Lab-Grown vs. Earth-Grown Diamonds

What’s the difference between lab-grown and earth-grown diamonds? At Gennaro Jewelers, we break it down clearly: cut, clarity, sparkle, value, and long-term considerations, so you can choose the diamond that’s right for you.

For over 100 years, we’ve helped Long Island families make confident decisions with honesty and transparency.
