A World of Colour in Diamonds
Coloured diamonds offer a bold, personal way to tell your story through jewellery. From soft champagne and rose tones to striking blues, pinks, and yellows, coloured diamonds are available in a wide range of shades — each with its own character and charm.
We offer lab-grown, natural, and treated natural coloured diamonds, so you can explore the full spectrum of colour, rarity, and price to find the perfect fit for your vision.
Lab-Grown Coloured Diamonds
Lab-grown coloured diamonds allow you to enjoy beautiful, vibrant colour at a more accessible price point. Created using advanced technology, these stones are visually and chemically identical to natural diamonds — but made in a controlled, ethical environment.
Key benefits:
- Wide colour range: pink, blue, green, yellow, champagne, and more
- Ethically grown and fully traceable
- Excellent value for bold, expressive designs
- Ideal for bespoke engagement or dress rings
Natural Coloured Diamonds
Naturally coloured diamonds are among the rarest gemstones on Earth. Their hues are created by unique geological conditions over billions of years, and each stone is completely individual in tone and character.
Facts about natural coloured diamonds:
- Exceptionally rare — especially in blue, green, and pink tones
- Among the most expensive diamonds per carat (especially Argyle pinks)
- Highly sought after by collectors and connoisseurs
- Responsibly sourced through certified suppliers
Treated Natural Diamonds
Some natural diamonds are enhanced using safe, permanent treatments — such as irradiation or HPHT — to bring out or add colour. This process creates stunning visual effects while offering a more accessible alternative to rare fancy-coloured diamonds.
Why choose treated natural diamonds?
- Real, earth-mined diamonds with enhanced colour
- Often more affordable than untreated fancy colours
- Great for clients who want a natural diamond with a vibrant look
- Available in pink, blue, yellow, green, and more
We always clearly disclose whether a stone has been treated and help you compare it to both lab-grown and naturally coloured options.
Case Study: A Moment in Fiji
One of our most memorable commissions was a three-stone engagement ring featuring a vivid lab-grown green oval diamond, complemented by two white pear-shaped lab-grown diamonds, all set in platinum.
The design balanced bold, modern colour with timeless elegance — a perfect reflection of Steve and Isabella’s unique style.
Steve proposed to Isabella on the Yasawa Islands in Fiji, surrounded by crystal-clear waters and golden tropical light. The rich green of the centre diamond wasn’t chosen by chance — it was selected to match Isabella’s eye colour, making the moment even more personal and unforgettable.
“What a lovely ring, Neil!! Thank you so much for helping Steve to get it done! It was completely unexpected and a lovely surprise!”
