Gemology

To us, it's not just a business, but a family affair where genuine academic and artistic attentiveness accompanies every item from prototyping until packaging. Matter of fact, jewellery was the natural outgrowth of our gemological endeavours. Behind our art lies a colourful and wondrous branch of science. Join our GIA-certified gemologists to the lab on a photomicrographic journey into the exotic micro-universe that human eyes can not observe in jewellery.

With our strategic location in one of the most important hubs of gems trade, an academic background and an extensive training in selection, and a direct access to miners and distributors, our gem hunters succeded at

eliminating the middleman role, reducing costs while maintaining high standards and allowing us to offer our clients a wide array of options in selection, coupled with fair and highly competitive prices.

Certification

Having academically trained and officially certified GIA gemologists in our team gives us the legal and technical ability to provide our clients with our own certification system as an optional economical guarantee of genuineness and authenticity that states the gem size, weight,  group, species, variety, possible enhancements and origin (if enough evidence was found to determine it).

 

In addition to that, we can provide our clients with certificates from the most renown and respected international gemological laboratories such as:

Where extremely sophisticated equipment can accurately screen for, and positively identify, treated and synthetic gemstones, locate origins and detect enhancements such as fracture filling, heat or laser treatments using high power magnification and a combination of results from the Diamond Sure™, Diamond View™, Raman Spectroscopy, FTIR (Fourier Transform Infra-Red), UV-Vis (ultraviolet-Visible Spectrophotometry) and XRF (X-ray Fluorescence). Such certificates take about 2-6 weeks to perform (depending on the lab) and are also available upon client request.
