to answer a few questions; pricing i will finalize in around 2 weeks, i will let people know publicly with that, so no need to PM me we will be stocking originally in EU but later in US also, regarding the 'fmaily' or type of crystal, we can say this, its hard to say which family it is from, and makes little difference now days, if rather you are asking purity rather than family it would be comparable to silver product in the percentage of high 80's and low 90's, but as i say, the family names people throw about mean very little these days. greets GE
