2.30ct marquise cut Burmese red ruby BIANCO gemstone. This particular piece is from the original BIANCO gemstone collection, circa early 1980's, as featured in the very first Robb Report Magazines, published by Robert L. White. Bianco® is a trademark that many consider to be synonymous with "the best of the best." Bianco-Diamonds® are not to be confused with a Zircon, with Moissanite by Charles Colvard, simulated Moissanite, simulated Cubic Zirconia or a Crystal. Bianco-Creation-Gemstones® and Bianco-Diamonds® are unique man-made, hand-cut, creations that have been hand selected for their beauty, comparable to the finest geologically mined gemstones. Bianco stones have extraordinary properties - specific gravity between 5.6 and 6.0 (1.6 times that of an uncut diamond), a high refractive index at 2.15â2.18, a dispersion of 0.058â0.066 using the same grading scale as a geological carbon diamond. White diamonds fall within a color chart of colorless A-C, near colorless-F, faint yellow G-N up to "SZ" which is yellow. This stone, if graded using a geological diamond grading system, would be classified as VVSI-E, virtually flawless. At your request, your gem comes with a certificate of authenticity and lifetime guarantee from breaking or chipping. Bianco-Creation-Gemstones® have been purchased, for over three decades by the sophisticated, elite, and celebrity buyers. Before you buy, learn more about Bianco gemstones at: www.bianco-diamonds.com
