Diamond jewellery and loose diamonds
We buy diamond necklaces, bracelets, earrings, brooches, pendants and rings, along with loose stones removed from old mounts. Antique diamond jewellery is assessed as a whole: a Victorian star brooch or an Edwardian garland pendant has a design and a period that count in addition to the stones. Modern pieces are assessed on the diamonds, the metal and the maker. Loose diamonds of any shape are bought, certified or uncertified, including chipped stones that are suitable for recutting.
Old cut and modern cut diamonds
Diamonds cut before about 1930 look different from modern stones. Old mine cuts are cushion-shaped with a high crown and a visible culet; old European cuts are round with the same open culet; rose cuts are flat-backed and domed. They were cut by hand to be seen by candlelight, and they are bought here for what they are, not as stones to be recut. Modern round brilliants and princess, emerald, oval and pear cuts are graded on cut, colour, clarity and carat.
Certificates and what to tell us
A report from GIA, HRD, IGI, AnchorCert or another laboratory records a stone's measurements and grades, and it speeds up a valuation from photographs. Send a picture of it, with the report number visible. Where there is no certificate, the stones are graded at inspection, and the offer is confirmed then. Tell us about any earlier insurance valuation, any known treatment such as laser drilling or fracture filling, and whether a stone is laboratory grown, as each affects the assessment.

Questions about selling diamond jewellery
Do I need a GIA certificate to sell diamond jewellery?
No. We buy with or without certificates. A laboratory report is helpful because it gives measurements and grades that cannot be read from a photograph, so include it if you have one. Without a report, the diamonds are examined and graded at inspection, and the offer is confirmed at that stage.
Are old cut diamonds less desirable than modern ones?
They are different stones with their own buyers. Old mine and old European cut diamonds have larger facets, a higher crown and an open culet, and they are used in antique jewellery and in new mounts in period style. We buy them as old cuts. Describe the shape and send a face-up photograph taken in daylight.
Do you buy loose diamonds?
Yes. Loose diamonds are bought singly and in parcels, including stones taken from worn-out mounts and small diamonds from broken jewellery. Fold each stone, or each group of similar stones, in a separate paper packet and label it. Tell us the measurements in millimetres if you have a gauge, and send any certificate with the stone.
How do I photograph a diamond so that it can be valued?
Clean the piece with warm water, a drop of washing-up liquid and a soft brush, then dry it. Photograph it in daylight near a window, without flash, on a plain surface. Take one picture face up, one from the side and one beside a ruler. A short video turning the stone slowly is also useful.
Do you buy laboratory grown diamonds or treated diamonds?
Tell us at the start if you know a stone is laboratory grown, clarity enhanced or colour treated. Every stone is tested at inspection, and laboratory grown or treated stones are valued as what they are. The result is explained to you before any offer is confirmed. Jewellery set with such stones is still assessed for its mount and maker.
