Unique Vintage CZ Ring on 925 Size 6.25

Estate sale find; unusually shaped with a bit of a modern/contemporary slant. I tested the stone and although it looks like a sparkly diamond, it is not. Ring is marked 925 inside shaft and may possibly have other marks that are extremely faint. Although it’s marked 925 it has a gold/bronze hue to it. The shaft is quite thin. No flaws that I note; ready to wear! This sizes as a 6.25. Box is included.
