25.1mm x 26.4mm x 5.5mm (19ct)The #8 Turquoise mine is depleted and no longer mined.  When the turquoise that is still in circulation is gone, it's all gone.   No more to be be mined.   Photo does it no justice.  Great piece for a stunning focal point with metal clay or wire wrapping!   Sizes are approximate, color may vary from photo.   Photo taken under LED light.
