From your idea to your hand in about four weeks.

Bring a sketch, a photo, or just a feeling about what you want. Consultations are complimentary.

  1. 1

    Tell us what you love

    Sit down with our designers in the store. Show us a sketch, a reference photo, or a ring you saw once and never forgot. We’ll talk shape, metal, budget and timing.

  2. 2

    See it designed in CAD

    We draw your ring in CAD so you can review every angle, from the band width to the height of the setting, and change anything before it’s made.

  3. 3

    Made in metal

    Your design is cast in the metal you chose and finished by hand. Natural or lab-grown, the center stone is chosen with you.

  4. 4

    Set, polished, and ready

    The stone is set and the ring is polished. Custom pieces typically take about four weeks from start to finish. Have a family stone? We can set your own diamond or heirloom.

Lab-grown or natural? Both are real diamonds.

We carry natural diamonds and IGI and GIA certified lab-grown diamonds in every shape and many price ranges. Our approach is education, not judgment.

Natural

Formed over billions of years in the earth. Chosen for rarity and tradition.

Lab-grown

The same chemical and physical properties as natural, often letting you go larger or higher in quality for the same budget.

Also available: fancy colored diamonds, moissanite, and gemstones including sapphires, rubies and emeralds.
