2.79 Ct. Blue Star Sapphire from Burma (Myanmar)

This gemstone is a translucent 2.79 carat oval shape blue star sapphire, precisely measured at 8.01 x 7.00 x 4.45 mm, presented in a traditional cabochon cut with an elegantly domed profile. The gem displays light color intensity within a cool to medium blue hue, and it is graded as very slightly included when evaluated at eye level. The polish is excellent, and the surface shows no signs of wheel marks or abrasion, contributing to a clean face up and an even reflectance across the dome. Enhancement is absent, the stone is natural and untreated, and the origin is Burma Myanmar, a source historically associated with superior material and fine silk inclusions. These core technical parameters define both the aesthetic presence and the investment potential of this star sapphire, and they explain how the piece delivers a balanced presentation between body color clarity and asterism under direct illumination.

The star effect is a result of oriented rutile silk inclusions aligned within the corundum lattice, and in this specimen the asterism is centrally located and responsive to a point light source. The cabochon cut is executed with consideration for the crystal axis orientation, the lapidary having centered the dome over the rutile alignment to produce a precise star that moves predictably as the light source is shifted. Dome height and profile are technical variables that directly influence star sharpness and contrast, and with a height of 4.45 mm on an 8.01 mm length the dome presents a strong curvature that optimizes internal reflection for a clear star image. The translucency allows enough light transmission for a three dimensional star appearance without losing body color, and the excellent polish ensures minimal surface scattering so the asterism reads crisply in standard viewing conditions.

Clarity grade described as very slightly included at eye level indicates that inclusions are present but not disruptive to the gem’s overall performance or viewer enjoyment, and when examined under magnification they reveal the fine silk responsible for the asterism rather than detrimental fractures. The light color intensity provides a delicate, classic blue that balances a pleasing face up appearance with the need for contrast against the star. From a gemological perspective the combination of light body color and well developed asterism is desirable because heavier color can sometimes mute the star while lighter tones can diminish perceived depth. The excellent polish and symmetrical oval outline contribute to an efficient face up size for a 2.79 carat stone, enabling both comfortable wearable proportions and a visually broad table that highlights the interplay between body color and star. The measurements guarantee predictable results when set, allowing for precise mounting tolerances and optimized viewing from typical wearable angles.

Origin and treatment history are central to valuation and collecting considerations, and this sapphire’s Burmese provenance is significant. Burma Myanmar has produced some of the most sought after star sapphires because of the unique combination of silk quality and corundum crystal habit, and an untreated example from that region carries an elevated market position among connoisseurs and investors. The absence of enhancement confirms that the star, color, and clarity are all natural features, which supports long term desirability and resale strength. At 2.79 carats this stone occupies a sweet spot where it is large enough to make a statement without the scarcity premiums that apply to much larger material, and the oval cabochon silhouette lends itself to both classic and modern settings, increasing its utility for bespoke designs while preserving collectible value.

Owning this gem through The Natural Sapphire Company is an acquisition of both aesthetic distinction and technical craftsmanship, as the piece exemplifies deliberate lapidary choices paired with natural material rarity. The star sapphire functions as a wearable work of gemological engineering, with the domed cabochon cut aligned to the corundum axis, a carefully balanced body color optimized for asterism visibility, and an unaltered internal silk network that produces a stable and attractive star. For the knowledgeable buyer this represents an investment in documented provenance, precise craftsmanship, and natural gem properties that age well over time. We recommend viewing the sapphire under a point light source to appreciate the centered asterism, and consulting with our specialists at The Natural Sapphire Company for mounting options that protect the dome and maximize the star in daily wear. Proper care involves avoiding high heat and abrasive chemical exposure, and a protective setting that prevents edge knocks will preserve polish and polish luster, ensuring this Burmese star sapphire remains a prized and enduring asset.
