Our Gemstones

Finding the perfect centre piece for the ring opens up a world of possibilities. We're here to bring all of those possibilities to you, help you explore them and ultimately source your perfect gemstones. Some of our most popular options are included below. We'd also love to hear from you if you have something else in mind.

Lab Grown Diamonds

Our most environmental and sustainable option are lab-grown diamonds, real certified diamonds that are grown in cutting edge laboratories. They start life as a ‘seed’, a tiny fragment of diamond that grow through a combination of a complex mix of gases, high temperature and pressure causing the diamond to grow, atom-by-atom, until a perfect gemstone as good as any mined diamond is formed.

These are quickly becoming our most popular choice with our customers citing their advocacy of sustainability as well as a desire for larger, more impactful stones within their budget.

Mined Diamonds

The classical centre to an engagement ring for decades. For those that appreciate the miraculous process of a diamond naturally developing in the earths crust over millions of years.

Our mined diamonds are ethically sourced, certified conflict free and complete with a diamond grading certificate from GIA.

Coloured Diamonds

More than 300 diamond colours have been identified in an infinite number of shades. The most popular colours for diamonds include red, pink, orange, yellow, green , blue, violet, purple, chocolate, grey, champagne, cognac and black.

Naturally occurring coloured diamonds are much rarer than colourless ones with approximately 1 in 10,000 mined diamonds considered a coloured diamond.

Coloured diamonds can also be grown in a lab following special treatment.

Coloured Gemstones

If you are looking to add colour to your ring, coloured diamonds can often require a more significant budget. An equally stunning alternative is to use another precious gemstone such as ruby, sapphire or emerald.

Sapphires are known for their deep blue colour, however they actually come in a variety of colours. A lesser known fact is that rubies are simply red sapphires.
