The Just Gems Shop
27 North Street, Winchcombe, Gloucestershire
The shop has a wide selection of carefully sourced unmounted gems. If you would like to choose a loose gem in any size, shade or cut, we have a large number of suitable stones just waiting for you! Our gems are collected from personal contacts of Helen Plumb, relationships she has developed over more than twenty years of working with the international gemmological trade. Wherever possible, our stones are ethically sourced and many come from known mines in Brazil, Afghanistan, East Africa, Sri Lanka and elsewhere.
We also love pearls at Just Gems, and offer a matching service to make up earrings, bracelets, pendants or necklaces that will enhance your own pearl jewellery. We restring pearls in our workshop and can replace or repair damaged clasps. Please note that we only mount natural gemstones and restring real pearls (cultured or natural) and gemstones. We do not work with simulants.

The ring arrived safely, gosh it is lovely. I wore it on Saturday night and a lady in the restaurant at an opposite table could not stop staring at my sparkly finger.
“Mrs B writes…
I cannot thank you enough for coming to talk to our Parents’ Association last night and for giving us such an interesting and fun evening. Everyone who came has raved about how fascinating your talk was and how much they enjoyed themselves and many who could not make it, hearing reports, would like us to organize it again!
