In this category will find pairs of unique Australian Koroit Boulder Opals and Yowah nuts in their natural raw extracted state, unshaped to any specific form. Some are pieces, sometimes splits, of the original host material, or in case of nuts, they are can be the entire boulder found. Use these stones as they are or perform your cut and polish.
Rough Opal is the natural form of Opal. It then takes many hours of delicate and precise handling by a skilled lapidarist to shape this material into the wonderous gems that can be seen. Because of this, rough Opal is an excellent bargain for those who wish to try their hand at carving something precious.
“Pairs are a lot rarer than single stones resulting in higher price values.”
Koroit Opals, are part of the Boulder Opal family which are characterised by solid brown ironstone matrix or layers interlaced with the opal and are the second most valuable opals in the world after Black Opals. Koroit Opals take their name from the Koroit mining area near Yowah in South West Queensland and due to their unique pattern are more sought after than light opals.
Yowah nuts are mini boulders of 5mm to 20cm which host an opal, also specific to the Yowah region.
These Rough pairs from Koroit and Yowah are perfect for any enthusiast who wishes to test their skills at cutting harder material.
