The mineral zircon, known as zirconium silicate, is commonly found as a minor constituent in igneous rock such as granites and some kinds of metamorphic rock. Gem quality zircon stones are usually rare. These gemstones are formed mainly in pegmatites (coarse-grained igneous rock) and in fissures.
Temperature: A copse is flaccid immediately after death, muscle stiffening, rigor mortis, commences after about three to four hours, reaches maximum stiffness after 12 hours, and gradually dissipates until approximately 48 to 60 hours (two and a half days) after death.
Rigor mortis sets in around two to six hours after death. Decomposition: For a few days after death, some cells (such as skin cells) are still alive. Because of this, the live bacteria starts to break down and putrefy the body. Colour: First the body turns green, then purple, and then eventually black.
