✿ڿڰۣ(̆̃̃•Aussiegirl. Garnet technically refers to a family of gemstones that come in every color of the rainbow except for blue. The gemstone that we usually mean when we say “garnet” is the almandite or pyrope garnet which comes in deep shades of red. The properties that make garnet a wonderful gemstone are its very high luster (ability to reflect light almost like mirror) and range of very strong colors. Red garnets are not especially rare so quality peices can be had quite affordably.
