Absolutely no offence taken Sue,
unless you are 'into' Crystal Therapy you couldn't be expected to know why we who are, dismiss goldstone as having 'healing' properties.
Goldstone is produced in much the same way as Sach has so clearly described... the 'Lump' of glass and copper mix is placed in the furnace and the outer parts that become overheated are written of as waste, it is the inner core that is not overheated which is used to make the 'gemstones' that are sold as goldstone.
It is very pretty and quite costly due to the wasteage, but it has none of the Piezo-Electric properties of Quartz, and as the colour is artificially produced, neither will it work in Chakra Balancing.
I feel much as m does, that this paperweight has lumps of something unattractive within, and one thought was... could it be that we are all correct, and that these lumps are pieces of the overheated waste goldstone...?? Just a though?
