The symbolism is very clear: dragon eating it's tail and OM. Pendant is bigger and a bit heavier than you might expect. Chain complements it perfectly. I'd say it's actually a unisex item.
Wow. Beautifully made, elegantly designed and I'm delighted with how she used a uniquely designed clasp that's easy to put on and off. No more fumbling with teeny clasps. What a gifted artist. Thank you Sugi and thank you Novica!
