0.60 Ct. Bluish Green Sapphire from Madagascar

As a gemstone specialist with The Natural Sapphire Company, I am pleased to present a beautifully transparent 0.60 carat round bluish green sapphire, presented in a classic round shape with precise dimensions of 4.87 by 4.83 by 3.48 mm. The gem is cut to a mixed brilliant style, which combines a brilliant faceted crown with a faceted pavilion designed to enhance both sparkle and color depth. At 0.60 carat this sapphire sits in a desirable weight class for both everyday jewelry and investment pieces, offering a proportional presence that reads as substantial on a finger yet remains versatile for many mounting styles. The intense color intensity of this stone is immediately evident, a balanced bluish green that shows depth and saturation without appearing overly dark, and the excellent polish ensures that light flows across each facet cleanly, maximizing both brilliance and the perceptible clarity of the gem.

Clarity has been graded as very very slightly included when evaluated at eye level, an important distinction for educated buyers. In practical terms this means that any internal characteristics are minimal and do not detract from the gem when viewed without magnification, so the sapphire appears essentially eye clean. This level of clarity is significant because it preserves transparency and light return, allowing the mixed brilliant cut to perform optimally. The mixed brilliant cut itself is a technical choice that balances scintillation and color saturation. The broader crown facets disperse light to create lively scintillation on movement, while the pavilion geometry channels depth to emphasize the bluish green hue. The gem depth relative to its average diameter is approximately 72 percent, a proportion that contributes to the gem showing strong color without becoming overly windowed or excessively dark. The excellent polish, combined with careful facet symmetry, means that contrast and facet crispness are maintained across the surface, which is especially important in stones with intense color where facet definition affects perceived saturation.

The origin of this sapphire is Madagascar, a source that has become increasingly respected among connoisseurs for producing sapphires with vibrant and unusual color ranges, particularly in the teal and bluish green families. Madagascar stones often form in metamorphic environments that impart complex trace element chemistry, which can yield the compelling bluish green tones present in this gem. Equally important for discerning buyers is the enhancement history. This sapphire is reported as having no enhancement, meaning the color and clarity are entirely natural and untreated. Untreated sapphires, especially those with intense natural color and strong clarity, occupy a premium segment of the market because they represent rarity and natural formation conditions that cannot be recreated through heat or diffusion treatments. From a long term perspective this factor contributes to both aesthetic and market value, since untreated gems with attractive color profiles are preferred by collectors and those seeking to preserve provenance and authenticity.

From a practical and advisory perspective, a 0.60 carat round sapphire of this quality offers multiple advantages. Its weight and dimensions make it an excellent choice for fine jewelry designs where balanced proportions are desired, and where the stone should read as substantial without overwhelming a setting. For an engagement ring or a special piece, the mixed brilliant cut will deliver lively scintillation under varied lighting conditions, while the intense bluish green color will maintain presence both in daylight and under incandescent light. The gem is durable for daily wear, reflecting the hardness of corundum, and the very very slightly included clarity supports stability while allowing impressive transparency. At The Natural Sapphire Company we can provide further services including high resolution imagery, viewing under different lighting, and independent laboratory reporting upon request, to assist with appraisal and certification. If you would like recommendations for mounting styles, I can suggest settings that best showcase color saturation and protect the stone while allowing maximum light interaction, and I remain available to discuss this sapphire in detail and to arrange private viewing or purchase.
