Your 14k gold garnet and diamond necklace is crafted to last a lifetime with proper care. Here are some best practices:

Avoid harsh chemicals – Remove your necklace when applying lotion, perfume, or sunscreen, and avoid exposure to chlorine, salt water, and household cleaning products, as these can dull the gold and gemstone over time.

Wear with care – While garnet ranks around 6.5–7.5 on the Mohs scale and is suitable for jewelry, it can still scratch or chip with impact. It’s best to remove your necklace during workouts, swimming, or any activities where it may be knocked or pulled.

Store it safely – When not wearing your necklace, store it separately in a soft pouch or lined jewelry box to prevent scratching, especially from harder gemstones like diamonds, sapphires, or rubies.

Clean it gently – Avoid ultrasonic or steam cleaners, as heat and vibration can loosen the setting over time. Instead, use lukewarm water, mild soap, and a very soft brush or cloth.

Professional maintenance – Have your piece inspected and professionally cleaned every 6–12 months to ensure the stone remains secure and everything stays in beautiful condition.
