When you walk through the Sydney - whether you are browsing the historic displays in the Queen Victoria Building or visiting us on Level 2 of the Strand Arcade - one question comes up more than any other: Should we choose a lab-grown diamond or a natural diamond for our custom engagement ring?
At Cartmer & Co, we believe the perfect ring isn't defined by a marketing trend; it's defined by what matters most to you. Because we specialise in completely bespoke jewellery design, we craft stunning engagement rings using whatever stone fits your vision, your ethics, and your budget.
Book your consultation to view our jewellery Monday to Saturday. If you'd like a CAD Design Consultation for something completely unique, we usually reserve these for weekdays — due to the complexity of design rendering and the time it takes to do it justice. To request a weekday after-hours slot, simply select the last available time on your preferred day and add your preferred time in the notes (e.g. 5:30pm on Thursday) - we will call you to confirm as soon as possible.

What is the Difference?
Natural Diamonds: Formed deep within the earth over billions of years, natural diamonds carry a sense of rarity, tradition, and enduring value. For couples looking for an investment piece with a unique geological history, natural stones remain unmatched. Browse our natural diamond engagement rings for inspiration.
Lab-Grown Diamonds: Cultivated in a laboratory using advanced technology, lab-grown diamonds are optically, chemically, and physically identical to natural diamonds. They offer incredible brilliance and size for a fraction of the cost, making them a highly popular choice for modern couples looking to maximise their budget.
Australian Sapphires: For those looking for something entirely unique to our heritage, we also specialise in sourcing deep, rich Australian sapphires that offer a stunning alternative to traditional white diamonds.

Why Choose Bespoke Over High-Volume Retailers?
Walking into a high-volume diamond showroom in Sydney often means choosing from a pre-made tray of mass-produced designs. When you choose a custom design boutique like Cartmer & Co in the Strand Arcade, you sit down directly with the creators. Whether you prefer a rare natural stone or a modern lab-grown diamond, your ring is engineered and handcrafted individually to tell your specific story.
CAD Design Consultations are reserved for weekdays to ensure we can dedicate the full time and detail your design deserves. For after-hours sessions, select the last available slot on your preferred day and add your preferred time in the notes - we will call you to confirm as soon as possible.
Whether you are drawn to a classic diamond engagement ring, a vibrant Australian sapphire, or a modern lab-grown stone, we bring your vision to life - entirely from scratch, entirely for you.
