Not all turquoise is equal in value or collectibility; most turquoise sold in the U.S. today is from China, has been dyed and stabilized. Nothing wrong with that, as long as the customer is paying accordingly. For collectors (and fans) of American Southwest jewelry, there are still a few mines in operation, such as the Kingman mine. Colors vary by nature. Carolyn Pollack has--for some jewelry designs--used turquoise from a specific, new vein at the Kingman mine that's a bright, true teal or turquoise hue. This ring being one example. There's very light veining in the ring I received, it's beautifully cut and polished, and sits securely in a hefty amount of sterling silver in a simple, elegant design that's very flattering on the finger. All measurements stated on the product page are true, and sizing appears to be very true to size. The ring is comfortable as well. Classy!

All Carolyn Pollack pieces are made in the U.S.A. of recycled sterling silver. This ring, using a stone from an American mine, shows pride of workmanship and is suitable even if you're not into a seriously Southwest style. It's both contemporary and classic. Did I mention gorgeous?

Turquoise stones should be protected from chemicals and never placed in a heated, ultrasonic jewelry cleaner. To clean my silver pieces, I just use a small amount of plain, white toothpaste on a dry cloth (avoiding the stones as much as possible), and then rinse under plain water when the tarnish is removed.
