Hi Chinwe : We are in a campaign phasing out global gem mining , because it is now obsolete and unnecessary , since chemically identical diamonds, rubies, sapphires , tanzanites , etc. are being produced in small laboratories all over the world . These are conflict-free, cruelty-free, environmentally friendly and support small businesses and are a sustainable path for many communities. Young people love these gems since they are just a beautiful and only a fraction of the cartel prices of DeBeer diamonds !We have the only global standard , the EthicMarkGEMS certification only for gems NOT mined from the Earth. see www.ethicmarkgems.com We would like to hear from you !
