Build your own Bracelet, Anklet, or Necklace

Minimalist white heart design with a continuous line on a black background.

Step 1: Choose a Chain

The backbone of your new jewelry box staple.

Coastal Carats is your one stop shop for truly custom, bespoke jewelry pieces. Our “build-your-own” jewelry bar starts with the chain. Our thin paperclip chain whispers “everyday classic,” while our adorable heart link chains are perfect for a mother’s day gift or matching besties necklaces. With metal choices that fit every lifestyle and budget, once the base feels right, everything else just clicks. And every chain is cut to the exact length of your choice, so there’s no waste.

Step 2: Choose a Charm

Where you can REALLY let your personality sparkle

Our favorite part of the Coastal Carats experience— with your chain locked in, you can now layer on color, gemstones, letters, and anything else that you can imagine. We mix lab-grown diamonds, ethically sourced natural gemstones, and reclaimed vintage finds. Every piece tells a story that’s both luxurious and sustainable, and designed to outlast your every day life— including going to work, the gym, and—of course—the beach!

Step 3: Choose a Clasp

The final touch to lock in your look.

You nailed the chain and the charm— now it’s town to lock things down with a clasp. Whether you prefer our in-person welded permanent jewelry experience or want a more classic clasp for the versatility, this step makes your Coastal Carats piece ready for real life.
