Hi, Its natural moonstone All right, The best blue moonstones in the
world come from the mines in Mittiyagoda in Southern Sri Lanka. As a
fellow Orchidian very rightly said they don’t come large sizes most
pieces are the size of Quarters.
Moonstones come in may shades and characteristics , peach , cats eye
, Blue , Rainbow and many more , All are natural ( Not too sure if
they are making synthetics now ) but most are fairly inexpensive .
I Do have a few samples of LARGE and Small Stones Please see
