The feature of this necklace is a fabulous, natural Welo Ethiopian Opal pendant with the most outstanding play of colors. 

The pendant is a pear shape measuring at a size of 18mm x 13mm x 8.5mm with outstanding luster and flashes a rainbow of colors (see video), with a carat weight of 9. I've adorned this fabulous pendant with a lacey accent of solid 18k yellow gold along with a petite bezel set natural ruby, all of which dangles beneath a curved bar and links of also solid 18k gold.

Length of necklace is 18.5", the perfect October birthstone necklace in high karat precious metals for a lifetime of enjoyment.
