This is a one-of-a-kind Ethiopian opal, sourced from a jeweler in Yamanashi and crafted. It's a very beautiful opal, with lots of play-of-color in pink and green. The opal measures approximately 14 x 10mm. The pendant top frame is silver with 18k gold plating. There is a hallmark on the bail. The chain is included as a service because the bail is small. It's made of hypoallergenic stainless steel and is approximately 50cm long. This is a great value. Due to the high cost of the high-quality Ethiopian opal, further price reductions are not possible. If you are interested, please make a purchase.
