November is lucky enough to have two birthstones - this post is the second for the month.
Citrine
Citrine, one of November's two birthstones, known for it's saturated yellow to reddish orange color and durability, is a member of the quartz family. Citrine is rare to find in nature, and most citrine in today's market is a result of heat treating amethyst (purple quartz) to bring out the yellow citrine is prized for.
Shopping for Citrine
When shopping for citrine, assume all of it has been heat treated, unless otherwise proven with a GIA report. Citrine is a great option for anyone who is looking for a yellow gemstone as it is a very affordable option from small carat weights to large carat weights. When shopping for Citrine, ideal specimens are free of inclusions and have vivid color tones.
Citrine is also frequently purchased in geode form, exposing the rough crystal formation. In geode form you can also find ametrine, a combination of amethyst and citrine in the same crystal. This is a sign that part of the crystal structure was heated (Citrine) while the other part (amethyst) remained in it's unheated form.
Caring for Citrine
As citrine is a member of the quartz family, it is very durable, making it ideal for setting in rings and bracelets which are more prone to heavy wear. It can be cleaned using a toothbrush and warm, soapy water. It should be stored away from other softer gemstones as it can scratch and damage their surfaces.
