Frequently Asked Questions

This is a myth! Opals were actually considered symbols of hope, purity, and truth in ancient times. The superstition arose from a 19th-century novel and has no basis in fact. Opals are beautiful gemstones that bring joy to their wearers.
Real opals display a unique play-of-color that changes with viewing angle. They feel slightly warm to touch and have natural inclusions. Synthetic opals often show too-perfect patterns. For valuable pieces, always get certification from a reputable gemological laboratory.
While opals can be worn daily with proper care, they're softer than diamonds (5.5-6.5 on Mohs scale). Choose protective settings like bezels for rings, and avoid wearing during activities that could damage the stone. Pendants and earrings are excellent for everyday wear.
Solid opals are 100% natural opal. Doublets consist of a thin layer of opal glued to a backing (usually black). Triplets have an additional protective cap (usually quartz or glass). Solid opals are most valuable, while doublets and triplets offer affordability.
Opal prices vary dramatically based on type, color, pattern, and size. White opals can start from £50 per carat, while exceptional black opals can exceed £10,000 per carat. Boulder and crystal opals fall in between. Quality and rarity are the main price factors.
Most solid opals don't need to be stored in water. However, if you have Ethiopian opals (which are hydrophane) or live in very dry climates, occasional moisture exposure can be beneficial. Never store doublets or triplets in water as this can damage the adhesive.
