Roseforge is a UK-based independent dealer in loose coloured gemstones, focused on two families: garnets and spinels.

The business draws on more than three decades of buying coloured stones internationally and a lifelong involvement in gems and jewellery. For the past 25 years that has included annual visits to Tucson, the world's largest gem show.

Every stone is chosen individually, hand-selected from large parcels against consistent standards rather than bought in bulk and passed along unseen. That selectivity, and a deliberate specialism, are the whole point of Roseforge.
