Citrine facts
Citrine occurs naturally near amethyst and a related quartz mineral. The color of citrine comes from small amounts (about 40 parts per million) of iron in the crystal structure of quartz.

The color of
Citrin varies from pastel lemon yellow to golden yellow to mandarin orange and Madeira red (according to the color of wine). Traditionally Madeira's shades were more sought after, but nowadays Citrin's lighter lemon tones are preferred. Most citrine is mined today in Uruguay, Brazil and many African countries, including Madagascar. Citrine can easily be confused with topaz and has also been called "topaz quartz."
Two colored citrine beautifully blends the bright golden yellow of
citrine with the ice white of white quartz in one stone. Two colored citrine is due to environmental changes during formation. At different times, color-inducing elements (iron) were incorporated into the crystal, leading to different color layers.
