WIEDE´S
was
established in 1903 by Dr. Ing. h.c. Alfred Wiede at the village of Aigenstadl near the town of Freyung / Germany to produce Calcium Carbide, which had been a basic pre-product for the chemical industry at that time. |
||||
|
Alfred Wiede´s interest in gemstones went
back to impulses during his
studies
at the world´s oldest mining academy
of
Freiberg
/ Saxony.
So
he started up a ruby production in 1913
as
an addition to the carbide business.

|
In the 2nd half of last century new petrochemical processes marginalized the Calcium Carbide business, leading to focus R&D on special Synthetic Corundum Crystals for various applications to be supplied worldwide for decades now. |
||||
| In the
late seventies of last century Cubic
Zirconia - as an almost perfect diamond substitute - was added to the range of synthetic rough crystals. WIEDE´S tradition as family enterprise for more than one century is carried on now by the 5th generation. |
