What to avoid with moissanite?

Bleach, chlorine and ammonia have no effect on silicon carbide, but they corrode the metal around it. Chlorine pits and weakens gold over time, particularly the alloys used in 9k and 14k bands. Bleach attacks the rhodium plating on white gold and can leave a yellow shadow under the head. Hot tubs and chlorinated pools deliver continuous exposure, so even short visits add up. Remove the ring for cleaning, swimming and hands-on garden or pool work. The stone itself can take harsh treatment, but the prongs holding it in place cannot, and a weakened prong is how stones get lost.

Moissanite quality varies more than diamond because there is no universal grading authority. Most generic moissanite ships without third-party certification, which makes it hard to compare two listings side by side. Charles & Colvard's Forever One was the original branded premium grade and remains the most consistently graded option, with IGI reports on stones above one carat. Look for a stated colour grade, a stated clarity grade and a returns policy of at least 30 days so you can check the stone in real lighting, including direct sunlight. Prices well below typical 2026 levels around AU$500 to AU$900 for a 1ct stone usually signal a lower grade.
