Lovely large heart old green turquoise “ your turquoise turning green is a good sign, as real turquoise gemstones turn green over time. Turquoise gemstones are porous and absorb oil and water, which causes discoloration over time.” Approximately 1+” in width and 1/4+” thick. Has a hole all the way through to thread a silver chain through (or maybe a leather cord). The great thing about turquoise is that it goes with anything and has always been in style. B
