Marriage may be one of life’s major milestones, but for the guys, popping the question can be intimidating. In addition to planning the actual proposal, there’s that small, but crucial detail of an engagement ring. From diamond cuts to setting styles and band types—it’s the details that make for a unique and original ring. But what if you don’t know what your lady wants?

Enter Denver-based jeweler Abby Sparks. Known for her customized approach to fine jewelry, Sparks recently launched the Loaner Ring program. Specifically aimed at the indecisive guy, the procrastinator, or the man who wants his wife-to-be involved with the custom process, the program’s goal is to work with couples to design a ring that she’ll want to wear for a lifetime.

Here’s how it works: When you first contact Sparks’ studio, she’ll schedule an initial consultation—either in person or on the phone—and walk you through the process. Once you decide to move forward, the Loaner Ring functions as a pretty placeholder: You’re lent an Abby Sparks cubic zirconia solitaire set in sterling silver to propose with, along with a ring box, small bottle of Prosecco, two champagne flutes, a box of champagne gummies, and a card explaining the custom design process for the bride (check out Sparks’ step-by-step guide here). Couples are generally ready to begin designing their ring within 30 days of the engagement, although Sparks is flexible on timing. The bride turns in the solitaire once Sparks delivers her final ring.

The Loaner Ring program costs $500—essentially a non-refundable retainer that goes toward the cost of your custom ring. Need some advice planning the actual proposal? Sparks can help there too, with expert guidance on everything from romantic locations to the best florists. Bottom line: If you want to sweep your bride-to-be off her feet with a ring she’ll cherish forever, Sparks’s loaner ring program can ease you into the custom process, minus the fear.
