Great product, test it with diamonds cvd mosonite , 0 fault.
The best loupe ive ever had
Great device to look at the inscription of loose diamonds and also diamond jewelry.
Much simpler to operate, can’t beat the price. Excellent tester.
I have begun using the cell on a gemmological stereo microscope, and the immersion cell sits on the 'ledge' above the adjustable iris diaphragm with a very small amount of wiggle room - this does not appear to be raising any issues. The microscope filter and Immersion cell combo is a well-constructed unit of good size which makes it more stable whilst maneuvering the gemstone with tweezers. The same can be said for adjustment the required light source/s on the gemstone and the white diffuser is easily placed under the cell. Thus, the gemstone inclusions are easier to bring into focus to observe.
I am extremely happy with this Diamond Selector Kit.
The product arrived much faster than expected.
The quality and overall presentation are absolutely beautiful and very professional.
The kit looks elegant, feels high-end and is perfect for jewelry consultations. It helps customers visualize different diamond sizes and shapes directly on the hand, which makes the consultation process much easier and more enjoyable.
I am especially impressed by the optical appearance and the high-quality execution of the entire set.
I am very glad that I decided to purchase this premium selector kit.
I also want to mention the excellent customer service.
I needed a VAT invoice for my business purchase and the team responded immediately and was very kind and helpful throughout the process.
Overall, I am very happy with my purchase and will definitely order again in the future.
Excellent product and highly recommended!
Everything was beautiful! And great service!! Thank you so much.
This is a great piece of kit, My Veritas has already paid for itself by testing over $1200 worth of purchased IGI Lab created diamonds that were proven to be Moissanite with fake certificates and have been returned for full refunds, Many thanks for the life saver GemTrue
The tool is very impressive and highly practical. It can be used to examine both rings and loose stones, including diamonds, zircons, and any round-cut gemstone. The rotating bottom disc allows for a smooth 360-degree view, which makes inspections much easier.
One suggestion for improvement would be to offer an optional ring holder attachment for examining single stones more conveniently. Another enhancement could be integrating a built-in light source, which would greatly improve visibility in low-light conditions.
The main idea behind this tool is to simplify the process of reading serial numbers and matching them with certificates. It also provides an excellent, clear view of the girdle area, making it a valuable addition to any gemologist’s toolkit.
