This limited edition heart necklace has sold out every month... each month 10 different heart necklaces are released. This month with the diamond being the birthstone for April, I found this necklace to be perfect for the month. These delicate pieces of sea glass have been found along the shores of Long Island and carefully drilled and stacked to create this beautiful clear sea glass trio necklace.
