Hi,
I was wondering if people can recommend some suppliers of ethical gemstones, preferably UK based (to reduce postage costs/customs taxes, etc) I appreciate there is no definition or gold standard on ethical stones, but I guess I mean companies that at least have put some thought into it and have an ethical policy and are in some way committed to using mines that don't use slave workforce, etc etc. I'm also interested in reputable suppliers of lab diamonds.
Any general advice in this area also welcomed :-)
Thanks!
