The agate heart reated from "polka dotted agate" was sourced from my very talented lapidary person in Washington state. The piece is phenomenal and the agate can be gazed into for a lifetime! The setting I created is my classic sterling silver prong design with curved heart wire fabrication which has been soldered to ensure a piece to last (with normal wear) the generations. The bail is plain lite shaped with a bar in between to provide ultimate swing time ! Chain shown can be had at extra cost of $100.00 added to price. Otherwise I will provide a plain necklace at no extra cost upon purchase I will provide a choice of neck lace length of 16, 18, 20, 22.
