What Makes an Exceptional Opal?
- Not all opals are created equal—exceptional opals display a captivating play-of-colour, shifting between flashes of green, blue, orange, and violet as they catch the light. A high-quality opal will have a vibrant, even distribution of colour across its surface, a clean cabochon cut, and minimal visible inclusions or cracks.
- The base tone—ranging from milky white to inky black—also affects rarity, with lighter stones like this one prized for their clarity and internal fire.
- Opals over 2 carats in a single setting, especially when finely set in 18K gold, are rare finds—making this piece both a visual delight and a collector’s investment.
