Sapphires are mechanically separated from the clay and gravel in which they lie by virtue of the former’s greater true density. Their processing, grading, heat treatment and eventual marketing are considered with a focus on the Australian sapphire industry, in particular the industry of the New England Tablelands. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.Sapphires are well known gem stones. The weight of any such item can be found on its detail page. Please also note that the shipping rates for many items we sell are weight-based. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page. When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose.

Note that there are restrictions on some products, and some products cannot be shipped to international destinations. We can ship to virtually any address in the world.
