Bangkok Blue Sapphire (Neelam) 6.03 Carat — Certified Premium Oval Mix Cut
This Bangkok Blue Sapphire (Neelam) 6.03 Carat (6.63 Ratti) is a natural, lab-certified sapphire featuring a rich blue colour and an elegant oval mix cut. With an impressive face-up size of 11.1 × 8.7 mm and a depth of 6.5 mm, it delivers strong finger coverage and a premium statement look when set in a ring or pendant.
Bangkok is globally known as a major sapphire trading and cutting hub. This gemstone is heated and treated, a permanent and widely accepted industry-standard enhancement used to improve colour and clarity while preserving the stone’s natural corundum structure.

Why This 6.03 Carat Neelam Stands Out
Natural Blue Sapphires in the 6+ carat range are less common in the certified gemstone market, making this a strong option for buyers looking for a rare size with excellent presence. The oval shape enhances spread on the finger, while the mix cut adds brilliance and lively light return — an exclusive choice for premium jewellery and traditional preferences.
