 GEMSTONE MARBLES

 PICTURE JASPER


This is Picture Jasper (yellowish and picturesque) gemstone marbles. These gemstone marbles are exclusively designed for customers who has previously bought the Chinese Checkers chess set with classic glass marbles. The production of these gemstone marbles is from a different source other than the chess producer. This will ensure the gemstones are produced by competent persons in their trade.

While the same type of gemstone is classified into different gradings, I have specifically requested the gemstone producer to supply me with what they called the "A" grade product. These are the ones with the best quality and also the highest unit cost. There is also a further selection process when I collect these gemstone marbles: the gemstone producer manufactures more than my ordered quantity, so that I may pick the best among the best. These processes have minimized the possibility of defects in the gemstones, and also reduced variations between the same type of gemstone marbles.

 

THE TYPE OF SELECTED GEMSTONE

Picture Jasper:
Jasper is a very pretty, inexpensive earthstone. It means "spotted or speckled stone" in its name. Based on archaeological recoveries at the Palace of Knossos, the history of jasper dated back to 1800BC when jasper was carved to produced seals (see references).

Jasper is an opaque rock. The picture jasper that goes with this chess set exhibits combinations of patterns, which are formed in the process of hydrothermal circulation, when the original silica rich sediment and volcanic ash consolidates and deposits.

Jasper was also known as a protection gemstone, with the power to drive away evil spirits.
