Every Kyomi jewel is a timeless story of craftsmanship and brilliance. To keep your diamonds, Polki, and solitaires radiant for generations, handle them with care — wear them last after applying perfume, store them separately in soft pouches, and clean gently using mild soap or a soft cloth. Avoid moisture, harsh chemicals, and direct sunlight to preserve their natural glow. For expert polishing, re-foiling, or re-certification, visit your nearest Kyomi or Sulthan Diamonds & Gold boutique.
