Round brilliant diamonds graded Excellent for cut — the top grade a diamond can receive, and the one that determines how much light a stone returns to the eye. Cut matters more to a diamond's appearance than colour or clarity, and it's the only one of the 4Cs decided entirely by the cutter rather than nature.
Every stone here is natural, independently certified, and physically in our Sydney office — not a virtual listing from someone else's inventory. Prices are wholesale, because you're buying from the importer rather than a retailer.
Choose your diamond first, then the setting. Many of our ring designs take a stone straight in, or we design and make a ring around it. If the size, colour or clarity you want isn't here, we source it and bring it in for you.
Excellent cut grades apply to round brilliants only. For fancy shapes, cut quality is assessed differently — talk to us and we'll walk you through it.
