Spessartite garnet briolettes on 20k gold chain (briolette=teardrop shape)
spssartite garnet: Spessartine is a manganese-aluminum garnet; the manganese gives it the orange colors that fine spessartines are prized for (although they can range from a brilliant yellow-orange to a dark red-orange). They are typically included with fine small crystals or bubbles. These inclusions are referred to as “sugar” and can give the garnet a soft glow in the hand that is difficult to capture in a photo. The gems are rarely very large, particularly in the finest orange colors but they are very brilliant due to a high refractive index of 1.789 to 1.820 as well as a relatively high dispersion value of 0.027. With a Mohs hardness of 7-7.5, its a durable gemstone.
Found mainly in Africa now, but historically found in the Hercules Mine and the Little Three Mine in California.
