Description

A dealer from Vienna brought this material to the Austrian market about 25 years ago. Many of them get dry and beame dull, only a few were stabile like this particular sample. The color of opal is dark red-brown and it shows intense red color-tones, changing in each angle you look at it. You can see very intense red, but also a little bit of green and yellow. The opal is framed by light matrix. Very eye-catching material in good condition.
