Lab-created stones
Several months are set with lab-created stones. A lab-created stone has the same chemical makeup and the same hardness as the mined version, and is grown rather than dug. It is graded and cut the same way, and it is marked as lab-created wherever it appears so you always know which you are buying.
Buying for someone else
If you are not sure of the month, the stones above are chosen just as often for their color. Pieces that take a birthstone list every stone available for that design on its product page.
