7.40 Ct. Grey Sapphire from Burma (Myanmar)

This is a fine example of a slice shape grey sapphire weighing 7.40 carat with dimensions of 12.68 by 9.95 by 4.19 millimeters, presented in a tablet cut and exhibiting semi translucent character. The stone shows an intense color intensity and an excellent polish, and its clarity grade is slightly included, evaluated at eye level. There is no enhancement of any kind, and the origin is Burma Myanmar. The tablet cut preserves the natural hexagonal growth pattern that is visible from the top of the slice, and this growth structure gives the piece both a distinctive appearance and a direct visual connection to the crystal as it formed in the earth.

From a grading perspective the clarity description slightly included, evaluated at eye level, means that there are internal features that can be seen without magnification under normal viewing conditions, yet these inclusions do not overwhelm the gem or significantly reduce its appeal. Inclusions in sapphires are often composed of mineral crystals, needle like rutile or silk, and growth zoning, and in a semi translucent tablet cut these features become part of the character of the gem. The intense color intensity in a grey sapphire is an important attribute because grey tones can range from washed out to strongly saturated, and an intense grey will show depth and complexity, especially when combined with the layered growth rings apparent in this piece. The excellent polish maximizes the reflection of light from the tablet surface, giving the stone a smooth tactile feel and enhancing its visual presence despite the semi translucent body.

The fact that this sapphire has no enhancement significantly strengthens its value proposition for an educated buyer. Common treatments for corundum include heat treatment to improve color and clarity, diffusion processes to alter color near the surface, and fracture filling to mask cavities. An unenhanced sapphire from Burma Myanmar carries provenance that is historically prized for corundum and suggests natural color and clarity attributes that have not been artificially altered. Burma Myanmar has produced some of the most sought after sapphires and rubies, and while supply is variable the provenance adds a layer of desirability among collectors and connoisseurs. A 7.40 carat slice that retains visible natural growth features and shows intense color without treatment is comparatively rare and appeals to buyers who prioritize natural origin and minimal intervention.

For practical use this sapphire is robust and suitable for a variety of jewelry types because corundum rates 9 on the Mohs hardness scale, offering excellent resistance to scratching for daily wear. The tablet slice format is particularly striking in bespoke designs that celebrate the natural geometry of the stone, and recommended settings include bezel or custom gallery mounts that protect the stone edges while showcasing the layered growth structure, or a pendant design where the semi translucent quality can interact with transmitted light. At The Natural Sapphire Company we emphasize transparent information about origin treatment and grading, and we can provide further detailed imagery, angles, and discussion of mounting options to help you evaluate how this stone will perform in a finished setting. If desired we can also arrange independent laboratory documentation to accompany the sapphire so you have formal verification of the attributes described.
