Haleakala?

I've seen it and even took an early morning bike ride downhill from Haleakala on one of my vacations to Maui. This latest resin ring so reminds me of a volcano glowing with shades of bright fire surrounded by red-hot embers! What gives it this magnificent glow?  I embedded a 27mm Swarovski Padparadscha crystal in the resin cabochon, which causes the depth of glow to change depending on lighting conditions. My "Faux Volcano Crystal" ring is huge! Measuring 35mm in diameter, it is more than a statement piece...it seems to have a life of its own! I love it!
