BLOODSTONE

BLOODSTONE
Bloodstone is dark-green variety of the silica mineral chalcedony that has nodules of bright-red jasper distributed throughout its mass. Polished sections therefore show red spots on a dark-green background, and from the resemblance of these to drops of blood it derives its name. Its physical properties are those of quartz. It is also known as heliotrope. Location - Australia, Brazil, China, India, USA Group - Quartz R.I. - 1.53-1.54 Hardness - 6.5 - 7
