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.
