0.67 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire presents as a transparent 0.67 carat round, with precise dimensions of 5.14 x 5.08 x 3.41 mm, cut as a mixed brilliant to optimize both scintillation and depth, the crown displaying classic brilliant facet geometry for lively light return, the pavilion executed with modified facets to deepen tone and center the eye into the stone. The total depth of 3.41 mm corresponds to an approximate depth proportion of 66.7 percent relative to the mean diameter, a proportion that enhances the vivid color intensity while maintaining strong return, the finish is an excellent polish delivering crisp facet junctions and minimal surface disturbance under loupe inspection. Clarity is graded as very slightly included when evaluated at eye level, inclusions are small and well positioned so as not to interrupt the optical performance, the vivid color intensity is notable for pure blue saturation with minimal secondary hues, and the origin is Ceylon, Sri Lanka, with a standard and stable heat treatment recorded to enhance clarity and color stability consistent with responsible lapidary practice. The Natural Sapphire Company presents this gem with full documentation of treatment, origin, and measured dimensions for clients seeking technical certainty.

For custom settings the mixed brilliant faceting and vivid Ceylon blue recommend contrasting accent choices and metal selections that highlight both brilliance and hue, a halo of full cut melee diamonds in F to G color and VS to SI clarity will increase perceived size and add bright white scintillation without overwhelming the sapphire, single cut or rose cut diamond accents may be used selectively along the gallery to preserve a vintage aesthetic while maintaining sparkle. Metal choices of platinum or 18 karat white gold will maximize perceived whiteness and cool contrast, bringing out the pure blue, while 18 karat yellow or rose gold will create a warm contrast that emphasizes the stone darker tones and deepens visual saturation. For color harmony pairings consider small Ceylon or Kashmir tone sapphires for a monochromatic composition, or use pairs of tsavorite garnets or mint tourmalines to provide a cool complementary green contrast for a modern cluster design. For everyday wear a low bezel or secure four prong setting will protect the girdle and preserve the mixed brilliant face up performance, for high drama a cathedral setting with a diamond halo and tapered baguette shoulders will emphasize table presence and optical depth while retaining the natural character that defines this Ceylon sapphire from The Natural Sapphire Company.
