Historic amethyst prices chart


#1

Dear Orchid:

I have read that amethyst was quite valuable at one time. Then huge
Brazilian deposits were found.

Does anyone have data on historic amethyst prices?

I do not have historical data, but it is true that amethyst was
highly desired gemstone at one time. Decline in price is not due to
Brazilian deposits, but development of lab-grown quartz which is not
easy to tell apart from natural even for gemologist. So prices
declined to the level of lab-grown material.

Hi Peter i stay in South Africa which is right next to namibia Afew
years ago I was going through the country which is very famous for
many gem stones and Diamonds and on every street corner there was a
fellow with a little parcel PSST does the boss want Amethyst There
were large 6inch long clusters of crystals as well as little plastic
medicine bottles with individual crystals They were not in very good
condition except the large clusters they were perfect but not very
purple. I BOUGHT A FEW AS WELL AS A CLUSTER FOR APPROX $15 USD
equivalent. Still got all of them about 30 crystals i was told if
they stay in the sun the color fades??? is this true mine has been
inside for 15 years now it seems the clusters have faded a bit. I
was also told they dye the quartz Crystals to look like amethyst.

fyi frank

Don’t forget treatment of other quartz gems (citrine) to produce
purple quartz
