🧠 FAQ – Lab Grown Diamond Necklaces

Are Lab Grown Diamond Necklaces Real Diamonds?

Yes, lab grown diamonds are real diamonds. They have the same physical, chemical, and optical properties as mined diamonds. The only difference is they’re created in a controlled lab environment instead of deep within the earth.

Do Lab Grown Diamonds Hold Value?

Lab grown diamonds typically do not hold resale value the same way mined diamonds might. However, they offer a more affordable upfront price, and for most buyers who aren’t planning to resell, they’re a smart, ethical, and cost-effective choice.

How Do I Clean A Lab Grown Diamond Necklace?

You can clean a lab grown diamond necklace the same way you would a mined one. Use a mild dish soap and warm water solution with a soft toothbrush to gently scrub the diamond and setting. Avoid harsh chemicals or ultrasonic cleaners unless recommended by the jeweler.
