3.47 Ct. Blue Spinel from Burma (Myanmar)

At The Natural Gemstone Company we are pleased to present a beautiful transparent 3.47 carat cushion shape blue spinel with precise dimensions of 9.42 x 8.11 x 5.35 mm. This gem is faceted in a mixed brilliant cut, a cutting style chosen to maximize both scintillation and color depth in a cushion outline. The stone exhibits dark color intensity that yields a rich, saturated blue which remains lively under varied lighting conditions. The polish is excellent, giving mirrored facet surfaces that enhance light return and contribute to the gem appearing lively and refined in finished jewelry.

Clarity is graded as very slightly included, evaluated at eye level, meaning this spinel presents minimal inclusions that do not detract from its visual appeal to most viewers and that enhance transparency and depth rather than disrupting it. The gemstone has been heat treated, a common and widely accepted enhancement for spinel that stabilizes and deepens color in a manner consistent with trade practices and consumer expectations. Origin is Burma, Myanmar, a source historically prized for producing richly colored spinels with fine crystal quality, and provenance from this region is often regarded by connoisseurs as adding to a stones desirability and market value. The mixed brilliant cut together with the excellent polish works harmoniously with the stones natural optical properties to deliver strong face up color and lively brilliance.

From a durability perspective this blue spinel is an outstanding choice for daily wear. Spinel rates about 8 on the Mohs hardness scale, which gives it strong resistance to scratches from everyday materials and makes it suitable for engagement rings, pendants, and bracelets. Spinel is isometric with no true cleavage, which contributes to good toughness and reduces the risk of splitting during routine activity. For care we recommend regular cleaning with warm soapy water and a soft brush to maintain brilliance and polish. While heat treatment for color is stable, prudent care avoiding extreme knocks and harsh chemicals will preserve both the gem and its setting. For the informed buyer seeking a combination of visual beauty, technical quality, and enduring wearability, this 3.47 carat Burmese blue spinel from The Natural Gemstone Company represents a compelling and responsible choice.
