Australian natural boulder opal pendant with leather necklace

Natural boulder opal pendant with leather necklace purchased in Cairns, Queensland, Australia. See pics for measurement. The leather cord is extendable (32 inch) and can be shortened to be a choker. I usually go on a buying frenzy on trips and then return home to Canada without ever wearing or using them. This is one of those. Bought this because I wanted a piece of natural Australia, and I liked the leather necklace that goes with the natural look. Color may differ depending on different lighting and different monitor settings. I am a Canadian seller based in Ontario, and I ship to the US by paying a cross border shipper to courier the parcel across the border to the U.S. and transfer to USPS which you pay.
