Citrine is the birth stone for November. Imperial Topaz is the original stone, for November, but due to it's rarity it was changed to Citrine. Almost all Citrine is created from heat treating pale Amethyst. There are natural Citrines, but they are rare. I have two other Citrine pieces in my Etsy store, the ring shown below is Citrine and White Zircon, and is available in my Ebay store.
