Design & Price Your Ring

Our settings are sold on their own so you can choose your centre diamond separately. Set the 4Cs below to see what that stone should cost, then add a setting for your full ring budget.

Diamond Shape

Round costs the most per carat — it loses the most rough in cutting. Fancy shapes give you more size for the same budget.

Carat Weight

Price climbs faster than weight, and jumps at the round numbers — 0.90ct costs noticeably less than 1.00ct for a difference nobody can see.

Colour

D–F are colourless, G–J near colourless. Once a stone is set in gold, most people cannot tell G from D — which is where the value sits.

Clarity

VS1 and above are eye-clean at arm's length. Paying up to FL buys a certificate, not a visible difference.

Cut

The one grade worth paying for — cut is what makes a diamond return light. We do not recommend going below Very Good.

Questions About Pricing

Does the setting price include the centre diamond?
No. Our settings are sold on their own so you can choose your centre diamond separately. The carat weight listed on a setting is the total weight of its accent diamonds, not the centre stone.
Why does a round diamond cost more than a fancy shape?
A round brilliant loses more of the rough stone during cutting than shapes like oval, emerald or princess. At the same carat weight and grades, a fancy shape is typically less expensive, which is why it gives you more visible size for the same budget.
Is this estimate a final quote?
No. Centre diamond figures are market estimates for lab-grown stones and will vary with the individual stone and its grading report. Setting prices shown are our real current prices. Contact a specialist for a firm quote on a specific stone.
