Chrysocolla has an attractive blue-green colour and is a minor ore of copper, having a hardness of 2.5 to 3.5. It is also used as an ornamental stone. It is typically found as glassy botryoidal or rounded masses and crusts, or vein fillings. Because of its light color, it is sometimes confused with turquoise. Commonly it occurs only as pourous crusts unsuitable for gem use, but high quality, gem grade chrysocolla can be translucent and is highly prized.
I got these specimens from Kinokuniya, look at a close up picture, can you notice the circular habitat?

My Jewelery Box, a shopping portal that only sales jewellery but also educates its consumers, is having a sale whereby its jewellery is going at nearly liquidation prices! There is a wide selection of goodies available! I just saw some diamond studs going at good prices, not to mention other pieces with emeralds, blue topaz, green amethysts, opals, citrines. One of the things that caught my fancy was an elegant, yet simple, silver dog tag! I saw a similar design at a show some time back, and trust me, the price tag then is more then 5 times the current price it is on sale now!
In this add-on, there is a white sapphire, a blue sapphire, a green sapphire and an untreated Vietnamese ruby!
