ETHIOPIAN OPAL POLISH ROUGH 925 STERLING SILVER JEWELLERY
Many Ethiopian opals are sold untreated, while some are treated. Because of their porosity, they are suitable for dye, smoke, and sugar/acid treatments. When all of these modifications are revealed, the opal is substantially less expensive than natural opal with the same appearance. They can deceive inexperienced and even experienced buyers if they are not disclosed.
