    Introduction

    Bloodstone is green with red dots and some say the dots resemble droplets of blood. This unique blend of colors gives bloodstone its descriptive name. Bloodstone is also known has heliotrope. Heliotrope comes from the Greek words turning and sun, with the belief that if the stone was immeresed in water the sun would turn red (www.controversial.com/Bloodstone.htm).

    I was interested in this common but odd looking stone and created this website on the topic for my gemstone course at Emporia State University. The page covers bloodstone's: (a) basic properties (b) use (c) geographic location (d) common imitations (e) associated myths and facts.

    Bloodstone as Jewerly

    Bloodstone is somewhat rare but a relatively inexpensive gem. When fashioned, it is usually cut en cabochon for pendents, rounded into beads for necklaces, and carved or cabbed for men's rings. Bloodstone can also be used as a sealstone (24carat.co.uk). Bloodstone used in jewelry requires the usual suggestions for protecting this beautiful gemstone from scratching, harsh chemicals, extreme temperatures and sharp blows. It is also important not to get the stone wet, for the polish could be removed if the stone gets wet (24carat.co.uk).


    Mystical and Healing Powers

    For many centuries people have thought of bloodstone as a magical stone likely because of its odd coloration. Some believe it helps one become knowledgeable of the ways of the world. Others believe bloodstone stops hemorrhages and reduces stomach and bowel pains. Also bloodstone is thought to assist and strengthen organs that purify the blood (All~That~Gifts.com). In addition to all of these powers, some think bloodstone assists athletes who wish to gain added strength (Controverscial.com).


    The Marytyr's Stone

    Bloodstone has also been known as the Martyer's stone. It was thought to have formed from the blood of Christ as it fell on to the Earth and solidified (allthatgifts.com). From that time on Medival Christians carved martyr and crucifixion scenes on to the stone giving it, its name "The Martyr's Stone" (GembyGem.com). In the Middle ages Bloodstone was thought to have miraculous powers, one such power believed to have been the power of invisibility.


    Origin of Bloodstone

    Bloodstone is a chalcedony or cryptochrystalline varity of quartz. It is primarily mined in India, although occurrences and mines can be found in Brazil, China, Australia, and the United States, specifically in Wyoming (Wikipedia.org).
