When people buy at true rates, they can sell jewellery at true rates too.

We do not just show stones. We help small jewellers build a point of view, a product and a confident customer conversation.

Explore the families we work with. Every conversation is shaped around the stone, the setting and the person it is meant to become.
Earth formed, individually rare.
Natural diamonds carry a geological history written deep within the earth. We help you understand that history through the four Cs, proportion, provenance and the certificate beside the stone.
Science made, beautifully precise.
Lab grown diamonds are real diamonds created in a controlled setting. CVD uses a carbon rich chamber where the stone grows layer by layer. HPHT recreates the intense pressure and heat that forms diamonds below the earth. Both are graded to the same standards as natural stones.
Colour with a point of view.
Coloured diamonds bring a different language to a collection. We guide you through natural colour, treated colour and lab grown colour with the same care given to every stone.

Rate guide
Understanding how diamond pricing works.
The same stone can carry very different price tags depending on where it is bought. Understanding these three layers helps you judge whether an offer is genuinely fair.
01
Wholesale Pricing
Rates apply when diamonds move directly from a source like ours to jewellers, retailers or informed buyers, with minimal markup layered on top. This is the closest a buyer can get to a stone's true trading value.
02
Bulk Pricing
When a buyer commits to a larger quantity, whether a matching set or a mixed parcel, the per stone cost typically comes down further. This suits jewellers building regular inventory.
03
Retail Pricing
What most consumers see in a showroom. It generally includes several layers of markup for distribution, overheads and margin, stacked on top of the diamond's underlying wholesale value.

We are a sounding board, not just a supplier.
Small jewellers deserve access to good counsel. We help you choose with your customer, your craft and your long term reputation in mind, sourcing at honest wholesale rates and explaining the reasoning behind every recommendation. That is how our mission travels beyond one stone.
