Round Single-Cut Diamonds, SI2


Featuring a simpler-style cut, this tiny single-cut white diamond is ideal for accent stones and for repairing vintage jewelry, especially when the required stones are very small. This round diamond, graded SI2, shows noticeable inclusions that are very easy to locate under 10X magnification but is 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.

Single-cut faceting is a simpler style that features 16 facets rather than the 58 facets of a full-cut brilliant stone. This cut benefits very small stones because the fewer, larger facets increase the light reflection from the stone.
