Yes - Lab grown diamonds, also known as laboratory grown diamonds or ethical lab grown diamonds, are chemically identical to mined diamonds or natural diamonds. They offer the same level of beauty and are an extremely popular choice. A lab grown diamond, unlike a simulant, has the same chemical and physical properties as a mined diamond. They are aesthetically and physically identical to mined diamonds, offering the same fire and brilliance.

Our range of lab grown diamonds are available in round, oval, pear, emerald, radiant, cushion, marquise, elongated hexagon, princess, asscher, heart and elongated cushion. We offer fancy coloured lab grown diamonds in all shapes and sizes.

The only difference between a mined diamond and a lab grown diamond is the origin. Lab grown diamonds are free from the ethical concerns associated with mined diamonds. Lab diamonds are created under high pressure in a laboratory using advanced technology and offer the same fire, clarity, and carat weight as mined diamonds.

We offer a personalised in-person showroom experience to explore gemstone shapes, carat weight, compare engagement ring designs and purchase our ready-to-wear range. Our collection is also available to shop online, with the option to customise a ring unique to you. We provide comprehensive support, with a specialist guiding you through each step of your engagement ring journey.

Cullen Jewellery offers a complimentary Lifetime Manufacturing Warranty on all our products, including lab grown diamond rings, ensuring peace of mind.

Yes - Moissanite is a brilliant alternative to a lab diamond engagement ring. It offers exceptional clarity, durability, and sparkle, making it a stunning gemstone in its own right. Unlike a "fake diamond," moissanite is a high-quality lab grown gemstone that provides the same level of brilliance as a diamond at a more accessible price. Each moissanite stone at Cullen is checked by our expert team to ensure it's the best quality, just like our lab grown diamond collections.

Moissanite engagement rings are becoming increasingly popular due to their beauty, durability, ease of customisation, and affordability. They retain their sparkle indefinitely, with clarity and carat weight remaining intact over time. If you're looking for a timeless, brilliant gemstone that rivals the aesthetic of mined diamonds, moissanite is the perfect choice.

To find the perfect moissanite engagement ring explore our extensive collection of moissanite engagement rings online. For a custom design, schedule an appointment with our expert team, who will guide you through the entire process to ensure you get the perfect ring.

Moissanite and diamonds (both lab grown and mined) share similar optical properties, making moissanite a great alternative to diamonds. Many people mistakenly believe moissanite is a "fake diamond," but it is a unique gemstone with its own beauty and brilliance. To the naked eye, moissanite rings look nearly identical to diamond rings, offering a timeless aesthetic that never appears "tacky" or fake. Due to its comparable thermal conductivity, moissanite can even pass a diamond tester. However, at Cullen Jewellery, we use specialised equipment to distinguish between moissanite and diamonds, ensuring full transparency in your purchase. If you're considering a stunning alternative to a lab grown or natural diamond ring, moissanite is an excellent choice. Explore our collection today to find the perfect moissanite engagement ring for you!
