Click the Submit button to display a list of minerals with the chosen properties.

To identify a gemstone at Minerals.net, hover the mouse over the Gemstones tab on the main page, select a color, and then compare your sample to photos of gemstones displayed on the page.

To identify a mineral at HiddeniteGems.com, click the Gem and Mineral Identification tab on the left side of the main page, and then click the link associated with the color of your sample to display photos and other details of gems and minerals of that color.
