This is my newest design inspired by lava embedded with the shape of coral from thousands of years ago.  I was on a hike in Maui and came upon this sight and it was so unusual and beautiful.
This is the large size shown in photo and measures 2 3/4" high and 1 3/4" at it's widest.  I put this on a dark brown leather cord. You may select sterling or 18k gold plated when adding to the cart. See photos on this page for size comparisons and sterling silver option!
