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.

From our customers…

Mrs G writes…

You made Pearl and Sapphire earrings for my daughter’s Graduation and restrung Pearls. She is delighted with them and they suit her perfectly. She also came first in her year in Geology at Glasgow so they were very well deserved!

Mrs P writes…

I have worn my ring several times now and am enjoying it so much. You have designed it so well and it fits very nicely with my wedding ring. You were so patient as I took my time in deciding which of your stones I preferred, and I not feel any pressure to make a decision. I am so pleased you are displaying it on your website, it deserves no less. I was wearing it this morning and my hairdresser exclaimed ‘What a really beautiful ring’, and it is just that!
