Citrines are quartz family and have the hardness of 7. The name of this gem comes from the Latin citrus = lemon, indicating the pale yellow color, which reminds each one of a fresh lemon. The colors of the citrine go from light, pale yellow to pale green to orange to light brown. It is clear and transparent. The beautiful color is replaced by hot temperatures, high pressure and mixtures of manganese, iron hydroxide (causes the citrine from yellow to brown- orange) and titanium. Also this stone specifies properties such as eternal life. Of course you will find genuine silver jewelry and gold jewelry collections with citrines. The branded jewelry designers use colors and stones in your gemstone collections.
