our Bohemian Garnets / nase ceske granaty

Garnets are one of the largest families of gemstones. There are about a dozen varieties of garnets found world wide; they come in all colors except blue. The name 'Garnet' stems from the Greek word for pomegranate, a fruit with clusters of fiery red seeds. The Czech Republic in Europe is one of the few places in the world where the 'Pyrope' variety of garnets can be found. The pyrope has the deepest fiery red color of the entire garnet family. This unique garnet is world reknown as the famous Bohemian Garnet and has been mined from the mountains of Bohemia for over 600 years.

Garnets were highly popular in Europe during the 18th and 19th century and enjoyed great admiration and demand during the Victorian age. The traditional hand-crafted Bohemian design places great emphasis on the arrangement of the garnets which dominate over the metal in each individual piece of jewelry. The brilliant sparkle of the Bohemian Garnets is due to their excellent clarity, transparency and high refraction of light.
