The Oyster family is Roger’s signature design – but still made to individual commission

Signature Design – ‘Oyster’

An original design

The Oyster pieces were designed to show a diamond to its full advantage. This jewellery can be made in 18 carat yellow gold, 18 carat white gold or platinum.

The photo shows Dame Judi Dench wearing the pendant and earrings in yellow gold at a New York film premiere.


The original design has round brilliant cut diamonds – the ring being tension set, the pendant and earrings channel set.

But while the Oyster collection is a signature design each piece is still made on a bespoke basis allowing for variations to suit the individual client – and of course other precious gems may be set in place of diamond.

Gem and Materials Quality

Our Gemstones are all of fine quality with diamonds supplied in grades from G VS to D Flawless – with certificates for all over a half carat. For smaller diamonds described as ‘FVS1+’ this indicates that these small stones are uncertificated but judged to be of F colour or better and VS1 clarity or better, i.e. the highest quality of small stones. The 18ct White Gold used is of a higher quality than often found in jewellery today. Only palladium rich, high white material is used to ensure the whiteness is permanent.

A Guide to prices

All pieces are bespoke-made for each client and prices would depend on the quality and size of gemstones chosen as well as on the design details.

However, as a guide, prices for the pieces photographed for this section and the gallery would range from £2,500 to £12,000 (with typical ½ ct G VS1 diamond ring at £4000).

“The ‘Oyster pendant’ is absolutely beautiful. I know that Jenny is delighted with it and we think it is a superb piece of workmanship and extremely elegant. We look forward to seeing the other items as they are produced.”
