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.

“Mr D writes…
“Just Gems” came recommended by a friend who knew the owner Helen Plum personally.
I have now visited the shop on four occasions and have been treated so nicely and helpfully on every occasion.
I don’t know much about jewellery, and I was advised and informed patiently, and without pressure.
I have now bought two items for my wife - an opal pendant and a pair of south sea pearl ear rings.
The quality of the stones is clear, and the workmanship is excellent, and my wife has been delighted (and wants more!!)
I shall look no further than “Just Gems” when buying my jewellery in the future - cannot recommend enough.
“Miss M writes…
I just wanted to say a big thank you for all your help and expertise in creating my beautiful engagement ring. It is better than I ever imagined….just stunning! I have not stopped admiring it since my fiancé and I collected it from your shop.
