Well ZAM! Thank you Clive!!

Thinking Cap Powers GO!

Hmmm, Quartz, Silicon Dioxide - SiO2. Too many inclusions to be cut into a faceted gemstone but a very nice specimen; uncolored so it grew in an underground "vug" of hot, SiO2 saturated water uncontaminated by other soluble minerals. The inclusion of Iron and possibly traces of Aluminum (Aluminium for you Brits) into the crystal structure as it grew would have colored it Violet (Amethyst) and subsequent heating would have turned it Yellow or Orange (Citrine). Not having a scale by which to judge its size I can not say how long it took to grow but it would have been a very long time in any case.

Nice Photo!!!

:D

I think it's about 4 inches (10 cm) long, so I guess it must have taken several killion years to grow. Thanks for the fascinating info my friend!!!! :icondorkydanceplz:

The growth of a crystal of such size undoubtedly took quite a long time in a natural environment though very large cystals (up to 2 kilos) of exceptional quality and in many colors are routinely grown in laboraories in only a few weeks. These materials are relatively inexpensive (a 1 kilo crystal of colorless Quartz can be had for about 100 Euros) see: [link] if you are interested in Quartz or any other laboratory grown crystals such as Emerald, Ruby, Sapphire, etc.
Single and poly-crystalline materials of high purity have many useful properties and are essential to our modern way of life. Green semiconductor Lasers use a crystal to double the frequency of light emitted from an infrared (invisible to us) semiconductor Laser into visible green light (it's actually a three-step process in which 808nm light from a semiconductor Laser pumps a crystal of neodymium-doped yttrium aluminum vanadate which lases at 1064nm, this light is then frequency-doubled by a crystal of Potassium Titanyl Phosphate to produce the output at 532nm) This complexity accounts for the greater expense of green laser pointers, but I digress...

What was I on about?
