The Just Gems Shop
27 North Street, Winchcombe, GloucestershireThe 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.

Why do I go to Just Gems when there are other Jewellers in town? Many reasons, first and foremost Helen is very knowledgable and enthusiastic about Gems.
Her shop is a lovely place to visit. She has many unique stones and pieces of jewellery. Helen is very willing to help you choose a piece of jewellery or a unique gem from her large selection. She will help you design and have made a personal piece of jewellery.
I have had a beautiful Black Opal and Sapphire ring specially designed by her, it has been much admired.
I can thoroughly recommend her if you wish to have a unique piece of Jewellery.

I opened my 50th birthday present in the company of very good friends and there was a gasp, I was completely over whelmed it was exactly as I had always dreamed of. Since I’ve been wearing the ring I can not take my eyes off it, it’s just so incredibly sparkly and the setting is beautiful, it looks stunning on my finger. It certainly catches the attention of complete strangers! I love the fact that it has a personal engraving inside which means so much to us both , it makes it extra special.
