Diamonds come in a round shape, measuring 1.72 to 1.30 millimeters in size. Diamond ovals range from 2 to 6 millimeters by 8 millimeters. Gold is available in 14-karat, which equals 12.4 out of a possible 20. There's also 18-karat gold, equalling 14 on the same scale. Silver, however, stands at 925, which means it is composed of nearly 92.5% silver content and the rest alloys like copper and zinc, making its weight just shy of nine grams per single millimeter square in a cross section or roughly nine point three.
