Citrine rondelle faceted 5x3mm. Citrine belongs to the quartz family. Color ranges from lemon yellow to egg-yolk yellow, to orangy or brown amber color. Most citrine is heat-treated amethyst or smoky quartz. Natural color citrine is rare, so it is common to see pale yellow in its color shade. Citrine works well with purple or wine-red colors like amethyst and garnet.
