The second birthstone for March is bloodstone, a dark-green stone flecked with vivid red spots of iron oxide. Generally found embedded in rocks or in riverbeds as pebbles, primary sources for this stone are India, Brazil, and Australia.
Bloodstone is also called heliotrope, a word from the ancient Greek that means “to turn the sun.” Many believe it was probably named such because of ancient ideas about how minerals reflect light. In fact, some believed that the sun itself would turn red if this stone was put into water.
Bloodstone is sometimes also known as another name, Blood Jasper. But really these stones are chalcedony, a crypto crystalline quartz. There are two forms of bloodstone: one is more transparent (heliotrope) with red spots while the other is more opaque (plasma) and has little or no red spots.
For those looking for a good quality bloodstone, it is generally considered that a solid green color with visible veins of red is best. It also comes in many shapes and cuts including traditional cuts like emerald, oval, and cushion.
Bloodstone may not have the overt beauty of aquamarine, but many prize this stone for its symbolism and other properties.
