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 rings arrived this morning - but I waited until my husband got back from Taipei to open the parcel.
I have only just opened it!
We are absolutely speechless - the ring is everything that we had ever hoped for and more. The setting is stunning and the rose gold works so well with the sapphire. The spacer ring fits perfectly too. Thank you so much for taking the time in finding us the perfect padparascha and for helping us design the ring - it is perfect, I’m so excited to wear it.
Thank you, thank you, thank you!!

We are very fortunate to have Just Gems in Winchcombe. Helen has recently rejuvenated my engagement ring with a beautiful Zircon gemstone which she took enormous effort and expertise to source the perfect replacement stone for me. I have also had a sapphire bespoke ring made which I am delighted with chosen from Helen’s large collection of coloured gemstones.All my rings are polished, sparkling and looking stunning. Absolutely recommend anyone to pop in and give Just Gems a try!
