Choosing and Valuing Natural Precious Opal Stones
To evaluate and choose a loose precious opal, buyers must understand the primary value factors. The background darkness, or body tone, is the foundation, with darker body tones (such as black and dark opals) making colors appear more intense and command higher prices. The play of color brightness is equally critical; a brilliant stone displays intense fire even in dim, indoor lighting conditions.
The spectral color range also dictates value, with red being the rarest and most expensive hue, followed by orange, green, and blue. To find comprehensive tips, please consult our how to buy Australian opals technical guide to learn about patterns and body tone scales. Whether sourcing for custom jewelry or building a long term collector portfolio, our ethically sourced, hand selected loose stones offer exceptional quality and value.
