Congratulations! You have found a Morganite gemstone! Blue Morganite is the pretty, peachy-pink variety of beryl, cousin to more familiar beryls like emerald and aquamarine.
Morganite is also known as "pink beryl", "rose beryl", and "pink emerald". Orange/yellow varieties of Morganite can also be found, and color banding is common.
Morganite was first discovered in California in the early 20th century and soon thereafter in Madagascar. Though there are also small deposits in Brazil, Mozambique, Namibia, Afghanistan, and Russia, quality Morganite remains relatively rare.
Morganite's good hardness of 7.5 to 8 on the Mohs scale is the reason for its excellent wearing qualities.
