How Opal Quality Is Graded

Opal value is mainly determined by the 4Cs + Origin, with emphasis on play-of-color:

Play-of-Color

• Most important quality factor

• Brighter, broader spectrum & multi-directional colors = higher value

• Patterns like harlequin, flash, flagstone are premium qualities

Body Tone

• Black Opal (dark body tone) shows the strongest contrast and is most valuable

• White/crystal Opal has lighter tones and is comparatively affordable

Clarity

• Eye-clean stones (few or no inclusions/cracks) are more valuable

• Hydrophane (especially some Ethiopian opals) can change appearance when wet — a care consideration

Cut & Shape

• Well-cut cabochons with balanced thickness, symmetry, and polish will display color play better

• Larger stones with strong play-of-color are rarer and command higher prices

Origin

• Australian Opals (especially Lightning Ridge black Opal) — most prized

• Ethiopian and Mexican Opals — beautiful but usually lower price tier

Typical Price Ranges (Per Carat)

Note: Prices vary widely by quality, origin, certification and market demand.

Ultra-premium black Opals from top Australian sources can exceed ₹1,50,000+ per carat or even much higher for spectacular specimens with strong red flashes and rare patterns.

Notes on Pricing

Large vs Small

• Size usually increases price, but quality matters most — a small vivid stone can be worth more than a larger dull one.

Certification

• Always ask for a gemological report from a trusted lab (like GII, GSI, GJSPC — especially for higher-value Opals — to verify natural origin and quality.

Set vs Loose

• Finished jewellery with good craftsmanship and precious metals adds metal + labour markup on top of the stone value.

Quick Buyer Tips

✔ Inspect color play under multiple lights before buying.
✔ Ask if the Opal is natural, treated, doublet or triplet — treatment affects value.
✔ Be cautious of too-good-to-be-true pricing, especially online.
