Mineral Specimen #5199 Turquoise
5.7 x 4.4 x 5 cm
A large Turquoise nodule with an outer rind which is much darker than the inner core. The first question about this specimen is "Is it dyed?". And the answer is No. Although the interior is much lighter, this appears to be natural. The color is too uneven in the surrounding, darker rind. Also, there was part of a price, in magic marker, on one surface. Most of this was removed with Acetone and there was no blue color on the paper towel when this was done which would have been the case with dye. Also, the iron stained material on some of the surfaces would also have likely been stained. This surface has been partially polished. Although there was no location listed for this piece, it is likely from the American Southwest.
Flaws: There is still a little magic marker on one surface.
