Specifications

Quartz (Prasiolit Variety)F:SiO2,25kg,6Mohr's Scale of Hardness,2.6g/mg,Red Jasper,F:SiO2, 23kg,6.5-7Scale of Hardness,

Green Quartz, A silica Glass that consist of nearly pure silica (98% of SiO2).  The material is brittle and has the tendency to shatter within creating in-situ fractures which consequently induces multiple internal defractions.  Apperars to have a faded green colour from the conchoidal flakey peripheral edges and consequently grades into a more darker green towards the core of the glassy matrix.  Owing to its close resemblance to quartz, this glassy rock bearing the characteristics colour (green) of a quartz variety called PRASIOLITE.  With or without the external tint, glasses faceted from these material lack brilliancy and have a very limited amount of dispersion owing to their low DR value between the B-G interva.

 

Red jasper:Opaque and fine gained, this particular sample of jasper occures predominanly in red.  Categorizes into the calcedony family microcrystalline quartz, this jasper is partially organic due to its deposition/redposition history. Obviously iron rich minerals within sediments during the formation eventually got concenterated after slow and gradual sediments burial and lithification which consequently allows for compaction and water weaning that gives rise to the colour. This process is later followed by silification to become quartz. Fractures are evidently conchoidal with flakey edges.
