3.58 Ct. Blue Sapphire from Burma (Myanmar)

This is a GIA certified natural blue sapphire from Burma, weighing 3.58 carats, in a classic oval shape with dimensions of 10.50 by 8.52 by 4.55 millimeters, and a mixed brilliant cut. The stone also has a GRS certificate confirming that it is unheated and a natural GRS-type "royal blue" sapphire. The gem exhibits a vivid color intensity and an excellent polish, and it is eye clean when examined at typical viewing distance. There has been no enhancement, which means this stone is untreated and in its natural state, a feature that carries particular importance for collectors and connoisseurs. The GIA report provides independent verification of identity and key properties, and the documented origin from Myanmar situates this sapphire among the most historically revered sources of blue corundum. The Natural Sapphire Company offers this sapphire with full laboratory documentation, which adds a layer of transparency and provenance that discerning buyers require.

From a grading and cutting perspective, this sapphire demonstrates attributes that intelligent buyers evaluate closely. The clarity grade of eye clean indicates that inclusions do not interfere with the visual experience under unaided eye examination, a meaningful distinction because many sapphires of similar color contain visible silk or crystal inclusions that soften the face up effect. The mixed brilliant cut blends step and brilliant facets to balance color saturation with scintillation, so the gem presents deep, saturated blue in the face up view while returning lively flashes of light as it moves. The proportions are well considered, with a depth of approximately four point five five millimeters and a depth ratio near forty eight percent, a range that preserves a generous face up area while avoiding excessive windowing or a closed appearance. The excellent polish further refines light return and surface brilliance, and the dimensions and weight make this sapphire versatile for high end rings, pendants, or bespoke settings where both presence and refinement matter.

In comparing this stone to famous sapphires in history, the reference points are instructive rather than literal. Kashmir sapphires are celebrated for a velvety, cornflower to royal blue tone resulting from specific trace element balances and unique crystal structure, and while those examples are exceptionally rare, this untreated Burmese sapphire shares the deep, saturated hue that collectors prize. Burmese sapphires from historic Mogok deposits are renowned for intense, pure blue and a glassy transparency, and this gem exemplifies that tradition at a size and clarity level that remains uncommon. Large museum pieces like the Logan Sapphire and the Star of India are historically significant for their size and narrative, but they often differ in origin, treatment history, or optical character. The value of this gem resides in the combination of untreated status, vivid color intensity, eye clean clarity, and a refined mixed brilliant cut, which together create an aesthetic and investment profile more closely aligned with elite, historically famous blue sapphires than with run of the mill commercial material.

For an educated buyer evaluating rarity and long term value, several factors make this sapphire compelling. Untreated Burmese stones of this size and with this level of face up color and clarity are scarce in the market, and the GIA certification from The Natural Sapphire Company facilitates confident acquisition, resale, and appraisal. The three point five eight carat weight and the oval outline produce an attractive spread on the finger without compromising depth, and the mixed brilliant cutting style enhances both color saturation and lively scintillation. From a design perspective, this sapphire will perform beautifully as a center stone in a classic solitaire or halo setting, or as the focal point of a custom piece where the gem can be oriented to maximize color and brilliance. Care is straightforward, using gentle cleaning and avoiding thermal shock or harsh chemicals, and periodic professional inspections will preserve polish and setting security. If provenance, untreated natural origin, and a balance of color intensity and eye clean clarity are priorities, this Burmese blue sapphire offered by The Natural Sapphire Company represents a rare opportunity to own a stone with both aesthetic resonance and credible, documented value.
