Quality. Transparency. Efficiency.

Sustainable Supply Chain

Our business starts with securing the very best gemstones from the most established and trusted sources. We have excellent partnerships with top suppliers at source who can offer us a consistent and reliable supply of the finest quality stones.

Gemmologists With Real Experience

Before a stone is included in our stock, it is thoroughly evaluated by an approved Gemmologist from our panel. All our Gemmologists have FGA (Gem-A) or GG (GIA) qualifications & at least 10 years of practical gemmological experience.

Advanced Equipment - In House

Our team test every single gemstone with highly advanced equipment (that is usually only used by top labs) such as 100x gemmological microscopes and Fourier Transform Infrared (FTIR) spectroscopy machines, that we have in house.

The World's Best Gemstone Labs

Most gems are then further tested by trusted labs, who can use the full range of advanced equiptment for detailed analysis. High value gemstones go to the elite Swiss labs (that are globally renowned for coloured stone testing) or to the top US lab.
