Wow, what a gem, I love concave cuts!LisaRN|1462632476|4028580 said:It's interesting how gemstones can shift colors in different lights. Spinels are famous for this. I took a pic of this pink spinel at my computer desk the other day. You can see how the color shifts where the LED ceiling light hits the stone. I thought it was a fun pic so thought I would share.
