Dioptase

Dioptase is chemically hydrous copper silicate which forms as small crystals
of deep, emerald green with a vitreous lustre which in good specimens is
strikingly beautiful.

Dioptase is unsurpassed in its ability to heal a broken heart with the Power of
Love.

Although it resembles and is often confused with emerald it is a much softer
Stone and not well suited for jewelry.
