These rings are handmade in 95% pure silver, by using 1 mm thick silver wire in round profile. The surface is brushed (2 rings) and hammered (1 ring). We usually make rings in US sizes 4-9; if you would like to order a bigger size please contact us before ordering so we can create a private listing for you (price might vary). We also made these in rose gold version (listed separately). They are lovely on their own, stacked with other silver rings, or in combination with rose gold rings. All our products are handmade in a Karen hill tribe village in Northern Thailand where we work side by side with the local silversmiths. We ship from our main office in Bangkok. Products come in original packaging and include tracking number for safer shipping.
