About Us

Cool Diamonds was born in 2010 with one mission: to make fine jewelry fun again. What started as a one-person obsession with diamonds, pop culture, and clean design has grown into a bold, inspirational brand rethinking what “everyday luxury” looks like.

We mix serious craftsmanship with a not-so-serious attitude—because we believe diamonds and gemstones shouldn’t be locked away in vaults or saved for someday. From iconic charms to minimalist staples, every piece is designed to excite, made to last, and cool enough to wear on repeat.

Proudly based in New Jersey and handcrafted with care by our expert jewelers, Cool Diamonds pieces are designed to be the iconic staples your wardrobe didn’t know it needed.
