Help can anyone tell me what sark stone is I have seen two
pieces one was definitely amethyst and the other looks like
purple glass.
“Amethyst was formerly obtained in the Island of Sark in the
Channel Islands was sold as ‘Sark Stones’. the deposit is now
exhausted and ‘Sark Stones’ sold to tourist is material from
Brazil.”
from the book “GEMS THEIR SOURCES,DESCRIPTIONS AND
IDENTIFICATION” by R.Webster, page 184.
