This is very green quartz, and it’s natural. (unlike the unfortunate material being marketed as “amegreen” – Uruguayan amethyst that has been tortured in a facility by exposing it to radiation until it changes colour – but I digress…). This is a specimen of sparkling druzy quartz with inclusions of micro dioptase. There are a few rounded colourless calcite crystals in association. In excellent condition, no damage. A colourful and unique quartz from a lesser-known find from a few years ago.
