Diamond Simulant ... Non-destructive testing is preferred because most suspected diamonds are already cut into gemstones and set in jewelry, and if a destructive test (which mostly relies on the relative fragility and softness of non-diamonds) fails it may damage the simulant—this is not an acceptable outcome for most jewelry owners, as even if a stone is not a diamond it may still be of value...

Native American Jewelry ... Native American jewelry can be made from naturally occurring materials such as various metals, hardwoods, vegetal fibers, or precious and semi-precious gemstones; animal materials such as teeth, bones and hide; or man-made materials like beadwork and quillwork...

Jewellery may be made from a wide range of materials, but gemstones, precious metals, beads and shells have been widely used...

Diamond Enhancement ... The CIBJO and government agencies such as the United States Federal Trade Commission explicitly require the disclosure of most diamond treatments at the time of sale.
