Hi, I just happened across your site while getting ideas for my wire wrap gemstones and sea glass.

The fact that you give away information, don’t insist personal information, has bought my business already.

To add to the joy (yes, I’m prone to hyperbole but I’m absolutely enchanted with your business model), you add stone treatment information rather than burying it somewhere.

It’s very important to me to be able to tell my customers the what’s been done to their stones, the quality, source and composition of the gems they buy.

I believe I’m the only vendor to have the FCC and AGIA disclosure booklets available at any festival I’ve attended.

You have a customer now and, if OK, I will use your page on stone treatments, with proper attribution of course, as a handout at my next festival the end of this month.

Brightest blessings,

Turquoise Comparison


... is what I have turquoise? A list of stones often called turquoise in the trade. Some are and many are not. If you have any questions about the gemstone you have and whether or not it is turquoise, take a look at the pictures and see if you can identify the bead you have.

Turquoise comparison chart

Top to bottom

1. Many colors of dyed magnesite
2. Magnesite dyed blue
3. Turquoise jasper
4. Magnesite white with brown lines
5. Howlite, notice the grey matrix
6. Block turquoise
7. Hubei green turquoise clear stabilized, natural color
8. Carico Lake turquoise
9. Sleeping Beauty turquoise
10. Kingman Arizona, clear stabilized
11. Australian turquoise
12. Fox turquoise

To put all of this in perspective, 10 strands of the howlite or magnesite can be purchased for what a strand of the North American turquoise would normally cost.

There are other colors out there right now, everything from purple to pink to yellow to red to mosiacs. I personally know of two producers in Arizona that makes some of these products from stabilized and color shot low grade material. There very well may be other producers I am not aware of. Most of all I see on the market and at bead shows is dyed magnesite or something similar.
