Prussian Blue Agate
Not to be confused with NMGs recent Blue
Quartz/Agate material, NMG China facility is pleased to announce
successful chemical treatment of their agate. Using translated secret
German recipes dating back more than 120 years, from the famous
gemstone region of Idar-Oberstien, Norcross Stone Treaters have
successfully changed grey banded agate into beautiful Prussian Blue
Agate.
Idar-Oberstien is also the birth place of agate chemical
treatment. NMGs Gem Surfaces brand is now producing blue agate slabs
(granite slab standard sizes), tiles and furniture. Madagascar Minerals
will be offering all their customary polished products in blue
agate. NMGs Thierry Andrianarismasy started treatment of cut agate
slices, however, due the slab polishing process, the penetration
wasn'tt deep enough. After a few months of experimentation, Gem
Surfaces succeeded at treating a full size, 400kg granite slab (agate
gemstone) in one streamlined process. NMG claims this safeguarded
technique to be the largest ever successfully achieved, on record.
