chrysoprase. Um can we say gorgelicious? This unique gem created by Zoe and Morgan, set in a gold surrounded by white sapphires is a stunner. Or even this one, created by the same designer. I'm pretty sure either one would fulfill the desire for something unique. For more chrysoprase jewels go here, here, here and here and hey what not coral as an alternative?
