Care Tips for Marquise-Shaped Stones

To keep your loose marquise cut lab diamond looking radiant and secure:

• Protect the Points: The two pointed tips of a marquise cut are its most vulnerable areas. Ensure your custom setting incorporates protective V-prongs to shield the sharp ends from hard impacts.

• Clean the Under-Side: Dust and skin oils easily accumulate underneath an elongated stone. Soak the piece in warm water with a few drops of mild dish soap, and use a soft toothbrush to gently clear away residue.

• Safe Storage: Always store your loose stone or finished marquise jewelry in a soft, fabric-lined pouch away from other jewelry to prevent it from scratching other items or being scratched.
