Explore distinctive pieces for proposals, celebrations, milestones, and everything that follows.

A gemstone that changes with the light

As Unique as the Story It Represents

Alexandrite is loved for its remarkable shift between cool daylight tones and warmer purple-red evening hues. Choose your preferred size, cut, color, metal, and setting to create a piece that feels entirely your own.

Designed with you, not just for you

Your Idea, Brought to Life

Begin with a sketch, an inspiration image, or simply a feeling. Our team guides every decision from stone selection to final inspection.

  1. Share Your Vision

    Tell us your style, gemstone, metal, budget, and the story behind the piece.

  2. Select & Approve

    Choose your center stone and review a detailed CAD design before production.

  3. Crafted for You

    Our jewelers create, set, polish, inspect, and prepare your finished piece for delivery.

Three generations. One purpose.

Craft With a Past—and a Future

Our jewelry studio was established in Wuzhou in 2018, building experience in gemstone cutting, jewelry design, and manufacturing for international clients. Abbett was founded in Hong Kong in 2024 to bring that expertise directly to customers through thoughtful craftsmanship, modern CAD design, lab-grown diamonds, and extraordinary colored gemstones.
