Natural African Blue Sapphire (Neelam) — 9.99 Carat (10.98 Ratti)
Photos: This SKU has side, back, and in-hand views — there is no separate close-up / macro photo in this set. Use all three together to judge colour, polish, depth, and size.
This listing is a natural African blue sapphire (Neelam) of 9.99 carat (10.98 ratti), cut in an oval faceted style with a deep blue look face-up. Origin: African. Ratna Gems sells it as authentic corundum, Un-Heated & Un-Treated, with no glass filling for enhancement. Many blue sapphires sold through Bangkok-type channels are heat-treated for better colour; some low-grade stones in the trade also get filling or other tricks. This stone is offered for buyers who want that step up in natural quality — for fine jewellery or personal / traditional use.
Blue sapphire is blue corundum (Al2O3). It rates 9 on the Mohs scale, so it wears well in jewellery if the mount protects edges and corners. Typical R.I. is about 1.762–1.770 and specific gravity about 4.00. Trace iron and titanium give the blue colour. You may notice pleochroism (different shades when you tilt the stone) — often greenish-blue and violetish-blue in blue sapphire.
Inclusions: Natural sapphires can show fine rutile “silk,” small crystals, or colour bands. These are often only clear under magnification; without a dedicated macro shot, rely on the side and back views and your identification report for detail.
Gem identification report included with your order.

Setting ideas
At 9.99 carat, this oval is a large statement — ideal as a ring or pendant. White or yellow gold and silver-toned mounts all work. A bezel or half-bezel can help protect the girdle on a daily-wear ring. Share the side photo with your jeweler for basket height.
Tradition note
Some people wear Neelam for Saturn (Shani) reasons. That is personal belief, not something we promise. For birth-chart advice, speak to an astrologer you trust.
