Technical ways to determine if a piece of jewelry is genuine natural turquoise is to remove it from the bezel and put a jeweler’s grinding tool on the bottom of the stone and see if you can detect the smell of burning plastic. Another test is to tap it with your fingernail and see if it sounds like plastic or stone. Still another test is to look at the stone under a magnifying glass or loop and see if you can see what looks like a honey-colored tinge piling up in the cracks or matrix of the stone that is the plastic.
These methods are beyond the capability of most people evaluating jewelry who do not have physical possession of the piece – as when you are buying jewelry for sale online.
When buying online, the most important factor is to purchase from a reputable dealer of antique Native American jewelry. The seasoned professional can look at the total picture – the stone, the matrix, the texture, the style of jewelry, the wear - and comparing that with thousands of pieces they’ve held in their hands before in order to make an assessment.
