Love Notes

“Working with Kellie was the least stressful part of the wedding planning experience. I knew nothing about men’s band styles, material, thicknesses, finishes, etc. and Kellie made me completely comfortable with the process. What I enjoyed most was that she guided me in the direction I wanted to go rather than steering me towards something I wasn’t interested in. We finished my process with the perfect ring that my wife would describe as “handsome” and “timeless”. It really fit the vibe I was looking for. Couldn’t recommend her enough!”

“My experience with KSFJ was exceptional. I reached out to Kellie to discuss an upcoming engagement and was looking for the perfect ring. Kellie walked me through the process of selecting a diamond, band, ring type and all of the components of purchasing an engagement ring that I of course had never been exposed to. She was knowledgeable about the market and listened to my thoughts. Her investment in making sure I found the perfect ring made a what can be daunting experience very personable and the result was a ring that came out perfectly.”

“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.”

Fun facts

What do you consider your style to be?

As a client-focused jeweler, the process of personal jewelry design becomes less about my style and more about the couples I am assisting. I take on the role of a guide and build a strong rapport by asking the right questions to discover exactly what my customers envision, even if they don’t have the right words to articulate their wishes or particular jewelry style. From big bling to understated and timeless, I am always eager to bring the perfect jewelry pieces to life and make sure your style is at the forefront.

How did you get started in the wedding industry?

Working in the wedding industry closely followed my journey into fine jewelry. I got my first taste for the industry while assisting a local jewelry designer with her wholesale business. I learned so much from that experience and fell fast and hard for the fine jewelry industry. A short time later, while living abroad, I started my own private buying business and attended international jewelry and gem trade shows which opened my eyes even more to my love of gems (especially diamonds!). After a move to London, I studied design and diamond grading at the Gemological Institute of America (GIA) and started Kellie Stonger Fine Jewelry in 2017 to share my passion through tangible creations that fulfilled my creative purpose and served my clients. I love being a part of such a special time of people’s lives and hope to make the experience as simple (and special) as possible.

What are your favorite kinds of couples to work with?

Are you in love? If your answer is a big “YES!” than I think we will get along great! Jewelry buying is such an intimate experience and I cherish the couples that allow me to assist them in such an important buying decision. Almost all of the clients I work with become dear friends — through the design process we really get to know one another, and I am honored that they trust me to share in a part of their love story and beyond.

What is your favorite part about a wedding?

Being the first stop on the wedding adventure is such an honor and I feel privileged to be part of so many love stories! The thought and emotion that goes into creating and selecting THE PERFECT ring for their person — their forever love — melts my heart…every…single…time. I get to witness such extraordinary moments for both the proposee and the couple. Many people do not get the chance to see this side of their partner and I wish I could bottle that moment up to share with the recipient. I like to think I put the love and sincerity I see during my consultations into the pieces my clients wear.
