When Christina Applegate said “I do” with Martyn LeNoble in Los Angeles on Saturday, she not only added a new member to her family, but also a new piece of jewelry to her collection.

Neil Lane, who tells PEOPLE the piece “is not a typical ring,” designed the actress’s new sparkler.

Lane explains of the bauble, “It has a border of diamonds around it like a sleeve. We took her engagement ring and fit it in a sleeve of little diamonds to become one with the wedding band. It’s platinum and diamond inset with tiny little diamonds everywhere.”

As for the very intimate nuptials — which only about eight people attended, including the couple’s daughter Sadie and LeNoble’s daughter Marlin — Lane says, “It was just the right time. They’re a very happy couple. There is a great deal of love between them.”
