Our Process
CAD Design
Designing your perfect ring begins with collaboration. During a private consultation, we explore your ideas, preferences, and lifestyle to create a design that feels both personal and lasting.
Using CAD (Computer-Aided Design), we transform your ideas into detailed renderings that showcase your future ring from every angle. This technology allows for adjustments to scale, setting, and proportion before casting begins, ensuring precision and confidence in every detail.
Your Diamond or Stone
Learn about the 4 C’s—cut, color, clarity, and carat weight—in a relaxed, educational setting.
Compare natural diamonds and a range of fine colored gemstones such as sapphires, emeralds, and rubies.
Understand brilliance, sparkle, and proportion as we guide you through each selection.
Receive trusted, transparent advice from experienced jewelers who value craftsmanship, ethics, and quality.
Custom Design & CAD Renderings
Once you’ve chosen your center stone, we refine your design with precision and artistry. Whether you’re drawn to a classic solitaire, a vintage-inspired halo, or a contemporary three-stone ring, our CAD renderings provide a lifelike preview before your ring is made.
We review every angle together, ensuring harmony in shape, symmetry, and structure. This stage transforms your vision into a tangible plan, ready for casting and hand-finishing.
Finished Ring
Your final design, brought to life!
When your design is complete, our craftsmen bring it to life in your chosen metal—platinum, yellow, white, or rose gold. Each ring is meticulously polished and inspected for quality, comfort, and long-term durability.
When you see your finished engagement ring for the first time, it will embody both artistry and emotion—a piece that feels unmistakably yours.
"My engagement ring is truly perfect.
Somehow Lauren and my fiancé were able to design and create the ring
of my dreams without me even knowing what I wanted myself."
