Pair of QUEENSLAND BOULDER OPAL Reverse Doublets – 14 x 10-millimeter Ovals – Natural & Untread – Made in Australia - New Old Stock - circa 1980s

Queensland Australia has been one of the premier sources for boulder opal in the world. This is an unusual pair of boulder opal doublets. The domed cap is a transparent optical grade of created gem quartz, while the bottom is a slice of natural & untreated Boulder Opal.
Gemstones can look different under different types of light. The redder background images were taken with incandescent house light while the other images used a Daylight LED light source. Sunlight is the best light to view most gemstones. Unfortunately, we rarely have sunlight and blue skies in Maine, so outdoor photos are nearly impossible to take. Our prices are at wholesale. A Gift box is included order with this purchase.
