Andrew Grima pieces we have bought and sold, photographed by us.
Andrew Grima in brief
Andrew Grima (1921 to 2007) trained as an engineer and came to jewellery after the war, through his father-in-law's London firm, H.J. Company. There he began making gold look as though nature had made it: cast from twigs and bark, textured, and set with uncut crystals and large coloured stones chosen for their colour and shape, with diamonds used as accents. The 1961 International Exhibition of Modern Jewellery at Goldsmiths' Hall marked the turning point, and through the 1960s he won the Duke of Edinburgh's Prize for Elegant Design and a run of De Beers Diamonds International Awards. He opened his shop on Jermyn Street in 1966 and was granted a Royal Warrant in 1970. After leaving London in the 1980s he worked in Lugano and Gstaad, and his wife Jojo and daughter Francesca continue the name.
The Grima pieces we buy
- Brooches and pendants. Textured gold set with tourmaline, citrine, aquamarine, amethyst, rutilated quartz, opals, pearls and uncut crystals.
- Rings. Cocktail rings with large coloured stones and crystals.
- Earrings, bracelets and necklaces.
- Cufflinks in textured gold.
- About Time watches and other Grima watches.
- Pieces from the named collections, such as Rock Revival, Supershells, Sticks and Stones and A Tale of Tahiti.
- Pieces in their original Grima cases.
A piece we have handled
We have bought and sold Grima ourselves, including a pair of 18KT yellow and white gold textured abstract clip-on earrings, the two colours of gold worked into the bark-like surface that is typical of his London work.
Reading the marks on a Grima piece
This is where Grima differs most from the other houses on our site, and where owners most often need help. Grima pieces made in Britain are signed GRIMA and carry a full British hallmark, and the sponsor's mark inside the hallmark tells you which period the piece comes from:
- HJCo: H.J. Company, the family firm, used until about 1971.
- AG Ltd: Andrew Grima Limited, from about 1971.
- TES: used for Grima by the goldsmith Tom Scott from the late 1980s to the late 1990s.
Pieces made in Switzerland from the mid-1980s are signed GRIMA and marked 750, without British hallmarks, because they were not assayed in Britain. On later pieces the enclosed parts of the R and the A in the GRIMA signature are filled in, as in the logo.
One mark to be careful of: a G inside a circle is the mark of Philip Grima, a different maker. It is similar to, but not the same as, Andrew Grima's signature. And jewellery Grima made for other European houses was sometimes unsigned and marked later by the retailer.
How we check Grima
- The signature and sponsor's mark
read with the hallmark as above.
- The date letter
which should agree with the sponsor's mark and the style of the piece.
- The goldwork
Grima texture is deliberate and varied, and the back of a piece is finished with the same care as the front. Later imitations of the style tend to be thinner and more uniform.
- The stones
We identify every stone, including crystals and rough material. For stones without a laboratory certificate, our figures are careful estimates, not laboratory certified.
- Boxes and papers
Any box, certificate or receipt is checked against the piece itself: models, serial numbers and dates should agree.
What we look at when valuing Grima
- The design and period, read from the marks.
- The stones: what they are, their size and colour, and their condition.
- The goldwork and its condition, including dents, repairs and lost texture.
- Provenance: the original case, receipts, exhibition history or a family story about how it was bought.
We do not publish prices. Every Grima piece is valued individually from your photographs, free.
Free, no obligation, returned at our cost if you decline.

Questions about selling Andrew Grima
Where is the best place to sell Andrew Grima jewellery in the UK?
Choose a buyer who reads Grima's sponsor's marks and values provenance, not the gold alone. Mozeris buys Grima directly: a free valuation from photographs, then an appointment in Mayfair, London, or Braintree, Essex, Special Delivery post or free collection from home. You are paid the same day after inspection.
Do you buy second hand Andrew Grima?
Yes. Almost all the Grima we buy is pre-owned or inherited: brooches, rings, pendants, earrings, cufflinks and About Time watches. Grima jewelry bought abroad, including Swiss-made pieces, sells to us in the same way. Photograph the signature and the sponsor's mark.
Do you buy signed Grima pieces and About Time watches?
Yes. We buy signed Grima brooches, rings, pendants, earrings and cufflinks, and the About Time watches made with Omega, along with other Grima watches with stone or crystal dials. Please photograph the piece, the GRIMA signature and the hallmark, and for a watch the dial, case and bracelet.
How do you authenticate and date Andrew Grima?
We read the GRIMA signature and the sponsor's mark: HJCo until about 1971, AG Ltd from then, TES in the late 1980s and 1990s. The London date letter gives the year. Swiss-made pieces from the mid-1980s carry GRIMA and 750 without British hallmarks. A G inside a circle is Philip Grima, a different maker.
Does provenance affect the valuation?
Yes. With Grima, a piece's history matters. An original Grima case, a receipt from the Jermyn Street shop, exhibition or publication records, or a clear family account of when and where it was bought all help us place a piece and support its value. Send photographs of any paperwork with the piece.
Can I sell Grima without the box or papers?
Yes. Grima pieces are signed and, when British-made, hallmarked, so we identify and date them from the piece itself. Most of the Grima we see has no paperwork. If you have the original case, receipts or any history of the piece, please send photographs, as they add to its story.
What is the resale value of my Grima?
Resale value depends on the design and period, the stones and crystals, the goldwork and its condition, and any provenance. We do not publish figures. We are a direct buyer, not a pawnbroker: you sell outright, with no loan to repay. Send photographs for a free valuation, subject to inspection.
How quickly are you paid?
You are paid the same day after inspection, once you accept our offer, by bank transfer or in cash. At a Mayfair or Braintree appointment that is during your visit. Pieces posted or collected by FedEx are inspected when they arrive, and payment is made that day. If you decline, we return the piece at our cost.
Do you buy 1960s and 1970s Grima?
Yes. Most of the Grima we see dates from the 1960s and 1970s, when he worked from London: textured gold set with tourmaline, citrine, aquamarine, amethyst and uncut crystals, and named collections such as Rock Revival and Supershells. Pieces with damage or old repairs are welcome too; please do not repair or polish them first.
