The natural catalog

The real thing: natural gems at the top of the market

278 mined gems sold on Amazon, most with a report from GIA, GRS or IGI: GIA-graded diamonds, unheated Burmese rubies and Kashmir sapphires, big D-block tanzanites, spinel, emerald, alexandrite and Paraiba tourmaline. The most expensive is about $53,000. Most of us will only look, and that is the point: this is what rarity costs. Each gem page shows the lab-grown version of the same mineral for a fraction of the price.

How a listing got in, and how to buy one safely
  • Named natural, with a report. The title says natural or mined, and almost every stone names its lab report (GIA, GRS, IGI or AGL). Nothing lab-grown, simulated, or treated fancy black.
  • Check the report yourself. Before you pay, ask the seller for the report number and look it up on the website of the lab that issued it. The weight and measurements must match the stone.
  • Unheated means the colour is as it came out of the ground, which can double the price of a ruby or sapphire.
  • Prices are rounded and change often; the Amazon page is always the real price.
