Lab grown sapphires are marvels of modern science, created in controlled environments that replicate the natural processes of mined sapphires. They share the same chemical composition, crystal structure, and physical properties as their mined counterparts. So choosing a lab grown sapphire is definitely the responsible choice!

Our lab grown sapphires are crafted using the Czochralski process. This involves melting aluminium oxide and inserting a rod with a seed crystal. As the rod is gently rotated and pulled, a stunning column of sapphire emerges, ready to be cut, polished and transformed into your next cherished piece.

At Cullen Jewellery, we offer an exquisite palette of lab grown sapphires in blue, pink, purple, and red. Trace elements like iron, titanium, and chromium influence the vibrant hues of each sapphire.

Lab grown sapphires offer brilliant benefits. They are more cost-effective and free from the ethical concerns tied to mining. Plus, they boast fewer inclusions and more consistent colour, making them a responsible choice for conscientious jewellery lovers.

Thanks to their impressive durability, our lab-grown sapphires are perfect for everyday wear. Clean them with warm, soapy water, ultrasonic cleaners, or steam cleaners. To keep them pristine, store them separately to avoid scratches from harder gemstones like diamonds.

Lab grown and mined sapphires are identical twins in terms of chemical composition, crystal structure, and physical properties. The key difference is their origin: lab grown sapphires are born in controlled environments, while mined sapphires are formed over millions of years in the Earth's crust.

Our lab grown sapphires boast a hardness of 9 on the Mohs scale, making them incredibly durable and scratch-resistant—ideal for jewellery that stands the test of time.

Absolutely! Cullen Jewellery offers a stunning range of lab grown sapphires that can be seamlessly incorporated into your existing jewellery designs. Whether you need loose stones or completed pieces, we've got you covered.

Sapphires and rubies are both members of the corundum family. The primary distinction lies in their colour: sapphires typically exhibit blue hues, while rubies are renowned for their rich red shades, courtesy of chromium.

Cullen Jewellery’s lab grown sapphires are meticulously eye-clean, meaning they have no visible inclusions. Available in a variety of vibrant colours, each sapphire is carefully checked by our in-house experts to ensure it meets our highest standards of quality and brilliance.
