Rare, Natural, Untreated High-Quality Spinel—Sourced Directly from Mogok, Myanmar, with No Middlemen. A Timeless Gem Formed Over Millions of Years. Trade Enquiries Welcome.
Independent lab reports & certificates available at buyer's cost.
A 0.85ct natural untreated blue sapphire from Mogok, Myanmar — untreated with slight inclusions. A well-proportioned stone at 5.2 × 4.6mm with a confirmed Mogok origin and no heat treatment. At this size and price range, untreated Mogok blue sapphire offers excellent value against comparably sized heated stones from lesser origins.
Sub-1ct untreated Mogok blue sapphire represents an accessible entry point into a genuinely premium material category. Sapphire is the hardest of the commonly set coloured gemstones at 9 on the Mohs scale — harder than spinel, tourmaline, and aquamarine — which makes it one of the most practical choices for everyday jewellery use. Untreated natural blue with a Mogok provenance at this size is suitable for earring studs, pendants, and smaller ring commissions where the treatment status and origin matter to the end customer.
We specialise in natural untreated spinel, sourced directly from small-scale miners in Mogok, Myanmar — one of the world's most celebrated gem origins. Gemstones are hand-cut locally. All gemstones are available for private viewing across London at your business premises or by appointment at Hatton Garden.
