Sembiance Posted June 21, 2010 Share Posted June 21, 2010 I have had this rock since I was a kid. Does anyone know what it is? Link to comment Share on other sites More sharing options...
Fuzzwood Posted June 21, 2010 Share Posted June 21, 2010 Looks like a rock on which a lot of salts deposited on in a crystalline fashion. I see a bit of green so that could be copper or nickle salts. The white could be something like calcium sulphate or phosphate. Link to comment Share on other sites More sharing options...
tomgwyther Posted June 21, 2010 Share Posted June 21, 2010 Looks like part of an an agate geode. Link to comment Share on other sites More sharing options...
JohnB Posted July 27, 2010 Share Posted July 27, 2010 It looks more like a quartz base to me. I've seen Emerald similar to the fourth picture. I have seen this crystal a number of times but I can't remember it's name. I could get shot for this advice but......go down to the largest New Age, Healing Shop you can find. Belief in the healing powers of crystals requires a deep knowledge of the different types of crystals. Let me know if you can't get an answer and I'll take the pics to a couple of my clients for identification. Link to comment Share on other sites More sharing options...
skippy Posted August 8, 2010 Share Posted August 8, 2010 do you know where it came from/what sort of environment it was found in??? That might be able to narrow it down a bit for you.. Link to comment Share on other sites More sharing options...
Subduction Zone Posted August 29, 2010 Share Posted August 29, 2010 Definitely a geode. If you do take it to a New Age shop don't listen to any of their advice as to properties. But they may actually know what it is. Geodes are commonly found in hollows in limestone or volcanic ash beds. The green coloration of the outside, and darker color, makes me lean to the opinion that this one was from a bed of volcanic ash. It would be richer in metals such as copper than limestone would be.

gemni Posted September 10, 2010 Share Posted September 10, 2010 some times rock has a distinctive feature which relates to its original location,I mean specific area where u found it and its surrounding minerals/rocks . The physical properties are also helpful,the simplest test is to drop few drops of vinegar,or hydrochloric acid ,carbonates class is identified by the fumes coming after the acid treatment.
