7.32 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 7.32 carat cushion shape blue sapphire measures 10.97 x 8.99 x 7.62 mm, and presents a vivid, saturated blue that is immediately striking. Cut as a mixed brilliant, this stone marries the scintillation and fire of brilliant style facets with the depth and richness that a cushion outline provides. The cut proportions are well balanced, producing a lively face up appearance while preserving sufficient depth to maintain color saturation, and the excellent polish ensures crisp facet junctions and a bright surface finish. Evaluated at eye level, the clarity is described as very very slightly included, which means that the stone is essentially clean to the unaided eye and retains outstanding transparency, and with no enhancement reported this sapphire is completely natural and untreated. Origin is Ceylon, Sri Lanka, a source renowned for producing sapphires with lively, vivid blue hues, and this provenance contributes meaningfully to the gem's desirability among educated buyers.

The mixed brilliant cut used on this cushion sapphire enhances both brilliance and color performance, with a well cut crown that returns light efficiently, and a pavilion design that deepens the blue without creating dead zones. The dimensions of 10.97 by 8.99 mm provide an ideal table size for ring applications while the 7.62 mm depth gives the stone optical weight and presence. Very very slightly included clarity evaluated at eye level indicates that any inclusions are minor and do not interrupt the flow of color or light. Under magnification small needle or crystal inclusions that are characteristic of natural corundum may be visible, and these inclusions actually serve as confirmation of natural origin, as opposed to lab created material. The excellent polish contributes to surface durability and maximizes light return, so the stone will perform exceptionally in any well designed setting.

On the Mohs scale of mineral hardness this sapphire rates as 9, and that is the practical point of reference for durability. Diamonds are harder at 10, but no common jewelry gemstone approaches the toughness and scratch resistance of sapphire except diamond, and this places sapphire well above popular gemstones such as topaz at 8, and quartz at 7. For daily wear applications this hardness makes a sapphire an outstanding choice for engagement rings and frequently worn pieces, though hardness does not equal immunity to breakage from sharp blows or chipping along facet junctions. Given the 7.62 mm depth and the robust nature of this stone, both prong and bezel mountings are excellent options, with bezel settings offering additional protection for corners and edges in active wear scenarios. Cleaning is straightforward, use warm water, mild detergent, and a soft brush, and while untreated sapphires are generally more tolerant of ultrasonic cleaners than heavily included or filled stones, we recommend consulting with a jeweler prior to using ultrasonic or steam cleaners to preserve long term integrity.

At The Natural Sapphire Company we place particular value on untreated, vividly colored Ceylon sapphires, and this 7.32 carat cushion presents a rare combination of size, color, clarity, and natural origin. The absence of enhancement increases rarity and market desirability, and for a collector or a client seeking a long term wearable investment the stone represents an excellent balance of beauty and durability. We recommend an independent gemological report for collectors who require formal documentation of origin and treatment status, and we are pleased to assist with bespoke mounting options, certified appraisals, and secure consignment or purchase arrangements.
