About Bloodstone - History and Introduction

Bloodstone is an opaque to translucent variety of chalcedony quartz. More specifically, it is classified as a variety of microcrystalline quartz. Bloodstone is characterized by its dark green color and the presence of red, blood-like inclusions, which is how it earned its descriptive gemstone name. Bloodstone is also known as 'heliotrope' and 'blood jasper'. Bloodstone was once the original birthstone for March, but it was later replaced by aquamarine. Today, bloodstone is still an alternative birthstone for March and it is the zodiacal stone for Aries.

Bloodstone's green body color is a result of dense inclusions composed of chlorite or hornblende needles. Bloodstone's color ranges from various shades of light to dark green and typically, the primary color is unevenly distributed, often exhibiting noticeable light and dark color zones. Bloodstone's blood-like inclusions are owed to the presence of iron oxide impurities. The 'blood-drops' can range from red to brownish in color. Some stones may display yellow spotting, these are known in the trade as 'plasma' and are often mistaken for a variety of jasper. Bloodstone's level of 'blood' inclusions vary tremendously. Some may exhibit little to no spotting, while others are very densely spotted. Droplet-shaped blood spots are more desirable than streaks.

Identifying Bloodstone

Back to Top

Bloodstone is easily identified by its characteristic 'classic' appearance. The base color of bloodstone ranges from green to bluish green, and sometimes even bluish gray. The most distinguishing aspect is the presence of red, brownish or yellow 'blood-like' spotted inclusions.

Bloodstone is a variety of quartz and has excellent hardness. There are not many other materials capable of scratching bloodstone, therefore, a simple scratch test can often distinguish bloodstone from imitations. Bloodstone is composed of silicon dioxide and it has a trigonal crystal structure made up of microcrystalline aggregates. It can sometimes be confused with jasper, but because jasper has a much more grainy composition, they can be easily distinguished from one another.

Bloodstone Origin and Gemstone Sources

Bloodstone Gemstone Mythology, Metaphysical and Healing Powers

Back to Top

Bloodstone dates back through historical and ancient times. The trade name of 'heliotrope' originated from the belief that gemstones were once thought to reflect the sun, derived from Greek words that refer to 'the turning sun'. Heliotrope is also mentioned in Boccaccio's stories in the Book of Prince Galehaut, known as the 'Decameron'.

Bloodstone in Religion

The Christians have a very long history of bloodstone use. It is actually one of the most significant gemstones in Christian scriptures. Bloodstone was believed to have been created by the blood of Jesus Christ. It is said that during his crucifixion, the blood of Jesus dripped down from his wounds, staining the green colored jasper placed below his feet. His red blood forever stained the green stones, giving birth to the bloodstone we know today. The name, 'blood jasper', was derived from the Christian legend, but technically, the name is very misleading since bloodstone is not actually a type of jasper stone.

Bloodstone was also known as the 'stone of martyrs'. Throughout historical times, bloodstone was commonly used for the carving and sculpting of symbols and seals that represented martyrdom and flagellation. The most famous bloodstone is a gemstone carving currently displayed in the Louvre Museum of Paris. It is the seal of German Emperor, Rudolf II, and it is the most famous 'martyr stone' in the world.

Bloodstone was once used in medicines and aphrodisiacs throughout India. It was held in very high regard for its metaphysical and crystal powers. To this day, bloodstone remains one of the most popular gemstones used by alternative healers. Physically, bloodstone is thought to alleviate pain associated from hemorrhages, as well as stomach, intestinal and bowel problems. Most famously, bloodstone is thought to be able to purify blood and improve circulation in its wearer. For centuries, Christians believed that the red spots of bloodstone were the blood of Jesus and therefore possessed the miraculous healing powers of the Son of God.

Bloodstone is the stone for Aries, as well as Pisces and Scorpio. It is also the planetary stone for Mars. Bloodstone is associated with the element of fire and is believed to have a very strong protective energy, linked with the root chakra. It can also be used on the heart chakra as well, but because it holds such strong energy, practitioners advise using the stone with extreme caution. Bloodstone was once the original birthstone for March, but is now an alternative birthstone for aquamarine. Precious gems have long been used for their own specific gemstone meanings and abilities.
