Here are two that look good side by side. The one on the left is a yellow citrine I bought from Bill Reid at the Denver Western Regional. No name for it back then. Bill called it: "some kind of yellow, don't worry you will like it." The one on the right is from the 2007 Crown Jewels Magazine Auction, Item no. 109. You can see the similarities and difference. I call it a green citrine Cal.
