Bony Levy Colorful Bubble Ring Solid 18k Gold size 7

I'm the original owner of this pre-loved piece. It is a discontinued design of a limited edition piece by Bony Levy. The ring is done in solid 18k gold and is a size 7. 

The ring features .43ctw of guaranteed natural gems. I've not tested each but as a gemologist, these stones appear to be, at surface glance, no loupe:

Ruby

Madeira citrine, or mandarine garnet

yellow sapphire

pink sapphire

tsavorite garnet

emerald

blue sapphire

light blue sapphire

pink tourmaline

and light ruby/hot pink sapphire.

The weight of the ring is 2.5g and the "bubbles" are about 3mm wide with their bezel. This ring makes a nice stacker
