Delightful
Birthstone first. It's a typical crystal chip in a natural form. Nice chain. Nice mount.<br /><br />Many years ago, I seam mined for this tourmaline-related class gems in the Pala mining district of San Diego Cty, CA. My proper gem ID equipment is too deeply packed away to conclusively ID as aquamarine. But, from experience and hardness check, it's in the aquamarine class hardness.  There are named variations based on crystal structures, some rarer than aquamarine, that formed in the same ancient hot spring vent matrix where this formed that might be confusable with the aquamarine. Yes, there are aquamarine-colored emeralds, but this isn't that. The matrix cooled too quickly (geologically) to grow into a larger clear form.<br /><br />As advertised.
