  • An experience worth telling people about

Most jewelry is designed for everyone. Yours shouldn't be.

Jewelry as Personal as the Story Behind It

Custom jewelry doesn't have to feel complicated. Here's what working with Jonathan actually looks like:

Consultation & Inspiration

No.

01

You share your vision, inspiration, lifestyle, and budget. Jonathan listens first, asks the right questions, and begins to shape an approach around what matters most to you. 

Design & CAD Modeling

No.

02

Jonathan sketches the concept and builds it out in CAD, giving you a precise 3D rendering of your piece before anything is cast. You'll see exactly what you're getting and have the opportunity to refine it.

Your Approval

No.

03

Nothing moves forward until you love it. Once the design is approved, Jonathan sources materials, often passing along savings when he's able to secure a better price.

Book a Consultation

Casting & Finishing

No.

04

Your piece is cast, set, and finished by hand. Every detail is reviewed against the original design before it ever reaches you.

Delivery

No.

05

Your finished piece arrives ready to wear and ready to be passed down. Most custom projects are completed within several weeks, depending on complexity and materials.

Frequently Asked Questions

Every design is different, so pricing depends on materials, complexity, and stone selection. Jonathan works across a wide range of budgets and will always be upfront about what's achievable before any work begins. The inquiry form asks for a budget range to help make your consultation as productive as possible.

Timelines vary by project, but most custom pieces are completed within several weeks after the design is finalized. Jonathan will give you a realistic timeline at your consultation.

Absolutely. Repurposing family stones and heirloom pieces is one of Jonathan's specialties. If you have something you'd like to incorporate, bring it to your consultation.

That's completely normal, and it's a great place to start. Jonathan's job is to help you figure it out. Bring inspiration images, a general style direction, or just a feeling. He'll take it from there.

Jonathan works in white gold, yellow gold, rose gold, and platinum, with access to GIA-certified natural and lab-grown diamonds, colored gemstones, sapphires, and more.

Absolutely. Custom necklaces, bracelets, pendants, men’s rings, gemstone jewelry, and more are all available.

“Jonathan K is a brilliant artist! He created a beautiful necklace replicating my husband's badge. The detail in this piece is unbelievable! Such a treasured piece of jewelry honoring my husband's law enforcement service. I highly reccomend him!”

- Kathleen

“I had the greatest experience working with Jonathan! He's such a great guy and put me at ease when discussing buying an engagement ring, which can be a little stressful for some of us.

For someone with zero experience buying jewelry, he made the process so simple. He took my budget and vague ideas for an engagement ring and designed a ring more beautiful than I could've imagined for my (now) wife.

I am so happy that I didn't just pick a ring "off of the shelf," knowing that her beautiful ring is unique for her means so much, and she doesn't mind the consistent compliments she gets on her ring either.”

- T.M.

“Jonathan is amazing! My fiancé and I had a vision of what we wanted our custom ring to look like, we brought it Jonathan and he created an absolutely stunning piece. We knew we wanted a specific type of diamond (Old European Cut) and we was able to get 3 different ones for us to choose from. We brought some pictures of what we liked and he worked his magic and created a 3D CAD drawing and print of the ring. So cool! He was patient with us and once finalized he brought the whole thing to life. Fantastic! I would recommend Jonathan in a heartbeat!”

- Virginia

“Had a beautiful ring to MY style!

Used my Grandmother's diamonds that I wear happily every day. Many thanks for realizing my dream.”

– Abbie
