Opal Size Chart
Dark Crystal Opal Parcel from Mintabie, Australia.
These are three delightful oval shaped dark crystal opals. The photograph brilliantly showcases the complementary colors of the stones, with a predominant theme of blue. The clearer stone has minor inclusions with shimmers of blue and some purple on the surface and is 10.5 x 7.5mm. The other two have an average size of 10 x 8.5 mm and are almost identical in shape. One is dark blue with traces of purple and electric blue and the other is lighter with more traces of dazzling green.
