Our Gemstone Collection

Thirteen Gemstones. One Studio.
Every Piece Crafted to Order.

Each gemstone is available as rings, earrings, necklaces, pendants, and bracelets — crafted to order with full certification.

Custom Design

Bring a brief, an image, or simply an idea. We will walk you through stone options, setting styles, and metal choices, and build the piece from your first conversation to the final polish.

Engagement Rings

We design and craft engagement rings to order at our Burnside studio. You work directly with our jewellers on every detail. Complimentary consultations available by appointment.

Repairs and Restoration

Bring in your piece and we will assess it honestly, tell you what it needs, and explain what we can do. We work on pieces from our own studio and on heirloom jewellery from elsewhere.

Online Orders

You do not need to visit the studio to commission a piece. Send an enquiry with your brief and budget, and we will guide you through stone selection, design, and delivery entirely online. Nationwide shipping available across Australia.

Our Story

Swiss Precision. Australian Craftsmanship. Two Generations of Trust.

Coloured Gemstones Australia was founded over 65 years ago by Swiss master jeweller Bruno Moser. Today, as a second-generation family studio in Burnside, South Australia, we continue the tradition he built — combining European precision with Australian craftsmanship.

Every piece is crafted to order. Every stone comes with full certification. And every customer works directly with our jewellers, not a sales team.

Multiple national Designer of Dreams Awards and the 2024 SA Bridal Industry Association title of Best Ring Manufacturer — a standard we hold on every piece.

Certified Gemstones

Every coloured gemstone comes with full grading certification. We walk you through cut, colour, clarity, and carat in plain language so you decide with complete confidence.

Responsibly Sourced

All stones are conflict-free and responsibly sourced. We also work with lab-created stones that offer the same brilliance with full transparency on origin.

Bespoke from the Start

You work directly with our jewellers from the first conversation to the final polish. Your ideas guide every decision — stone, setting, and metal.

Complimentary Consultation

Not sure where to start? Visit our Burnside studio for a no-obligation consultation. Bring ideas, a reference image, or simply a sense of what you're looking for.

Lifelong Care

Professional cleaning, safety inspections, and resizing whenever needed — so your piece looks and fits as beautifully as the day it was made.

Engagement Rings

Designed and Crafted to Order at Our Burnside Studio

Whether you are drawn to a coloured gemstone centre stone, a diamond, or a combination of both — your engagement ring is designed and made in our studio from the first sketch to the final polish.

You work directly with our jewellers. Not a showroom assistant. Not a catalogue. A jeweller who knows the stone in their hand and the craft behind every detail.

Discover the World's Finest Gems with Coloured Gemstones Australia

At Coloured Gemstones Australia, we find the most beautiful natural gemstones from around the globe and craft bespoke jewellery that showcases these extraordinary treasures.

Every gemstone tells a story. Their colours and crystal structures vary by region, shaped by the earth over millions of years. From Sri Lanka’s prized Ceylon sapphires to Burmese rubies, Colombian emeralds, Brazilian amethyst and aquamarine, Australian opals, and Pakistani peridot, we seek out stones with exceptional colour, clarity, and character to make the most stunning coloured gemstone rings and jewellery .

What sets us apart:
– Our commitment to quality and rarity. Many sources are diminishing, and the finest stones are becoming increasingly scarce. This makes each piece not only beautiful but also a valuable investment.

We offer expertise, transparency, and a true appreciation for the gem itself. Our designs are tailored around the stone, ensuring every creation is as unique as the person wearing it.
For rare natural beauty and the artistry to match, Coloured Gemstones Australia is your trusted destination for gemstone engagement rings and high quality jewellery.
