Kundan jewelry is known for its beautiful and unique handmade designs, but you must handle it carefully to avoid causing damage. Kundan jewelry is made of 24 karat gold, with gold foil wrapped around its frame to support gemstones. A Kundan piece is coated with refined gold -- which is known as the "kundan" -- in spots to affix stones and give it clean edges. Pure gold is a soft substance, so if you need to clean your Kundan jewelry, you must do so carefully and with the proper substances.
Wipe the jewelry with a suede cloth to remove surface dirt and oils. Use gentle motions; rough rubbing may damage the piece.
Use a common pencil eraser to remove stubborn black marks. Gently rub the eraser on dark spots on the piece. Don't apply heavy pressure.
Contact a local jeweler for a professional cleaning if the piece is still dirty. Professional help may be necessary because Kundan jewelry is very delicate.
