Citrine Clusters are reputed to bring good luck and fortune into a house.
 
A beautiful yellow colour, citrine is formed when there is a huge heat source next to an amethyst deposit. Likewise, heat treated citrine is treated amethyst. 
Natural citrine is rather rare these days, so 90% of the stuff on the market is treated amethyst. 
I am unsure as to whether these are natural or not, so I will advertise them as heat treated.
