If you are building your ideal engagement ring, looking to upgrade an existing piece of jewelry, or creating another piece of jewelry entirely, you might be interested in how to buy a loose diamond. There’s no denying it— nothing compares to the brilliance and fire of a loose diamond. By purchasing a loose diamond apart from a setting, you are able to get the best look at the stone to really see the 4 C’s— cut, color, clarity, and carat weight— up close. You can view inclusions that a setting might otherwise hide or distract from, allowing you to make an informed decision about the diamond you are investing in.

At Lozano’s Diamond Jewelry, we are happy to offer our customers an extensive collection of loose diamonds, including different diamond shapes from round brilliant, princess, oval, cushion, and radiant cuts, to different fancy color diamonds. We have an abundance of online resources to help our customers explore loose diamonds online, and we invite you to visit our team into our Westlake Village showroom to experience our full diamond selection and find your perfect match.

Never going to another jeweler again!

I called around for pricing for rings for my wife & I. After speaking to a few places, I felt my budget wasn’t enough. I found LOZANO’S in Thousand Oaks (which I drove all the way from Van Nuys to find) because not only was their pricing amazing, but they made me feel valued and important after only 1 phone call!

I entered the shop and was assisted immediately. Extremely affordable & legitimate! All rings had serial numbers & documents along with them.

Thank you so much to Lozano’s for your patience, value & assistance. I couldn’t be happier with this experience.
