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.

The World's Best Gemstone Labs

Most gems are further tested by the UK's best labs, who can use equipment such as FTIR & Raman for more detailed analysis. More valuable stones go to elite Swiss labs (that are globally renowned for coloured stone testing) or to the top US lab.

Our Gemstone Catalogue

The Gemstone Catalogue contains all our main inventory and is the perfect place to find gems for most jewellery applications. The catalogue offers an intuitive, user-friendly interface making it quick and easy to locate the stones you are looking for.

'True To Life' Gems - Online

Our industry-leading interactive 360° videos display gems in remarkable detail. Colour, clarity and cut are shown with unrivalled accuracy, and internal inclusions are clearly visible. Videos can also be downloaded and shared with end clients.

Sophisticated 'Real-Time' Stock Control

Our state-of-the-art stock management system ensures the real-time accuracy of our catalogue. Whenever a stone is sold or sent out on approval, our catalogue is immediately updated, ensuring gemstones displayed as 'IN STOCK' are available.

A Friendly, Knowledgeable Approach

Our team are delighted to use their knowledge and expertise to help clients select the perfect gems for their needs. And we have close contact with UK-based lapidaries, setters and other industry experts who can also assist our clients.
