Description
These calibrated 7 × 5 mm opals are prized for their soft, luminous milky-white body color, which creates a bright, elegant backdrop for a striking play of color. The gentle white base enhances the opal’s glow and makes the spectral flashes stand out beautifully—resulting in a classic, high-end opal look.
The stones show a lively play of color, with vibrant flashes that dance across the surface as the opal is moved. With an average weight of approximately 0.55 ct per stone, they are substantial enough for premium designs while remaining perfectly suited for calibrated settings. Their consistent dimensions make them ideal for rings, earrings, or matching sets where uniform sizing is essential.
Please note: the price is per single opal. Images may show several opals together to communicate the average quality and appearance of the stones. You can purchase one piece or multiple stones—perfect whether you need a single center stone or a calibrated selection for your design.
