Ametrine: Beautiful ametrine gemstones. The center stone is a traditional 50/50 split of amethyst and citrine. The stones on the left and right are artistic cuts that allow light entering the stone to pass through purple amethyst and yellow citrine and blend into beautiful shades of orange, magenta, peach, and a range of other colors.

Specific Gravity of Minerals . Specific gravity is the density of a material, in this case a mineral, compared to an equivalent volume of water. If a piece of galena has a specific gravity of, that means that it is times heavier than a volume of water identical to the volume of that particular piece of galena.
