Our Story

 
 
 

Founded in 2017, Kellie Stonger Fine Jewelry is an independent, private fine jewelry studio based in Downtown Littleton and serving the greater Denver, Colorado area specializing in custom design, heirloom redesign, and thoughtfully curated fine jewelry collections. With a highly personalized approach, the studio works closely with individuals and couples to mark life’s most meaningful momentsβ€”through engagement rings, wedding bands, custom and semi-custom pieces, and future heirlooms designed to be worn for generations.

Innovation is also part of the story. KSFJ’s patent-pending Oura-ring jacket β€œThe Smart Cocktail Ring” β€” a luxury diamond cocktail ring designed to house a smart ring β€” was featured in The New York Times Magazine, blending technology with tradition in a way that feels distinctly modern.

At the core of the brand is a belief that fine jewelry should feel intentional, wearable, and deeply personal. Services extend beyond custom creation to include jewelry collection planning, styling services, jewelry box edits, and discreet gifting concierge servicesβ€”offering clients expert guidance at every stage of collecting and wearing fine jewelry.

From proposals and personal milestones to everyday styling and legacy pieces, Kellie Stonger Fine Jewelry serves as a trusted fine jewelry specialistβ€”guiding clients through each chapter with expertise, intention, and enduring design.

Testimonials

Kellie was absolutely incredible to work with from start to finish. Not only does she work to create the perfect piece, she wants to get to know the couple's love story as well. She graciously goes through multiple designs and small tweaks to make sure the piece is everything you dreamed of. She brings her own ideas while listening to exactly what you want - we could not be happier with the final outcome! She always goes the extra mile including fitting us in to have the ring resized in 2 days. We can't wait to continue our relationship while working on our wedding bands!

When it comes to jewelry, KSFJ is the best! Kellie is knowledgeable, creative, and she cares a lot about her clients and the jewelry that she makes for them. The custom engagement ring that she designed with my husband is absolutely jaw-droppingly beautiful! Since then, Kellie has worked with us on our wedding bands, bracelets, and a necklace! I love wearing my KSFJ pieces because I know that they were made with so much love and thoughtfulness.

I had a fantastic experience picking out my fiancé’s engagement ring with Kellie. I was very unfamiliar with the process and Kellie was extremely helpful in educating me about the different options and what my fiancΓ© would like best. She was also great at sourcing the perfect stone and ring that matched exactly what we were looking for and was able to secure it for a great price within our budget. I would highly recommend Kellie to any couples that are looking for the perfect engagement ring!

I walked into Kellie's stunning office space and knew that I was right where I needed to be. I had been unsure of what to do with the precious stones that my late husband had given me: an engagement ring, two wedding bands and a right hand ring. All four of these rings held meaning and memories, yet they also were a symbol of broken dreams and a shattered future. With so much respect and care, Kellie Stronger patiently walked with me through the process of designing a right hand ring that I would cherish for the rest of my days and pass on to my young daughters. Kellie's attention to detail, compassion and excellent taste, made it easy (and fun!) to design this one-of-a-kind ring. I am forever grateful for how she took a symbol of "what wouldn't be" and created the most gorgeous ring that reminds me daily that out of the ashes comes new life.
