Have you been wondering how to shop for a loose diamond— whether you are considering a loose diamond as the start of an engagement ring, to upgrade an existing piece of jewelry, or for another design entirely? 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.

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.

"Usually you only hear about customer's loyalty to a business, but never the other way around. This all changed with Affinity where for the first time, I experienced loyalty from a business I have patroned. 

Per my previous review, my husband and I had a great experience buying both of our wedding bands here. Fast forward 4 years later and my husband's wedding ring slipped off his finger while surfing. I called them asking to re-order it, and they offered a discount due to the circumstances of the situation. I had no expectation of that, and was completely taken back at their thoughtfulness. 

They had everything in our records, so re-ordering the ring was a breeze and completely stress free. I'm almost grateful for the experience of needing to re-order because I saw even more of their integrity and love for their customers and it blessed me so. It doesn't get any better than this folks!" — Grace B. on Yelp
