'''Goshenite''' is a type of beryl stone with no natural hue. Though optically transparent when cut correctly, goshenite can be colored into any primary or intermediate hue with a treatment of high-energy radiation. | '''Goshenite''' is a type of beryl stone with no natural hue.

'''Onyx''' is a type of chalcedony very similar to agate, with parallel striation bands, usually white or black against the color of the stone, which is most commonly found in black, yellow, green and red. If the striations are red, the variety of stone is called '''sardonyx'''. | '''Onyx''' is a type of chalcedony very similar to agate, with parallel striation bands, usually white or black against the color of the stone, which is most commonly found in black, yellow, green and red.

There are a number of opal variants, including the clouded white '''milk opal''', '''pinfire opal''' with its fine iridescence, scarlet '''fire opals''', honey-hued '''resin opal''', opalized fossils called '''wood opal''', gray '''menilite''' and transparent '''hyalite'''. Manufactured opals are called '''opalite'''. | ||

'''Rose Quartz''' is a type of quartz stone with hues ranging from pale pink to rose red, caused by trace amounts of metals in the crystal. Rarely, traces of rutile in a rose quartz can cause an optical asterism to appear in the cut stone. | '''Rose Quartz''' is a type of quartz stone with hues ranging from pale pink to rose red, caused by trace amounts of metals in the crystal.
