Lapis and the Jade one are THE colors for Spring this year...That said, I think you should get the one that matches your skintone and eye color well. It will be the most flattering.
Went to Tiffany this past weekend, they dont have it in store. Available online only. But my SA said that the pendant is super tiny, less than an inch away...cos they meant to be worn as a stack.
I dont know if I want it now...
