True star sapphires are among the rarest stones in the world — the six-rayed asterism that glides across the surface is caused by microscopic rutile needles aligned deep within the crystal, a phenomenon found only in a tiny fraction of natural sapphires. The finest examples have historically come from Burma and Ceylon, prized by collectors and royalty alike for centuries. This one is a beauty: a deep blue oval cabochon measuring 8.90 x 7.20 x 3.94mm and weighing 2.63 carats, set in an ornate 18ct white gold mount with applied heart shoulders and a polished "D" profile shank, four round full-cut diamonds rub-over set to the shoulders in pairs — 0.01ct each, SI2-I1 clarity, H-I colour. Rare, natural, and professionally content appraised. EU/UK/US size 50 / K½ / 5½, weight 3.04g.

Our Vintage & Antique Jewellery

We personally select every piece, accepting fewer than 5% of items offered to us. Most are over 30 years old — many far older — each carrying its own history and character.

Very few arrive with original documentation. We assess every item using electronic testing, hallmark verification, and expert analysis. Our diamonds are earth-mined; we do not trace stone origins or treatments such as heat enhancement.

30-day return policy from the date of purchase, subject to the following:

• Items must be returned in identical condition to when sold (same weight, size, and condition)
• Refunds processed to your original payment method within 30 days of receiving the return
