AJ Gem & Jewellery — Sparkle That Defines You

Cut with intention.
Set to last.

Ethically sourced gemstones and heirloom-grade settings, handled by our own workshop from rough stone to finished piece. Fine jewellery, made to be worn for generations.

"Every stone we set has already survived a hundred million years. We treat the setting with the same patience."

Our Story

A workshop built on patience, not shortcuts

AJ Gem & Jewellery began with a simple standard: never sell a stone we wouldn't set for our own family. That standard still shapes every piece that leaves our workshop today — from the sourcing table to the final polish.

We work in small batches and take on bespoke commissions precisely because fine jewellery shouldn't be rushed. Each gem is graded, matched, and set by hand, with full transparency on origin and cut.

Craftsmanship

From rough stone to finished piece

Four stages, every one done under our own roof.

01

Sourcing

We select rough and cut stones directly from vetted mines and cutters, verifying origin and ethical provenance before anything enters the workshop.

02

Cutting & Grading

Each gemstone is graded for clarity, colour, and cut precision, then matched to the design it was chosen for.

03

Setting

Our goldsmiths hand-set every stone, checking tension and alignment under magnification before a piece ever leaves the bench.

04

Finishing & Polish

A final hand-polish, quality check, and certification round out the process before the piece is packaged for you.
