✨ Care & Maintenance Guide
Every piece in our collection is engineered from premium precious metals and hand-set stones. To preserve its blinding, mirror-like luster and guarantee a lifetime of brilliant wear, please observe our elite luxury care metrics:
* Avoid Harsh Chemical Exposure: Always remove your jewelry before entering chlorinated pools, hot tubs, ocean salt water, or when handling household cleaning agents.
* Apply Cosmetics First: Allow colognes, perfumes, hairsprays, body lotions, and oils to fully dry on your skin before putting on your jewelry. Chemicals in fragrances can prematurely dull precious metal plating.
* Daily Wear Protection: To shield your jewelry from excessive friction and impact, remove your pieces before high-intensity workouts, gym sessions, or sleeping.
* Cleaning Your Metals & Gemstones: To safely lift dust and skin oils, gently wash your jewelry using warm water, a drop of mild, chemical-free dish soap, and a soft-bristled baby toothbrush. Rinse thoroughly and pat dry with a clean, lint-free microfiber cloth.
* Premium Storage: When not in use, store your piece in a cool, dry jewelry pouch or box away from direct ambient moisture and humidity to completely preserve its pristine finish.
