Misconceptions
Rough gemstones and loose gemstones are not the same. Rough stones are in their raw or natural state and loose gems have been tumbled or cut and polished. Rough gemstones may cost less than their loose counterparts, and they have the advantage of being in a pure state for future use. Some popular rough gemstones include emeralds, sapphires, opals, aquamarine, peridot, and rubies.
Function
Rough gemstones can be tumbled in preparation for jewelry settings or other decorative purpose. Ornamental uses for rough gemstones include filler stone around displays, such as fountains or plantings.
Considerations
Rough gemstones are available online or in shops that sell gems in or around major metropolitan areas. Many shops will process telephone orders and ship the gemstones. Rough gemstones are available in bulk and by the pound. Some sources will sell gemstones in "grab bags" containing multiple varieties of type, size, and color.
