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.

It’s a beautiful ring and I love it, thank you. The colour does shine out as promised and the size is good. What a gorgeous tourmaline!

Mrs K writes…

Morning Helen - I took delivery of my rings yesterday. I just can’t believe that my Grandmother’s ring is the same one - it looks absolutely stunning! I hadn’t realised it had all those diamonds in it and the sapphire is such a beautiful shade of blue and all the work that has been done is excellent - thank you so much! My opal ring look identical and to my untrained eye I can’t tell the difference between the original stone and the new one, its like having an old friend back! The previous stone certainly took a whack looking at the crack on it! Anyway thank you once again, regards
