4.42 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 4.42 carat oval blue sapphire measures 10.04 x 8.44 x 6.15 mm, and presents a mixed brilliant cut that combines a faceting scheme designed to maximize both brilliance and depth. The mixed brilliant cut uses a brilliant facet arrangement on the crown and a modified pavilion to return light with lively scintillation, producing a dynamic play between sparkle and saturation. Clarity is graded as very very slightly included evaluated at eye level, which for an educated buyer means inclusions are minimal and do not detract from visual performance when set, contributing to a clean face up appearance. The color intensity is vivid, with a saturated blue that shows depth without appearing overly dark, and the polish is excellent, which helps deliver crisp facet junctions and optimal light return. These attributes together yield a sapphire that displays strong presence and refined optical performance under both natural daylight and warm indoor lighting.

This sapphire is from Ceylon, Sri Lanka, a historic source known for producing blue sapphires with lively, vivid hues and fine clarity, and provenance from this region is a valued attribute among collectors and connoisseurs. The stone has been heat treated, which is a stable and widely accepted enhancement used to improve color uniformity and reduce the appearance of minute inclusions, and this treatment is disclosed transparently to ensure informed purchase decisions. From a gemological perspective, the primary value drivers for this sapphire are its vivid hue, substantial carat weight, attractive proportions for an oval, and the very very slightly included clarity grade evaluated at eye level, combined with excellent polish and a skilled mixed brilliant cutting approach. As corundum, sapphire offers high durability for everyday wear, ranking next to diamond in hardness, and the combination of quality factors here positions the stone as a meaningful acquisition for a collector or a client seeking a signature center stone.

When set in jewelry this vivid blue sapphire will complement a wide range of skin tones, and understanding undertone interaction will help in selecting metals and mounting styles. On fair and cool undertones the blue reads as crisp and slightly more electric, and settings in white metals such as platinum or 18 karat white gold will enhance the cool clarity of the blue while maintaining a modern, restrained aesthetic. For warm undertones and richer complexions the vivid blue benefits from juxtaposition with yellow gold, which introduces a warm contrast that makes the blue appear slightly more saturated and regal. Olive skin tones often carry both warm and cool elements, and a neutral metal selection such as pale rose gold or a two tone mounting can harmonize the blue while allowing its vividness to remain central. For deeper skin tones the sapphire’s vivid color provides a striking, luminous focal point, and a bezel or low profile prong setting will offer both presence and comfort, letting the color sing against the skin. Adding a diamond halo or accent stones will increase perceived size and brilliance for clients who desire added sparkle, while a solitaire bezel or classic prong setting emphasizes color purity and clean lines.
