I've been reading up a bit on gemstones. Citrine is very pretty but it's actually an adulterated amethyst right? Is it considered a very low-end type of gemstone?
I found this on this website regarding Citrine. http://meanings.crystalsandjewelry.com/citrine/
Citrine is a yellow variety of quartz. Stones that gather their color from inclusions or surface coatings are technically not citrine. In practice, because natural citrine is rare, much citrine on the market is treated amethyst or smoky quartz which is heated to make a type of treated citrine.
