Gemstones

Our Gemstones category includes natural diamonds, rubies, sapphires, emeralds, amethysts, topaz, turquoise, opals, citrines and more. Also, stones, minerals and others kinds of rock species, including what were formerly known as semi-precious stones. In other words, most anything and everything that falls under the category of gemology.
Although the lion's share of listings in this category are for rough stones, polished diamonds are foremost among our most highly-valued lots. A significant number of these stones already to have gone under the hammer as well as those currently up for auction come with grading reports.
Our Gemstones category also covers amber, quartz and various organic, stonelike materials. This is the place to look for that special stone if you plan on designing your own rings, brooches or pendants.
