Hi, I’m Catherine —

The sparkle behind Coastal Carats.

Broadcasting from the dreamy shores of the Jersey coast, I’m your personal jewelry curator, gem hunter, and custom jewelry pop-up hostess. When I’m not chasing my two littles—George (3) and Little Baby Catherine aka LBC (1)—I’m living my best vintage-pink, beach-club-princess fantasy while sourcing timeless diamonds for your next signature piece.

Coastal Carats is where everyday luxury meets custom creativity. Think: dainty floating diamonds, bespoke charms, and welded jewelry made just for you—right on the spot. From sourcing high-clarity lab-grown stones to curating heirloom-quality gold chains, every Coastal Carats piece is designed to feel as personal as your favorite love letter (but shinier).

We believe in the power of personalization and the joy of jewelry that tells your own, personal story. That’s why we specialize in:

  • Custom fine jewelry made-to-order with lab made, ethically sourced, or vintage diamonds

  • Floating diamond and fancy-cut gemstone charms drilled in-house for a clean, minimalist look

  • Build-your-own welded bracelets, anklets, and necklaces—crafted at pop-up experiences and permanent jewelry parties

  • Mobile charm bar events hosted across Monmouth, Ocean, and the surrounding Tri-State area

Whether you’re stacking charms with your bridal party, choosing your everyday forever chain, or treating yourself to a little treat, Coastal Carats makes sure your jewelry is as unique as your beach day ritual.

So come find me at a pop-up near you, or stay awhile online and explore custom creations built to last long after your tan fades. Because around here, we don’t wait for special occasions—we create them.

With East Coast love and a little glitter,

Catherine Peck
