One of a Kind, By Design

CUSTOM ENGAGEMENT RINGS

Designed To Be Unique

Every Demirjian custom engagement ring begins with your story, your stone, and your vision. We design it from scratch, build it by hand. When it's finished, it exists nowhere else in the world.

Our Process

Creating Your Engagement Ring

A jeweler shows a 3D computer rendering of a custom diamond ring design to a couple during a consultation appointment.

CONSULTATION

Your first conversation is with directly with Garo Demirjian. We review your inspiration together, discuss diamonds and gemstones, walk through metal choices and setting styles, and establish a clear budget and timeline. Every question you have gets answered here.

INSPIRATION

Start by collecting photos, screenshots, drawings, and anything you've seen. Styles you've admired and ones you haven't. What you don't want is as useful as what you do. Think about metal preference, stone type, and shape. The more you bring to the table, the more precisely we can design your ring.

CAD DESIGN

Using your input, we create detailed 3D renderings of your ring from every angle. Proportions, setting style, stone placement, all of it is visible before a single piece of metal is touched. We refine until the design is right.

PROTOTYPING

From the approved CAD, we produce a physical 3D printed scale model of your ring. You can wear it, feel it and see the proportion on your hand, and confirm every detail before fabrication begins. This is the step that eliminates surprises.

FABRICATION

Once approved, your ring enters production. Cast, set, and finished by Garo Demirjian master craftsmen. Every diamond and gemstone is hand-selected for quality and brilliance holding the Demirjian quality standards.

WHAT WE CREATE

FIND YOUR STARTING POINT

Every piece starts with a conversation and gets built entirely by hand in our workshop.

Custom Engagement Rings

Every engagement ring starts from zero. Stone selection, setting style, band width, metal, proportion — all decided together. You approve detailed renderings before we touch any metal. The result is a ring built specifically for this moment.

Custom Wedding Bands

A wedding band should be designed alongside the engagement ring it lives with. We craft bands that integrate seamlessly with your existing ring or stand on their own. Hand-finished, always original.
