Unique Hand-crafted diamonds are optically, chemically, and physically identical to natural diamonds which formed billions of years ago, deep within the earth.
The modern round brilliant cut was revolutionary but remained largely unchallenged until the turn of this century.
Cut is the factor that fuels a diamond’s fire, sparkle and brilliance. A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut.
A chemically pure and structurally perfect diamond is perfectly transparent with no hue, or color. However, in reality almost no gem-sized natural diamonds are absolutely perfect.
Diamond clarity is a quality of diamonds relating to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects called blemishes.
The carat is a unit of mass equal to 200 mg (0.2 g; 0.007055 oz) and is used for measuring gemstones and pearls.
