Plucking some rough from the ever growing piles is no doubt fun at times but also an increasing weight to bear, creating a space just shouts louder for more finds & purchases to fill, this green and yellow agate called loudest, perhaps gaining in popularity,
it seems to have adopted the name of the mythical singer orpheus from the (same region) Rhodope Mountains Bulgaria which was first given to the mineral Hinsdalite, nevertheless this agate is found with celadonite(silicates of manganese, iron, potassium)
and brown, yellow jaspers, with it occasional clear or dendritic areas it can produce wonderful landscapes.

HOW TO CUT TOURMALINE

Tourmaline is to me a truly fascinating gemstone. I am attracted by the wide range of colours in which it occurs and by its property of dichroism which can lead to even greater variety within the same stone. Don't worry about the term dichroism if this is new to you. Any gem crystal that is dichroic has a structure which absorbs light differently depending on which way it passes through. This property is only
significant optically from a cutters point of view. A piece of tourmaline without obvious physical problems will cut and polish well in any direction, but looking at how the light is behaving gives us some choices as to how the finished stone will appear.
