My sister lives in Arizona so I have seen a lot of turquoise jewelry on my visits there. Much of this is Indian turquoise that is sold either on the reservations or in boutique shops.
How can the average person know if they are buying chalk turquoise or something that is of a higher quality?
I like to make a lot of my own jewelry and have seen yellow turquoise beads sold on some online websites. My understanding this is called yellow turquoise because it is mined in the same mines as the blue/green mineral, but is a combination of jasper and quartz stones.
The yellow turquoise beads are pretty and work well with certain colors, but nothing beats the exquisite look of turquoise.
