This spread originally came out in the the June-July 2010 issue of View Magazine and I've actually just seen it now. What a great photo of Heart!
This is the ring she wore. Antique square cushion cut yellow sapphire in yellow gold with rhodolite and pink sapphire pave in textured silver on a carved buffalo horn base. Exotic, yes, and space age as well as this was from the Futurism collection a couple years back. One of my favorite pieces.
Many thanks to Samito Jalbuena
