"GONDAR" FIELD OPAL ETHIOPIA
This natural untreated specimen is from a stunning new find in the Gondar area of Ethiopia.This specimen is called hydrophane as it changes colour from white base to crystal when emersed in water .From our experience most of the material from Gondor is hydroplane.We have taken the photos dry and wet to show the difference.The wet specimen is placed on a black backing which gives a real kick to the colour
Always let the stone dry out slowerly-do not place under strong hot lights.
We have rubbed parts down genlty on a 600 rubber wheel so there are no visible scratch marks.
The opal is not as hard as Australian material as you can feel that it is softer when rubbing it down..There is not much history to this opal but it feels healthy.The chocolate variety has been around for app 15 years and is well known.It appears to be formed by a sedimentary process unlike the other Ethiopian opal which is from Rhylotic Nodulars and can have a lot of matrix around it.This opal can be cut in to a stone or it be be kept it in a specimen jar with water and admire its stunning brightness which is brilliant 5/5.
