1.53 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This unheated, transparent blue sapphire from Ceylon, Sri Lanka weighs 1.53 carat and measures 7.67 x 5.66 x 4.37 millimeters, presenting an elegant oval silhouette with a mixed brilliant cut and an excellent polish. The stone exhibits intense color intensity and a clarity described as very slightly included when evaluated at eye level, characteristics that allow for strong color saturation and visual depth while retaining accessibility for close inspection. Free from enhancement, the sapphire offers a natural presentation prized by connoisseurs and jewellers alike, and its combination of transparency, cut, and finish makes it a versatile center stone for high quality, enduring pieces.

The proportions and mixed brilliant facet arrangement provide lively scintillation and a balanced face up appearance, qualities that translate well into a variety of mounting styles. As a centre stone for an engagement ring it adapts to four or six prong settings, including traditional upright orientation or an east-west placement for a contemporary profile. A low bezel or half bezel can be specified to increase security and everyday wearability, while a halo of melee diamonds or complementary sapphires will amplify perceived size and color presence without obscuring the clarity and natural saturation. The oval form also lends itself to three-stone compositions, split shank designs, cluster settings, pendant focal points, solitaire studs in bespoke ear settings, and custom cocktail rings where the balance of brilliance and hue is essential.

When specifying metal and complementary gems, this sapphire pairs well with platinum for a monochrome, modern elegance, with 18 karat white gold for bright contrast, and with yellow or rose gold where warmth enhances the blue tones. Its 1.53 carat weight and near eight by six millimeter dimensions make it suitable for medium to substantial finger sizes, and it can be set to sit low for daily wear or mounted higher to increase presence. The Natural Sapphire Company can provide setting recommendations, accurate CAD previews, and bespoke design services to realize a design that respects the sapphire’s natural attributes, functional requirements, and the client’s aesthetic preferences.
