Shiny Recycled Gemstone Easter Egg! 25/03/2024

Another genius idea from Gemmology Rocks! Instead of chocolate for Easter, gift someone (or yourself) a gemstone in an egg. It's the better option for your waistline :)

Shiny Recycled Gemstone Easter Egg! Waaaay better than chocolate! US, Canada & Mainland Europe customers: you can still order, but it is unlikely to get there by Easter. Delivery times are 3-7 BUSINESS DAYS. A recycled gemstone in a shiny golden egg, what more do you want? Each egg will be packed with one of our recycled gemstones...

A tale of two diamond certification schemes: the Kimberley Process and the G7’s Russian diamond ban The diamond trade is today faced with arguably the biggest crisis since the blood diamond controversy of the late 1990s.

Initiatives in Art and Culture celebrates Moyo Gems. Building on a gemology education initiative developed by the Gemological Institute of America (GIA) in collaboration with NGO Pact, Moyo Gems provides the world’s first sustainable market for colored gemstones from artisanal sources. Meaning 'heart' in Kiswahili (the dominant language in Tanzania and Kenya) and in some other languages on the African continent, Moyo Gemstones is an ethical gemstone collaboration with Tanzanian Women Miners Association (TAWOMA) to assure that artisanal women miners and their allies receive fair market value for the gems. Moyo Gems is operated by the nonprofit development organization Pact, which collaborates with the Tanzanian Women Miners Association, the Association of Women in Extractive Industries in Kenya, East African exporters, and the responsible international trading companies ANZA Gems, Nineteen48, and Maison Piat. The initiative's goal is to empower women miners to work safely, mine better, improve financial security, and create stable, equitable markets for fair trade.

We encourage you to join IAC in supporting this initiative through purchasing the gemstones to use in your jewelry or by donating via the Network for Good page: https://donatenow.networkforgood.org/moyogemstones

All donations are tax deductible.
