A compact, well-proportioned grey spinel from Mogok. At 5.7 × 5.5 × 4.7mm, this 1.29ct stone has excellent depth — the 4.7mm pavilion delivers strong light return and a lively, brilliant face-up. Eye-clean clarity throughout. A practical choice for a bespoke solitaire ring where the proportions need to work well in a claw or bezel setting.

Why Grey Spinel?
Grey spinel has a refined, contemporary quality that is increasingly sought after by jewellery designers and clients who want something distinctive without being showy. The colour works in a wide range of settings and metals, and the Mogok origin adds provenance and rarity that commercial grey stones simply do not carry. Natural, untreated, and sourced directly — a stone with integrity as well as beauty.
