I was going to wait to post my spinel separately when it arrived should be here on Monday. I bought this beautiful spinel from Michael E at gemshoppe.com after months of pestering him for a spinel. Anyways It looks amazing from the pictures, it started out a light lavender rough, then apparantly after cutting it, it became a color changer, which I''m so excited for, It appears to change from two distinct color as Michael described it. Incandescent lighting it turns this purplish color, outside, it turns medium blue. so I''m not sure what kind of setting to put this in? I like this halo but is this too much going on? i''m so used to solitaire but I want to oomph my collection a bit. what do you think? I thought of doing a simple soltaire with the hand over hand whiteflash double prongs or this, or something else? it is 6.5mm
