We can buy in bulk for you from miners as goods come in, just let us know what you need, we can discuss prices, availability, quality, but it will require you to pay for goods in advance before we start purchasing for you. Be aware that goods may not be readily available from miners once you place your orders, and some, and in many cases, many mines may be closed, your order may just make the miners (artisan miners and small farmers who have stones on their land) re-open their mines and start mining. It can take a few months to collect goods and it can also come in full force when a mine opens, for a limited time. We will not be able to change or cancel the order once placed (when buying for you) as we place orders with the miners and they make onward commitments. As usual, all are ethically sourced, traceable gemstones, and if you like, and are buying continuously from that particular mine, we can provide photos and videos of the mine/mines you are buying from and the communities that benefit from around the mining area. We have our buying office in Arusha in Tanzania, our own office, and we sell out from the UK, it’s easier to ship parcels from here and accept payments too, it also gives a sense of security to the customer as the transaction is fully guaranteed and secure. We sell all our stones at the same price as we would if you were buying from us in Tanzania, and pride ourselves on the best quality and selection (decades of networking and experience), and acquiring the best grades as we can from the miners for you. Our main focus is for fine grades(We can provide any grade you like based on what your requirements are). We ship worldwide. Feel free to buy small singles and small lots off the website (they do run out fast though) and if you need any large lots (any grade) just feel free to contact us (you can contact us at any time, not just for large lots).
