testimonials

Excellent service, fast responses, product delivered as expected. Have bought items multiple times and very happy with services. Communications are exceptional.

Alison Russel

Highly professional with some really exceptional products for those who work on jewelry or precious stones, I’ll gladly come back to purchase a tester for mounted CVD stones in the future. I purchased the Gemtrue Veritas from them, it works 100%, tested on many stones and they give the exact outcome.

The microscope filter and Immersion cell combo

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.

Excellent quality, beautiful presentation and great customer service

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!
