Opals are rated 5 to 6.5 on the Mohs scale of hardness, meaning that they are somewhat fragile but can be the perfect gemstone for many types of jewelry. For comparison, natural and
lab diamonds rate a perfect 10 on the Mohs scale while
pearls are a 2.5.
Opals can be scratched or chipped if you’re not careful when wearing them. But overall, opal rings, bracelets and necklaces are safe for frequent wear. The right settings can keep opals safe for lasting beauty.
To keep your opal rings in their best shape, avoid wearing them when you’re cooking, gardening, hiking, or engaging in other potentially gemstone-damaging situations. Keep these gems away from harsh cleaners, chemicals or lotions that can damage them.
