The sunny color and round brilliant cut of this treated yellow diamond makes it an ideal choice for adding a pop of color to high-end jewelry designs. Use it to embellish earrings or pendants, or pair it with any color or size of diamond to create more complex matched sets, including rings and bracelets. The stone may contain characteristics of both SI1 and SI2. It shows small, possibly noticeable inclusions visible under 10X magnification and will be eye-clean when oriented face up. Diamond is the birthstone for 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.
