Treated Black Diamonds Round


Description

This treated black diamond features a round brilliant cut and offers a bold accent to high-end designs—it looks great in contrast with white diamonds. Set it in a simple mounting by itself, or pair it with any color or size of faceted stone or cabochon to create a pendant, ring, or bracelet. Diamond is the birthstone of April.

Composed only of carbon and shaped by eons of incredible heat and pressure, diamond is the hardest gemstone known to man and are sought after as the stone of choice for engagement rings, anniversary gifts and congratulatory gifts for graduation, promotion and other milestone accomplishments. When properly cut, diamond generates a high dispersion of light, creating the "fire" of color for which the stone is so treasured. Diamonds occur in nature in a variety of colors including red, green, yellow, blue and black; however, it is the clear, colorless gem that remains the most popular in jewelry. According to legend, diamond is the combination of all gems, "pure as a dewdrop and invincible." Folklore holds that it is the symbol of perfection and illumination, enhancing second sight and stimulating ingenuity.

The classic and most popular cut for diamonds, the round brilliant cut is a 58-facet cut with facets divided among the crown, girdle and pavilion. The number and arrangement of the facets is precisely calibrated to achieve maximum light dispersion.
