Not your mother's jewelry box

Here at Cool Girl Jeweler we specialize in things that will make you say "I didn't know jewelry could look like that." We work with some of the best precision lapidaries in the world to source one of a kind gemstones for our projects, and we believe in embracing the unique and the weird to create jewelry you'll want to live in and be seen in.

Meet Katherine Cappelletti

GIA Graduate Gemologist, Owner and Jeweler

I am an art lover, goldsmith, wife, wobbly cat owner and mom to the baby boy who will forever be my favorite creation. My favorite diamond shape is emerald cut, I think colored-stone engagement rings are underrated, and I've spent my entire life wanting to play with sparkly things, so I do!

I work with a range of techniques including traditional hand fabrication methods, as well as wax carving and casting to bring my pieces to life, and I have a gemstone collection that is at times as out of control. You can see a lot of the gemstones that have caught my attention here!

We're the right fit for each other if you're interested in something bold and color-focused, and ready for your next jewel to feel like nothing you've ever seen before.
