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.

The Toi et Moi ring, translating from French as “you and me”, is one of the most historic ring setting styles that symbolises love stories and partnerships. This style first gained attention when Napoleon Bonaparte gifted his wife Josephine de Beauharnais a Toi et Moi with a diamond and sapphire in 1796.

Yes, we can create a two-tone Toi et Moi engagement ring! Choose from Platinum, Yellow Gold, Rose Gold and White Gold.

And, because it is made just for you, a custom ring is truly a reflection of your love story. So, if you're looking for an engagement ring that is as special as your relationship, consider designing an engagement ring with our support throughout the whole process. It will be a symbol of your love that you will cherish forever.

There are many reasons to create a custom-designed engagement ring. Perhaps you have a specific style or have always had a dream ring in mind. Maybe you simply want to add a personal touch that will make the ring even more special. Whatever your reason, collaborating with a designer to create a bespoke engagement ring is an incredibly rewarding experience. You'll be able to choose every aspect of the design, from the type of metal to the cut of the stone, with Cullen Jewellery's support throughout the entire process and your final approval.

For inspiration, our design specialists will ensure that you only receive the highest quality advice. Individually designed with a lifetime guarantee, our bespoke engagement rings only use ethically sourced lab grown diamonds or moissanite that you can wear in style. Picking a gemstone that suits your perfect ring is crucial. The first step is to choose the lab grown diamond or other precious stone that will be the centre stone. For instance, if it is a lab grown diamond ring, we will work with you to bring your lab grown diamond engagement ring design to life. Several factors are relevant to your dream engagement ring, including diamond shape, carat weight, and jewellery design. Our bespoke design process ensures you will receive the perfect engagement ring. You can check out our full range before you decide on your perfect design, and we also offer wedding bands in yellow gold, white gold, rose gold, and platinum.
