Opal – Buyer's Guide
Buyer Intro
Buyers should review play-of-colour brightness, pattern, body tone, and whether the piece will be worn with enough protection for the gem's relative softness.
Colour Guide
Focus on overall colour character, tone, and how evenly opal faces up once set in jewellery.
Clarity Guide
Review transparency, visibility of inclusions or texture, and whether the internal character suits the category and price level.
Cut Guide
Assess whether the cut supports brightness, balance, and the visual personality that buyers expect from opal.
Carat Guide
Compare apparent size together with cut proportions rather than carat alone, especially where deep cuts or lighter tone can affect the face-up look.
Price Factors
Price is usually shaped by colour, size, clarity, cut quality, rarity, treatment disclosure, and the strength of market demand for opal.
Rarity
Rarity should be explained in context: fine examples of opal are rarer than commercial goods, but availability still varies by quality band.
Daily Wear
Daily-wear score: 5/10. Ring suitability is rated as moderate, while earrings and pendants are rated excellent and excellent respectively.
Buying Tips
Ask for clear treatment disclosure, compare multiple stones side by side where possible, and match the purchase to the final design and wear expectations.
Warnings
Do not treat opal as a one-size-fits-all category; treatment, identity, and durability should be explained before quoting final value or care advice.
