7.11 x 5.07 x 3.16mm natural medium-red Andesine Labradorite in oval checkerboard shape. This gemstone is from Congo and has a finished weight of 0.64ct. The clarity of this Andesine Labradorite is VVS, which stands for "Very, Very Slightly Included" seen under 10 x magnification. Surface diffusion has been applied to this gemstone; it is a safe treatment and only used to improve its appearance. The item is sold as seen in the picture: 1 piece red Andesine Labradorite for the price listed.
VVS is one of the best clarity gradings available. This gemstone is graded VVS.
The gemstone comes in calibrated size of 7 X 5 mm which is preferred for standard-sized jewelry settings.
This is a good size for a center-stone in a ring design.
My only consideration for this particular purchase is that it is from a lot and I don't get to select the specific gem I want. However, I trust GemSelect and they all look good in the picture provided and are all the same approx. size and weight. My only real concern is the star in the star ruby, as I want one that is both clear and shapely.

Diffusion treatment involves heating a gemstone with one or more chemicals. Surface diffusion affects mainly the surface of the gem, while lattice diffusion penetrates the crystal lattice. Many star sapphires are diffusion treated with rutile to improve the star. More about treatments
