Jewelry Guide & Care

18k Gold

To prevent damage to your white, yellow or pink gold jewelry, we recommend you store it safely away from other pieces to avoid unnecessary scratches. Gold should be kept away from harsh chemicals, such as cleaning and beauty products, to avoid discoloration to the metal.

All our 18k white gold has been plated with a white rhodium finish, this is a layer of plating applied to the metal to emphasize the bright white finish of the metal and can be especially susceptible to discoloration when brought into contact with chemicals. Should this occur, please contact us at or call us at 516.759.9700, we can offer you a rhodium plating service to bring back that white shine.


Platinum has the advantage of being a harder and a more durable than most wearable metals, however, it needs caring for in a similar way to your gold pieces. It is still prone to scratching so should be suitably stored to prevent it from rubbing against other pieces you may have. Again we would recommend you keep this away from any strong chemicals to avoid damaging or weakening the metal.


Diamonds are well known for their hardness of 10 on the Mohs scale, however they can still be chipped or cracked when knocked and care should be taken to avoid harsh contact when worn. Diamonds can be easily cleaned using a small amount of liquid soap in hot water and dried using a lint-free cloth to remove any dirt and grease to bring back its shine.
