s a triplet lens, comes anti-reflecting coating to avoid color loss, 20mm lens diameter (wide diameter), and eyelet.
If you are trying to best possible quality at a lower price, then Zeiss D40 is our recommendation. It’s a triplet-constructed loupe and provides AR coating. But, you have to struggle a little with its smaller lens diameter. Overall, the quality of Zeiss jewelers loupe is mesmerizing.
Lastly, if you are on a budget, then Belomo would be a great pick. There is only a small portion of distortion around the edges.
