How to find your diamond

Use this when you already know the exact stone — for example, a stock ID a stylist sent you, or a certificate number printed on a GIA / IGI report.

Type the ID into the search field at the top of the site and press Enter. If the ID matches a single stone in our active inventory, you land directly on that stone’s detail page. No category picker, no listing.

If the ID matches nothing, the page shows the natural / lab-grown picker so you can refine the search.

For most browsing, carat is the most useful filter. Pick a stone type (Natural or Lab-Grown), then drag the carat range slider to the weight you want — say 1.00 to 1.50 ct — and combine it with shape, color, clarity, and cut.

Carat is the universal weight unit for diamonds. It does not depend on shape: a 1 ct round and a 1 ct oval weigh the same but have different millimeter dimensions.

Use this when you have a setting that needs a specific stone — a ring with a missing center stone, a pair of earrings where one needs replacing, or a bespoke design with a fixed dimension. Carat is not enough here: a 6.5 mm round and a 6 mm round can have very different carat weights, but only one of them fits the prongs.

Pick a single shape in the filter (for example Round), then a "Search by size (mm)" panel appears. The chips are not a generic chart — they are the sizes we actually have in stock right now: round goes from 4.25 mm to 13 mm in 0.25 mm steps; oval / pear / marquise show length×width pairs (7×5, 8×6, 9×7 …); cushion, princess, emerald, asscher, radiant and heart each show their own real bucket list. Tap a chip to add it; tap again to remove.

For each chip you select the system runs a tolerance cascade — first within ±0.10 mm of your size (perfect bench-fit, no head adjustment), then ±0.15 mm if nothing matched, finally ±0.20 mm as the ceiling. The result page tells you which tier produced the match so you know how snug the fit is. Cushion is treated as one shape: cushion, cushion modified and cushion brilliant variants are all included automatically — you do not need to pick three chips.

One chip on, sort = price ascending: you see the cheapest stones at the exact size you picked. Multiple chips on: the search is the OR of all chips ("any of these sizes fits") — with price ascending the smaller sizes will dominate the top of the list because smaller stones are lighter and therefore cheaper. If you want to compare like-for-like, switch to "Carat ascending" or pick one chip at a time.

Power-user shortcut: you can also type the size directly into the search bar at the top of the site. "5 mm" or "5" jumps to round 5 mm. "7x5" or "7×5" jumps to oval/pear/marquise pairs at 7×5 mm. Both run the same ±0.30 mm tolerance.

All filter sections combine with AND: shape AND color AND clarity AND mm size. Inside one section, multiple choices combine with OR: clarity VVS1 or VVS2 are both shown.

In mm-mode the carat slider is dimmed and ignored — millimeter chips already describe the size precisely, and a carat range on top would either contradict ("3 mm AND 5 ct" matches nothing) or be redundant. Switch back to carat mode if you want the slider to do anything.

If you accidentally over-filter and see no results, use the "Reset filters" button at the bottom of the panel to start fresh.
