I just wanted to say a big thank you for your excellent Customer service (Carl) and brilliant craftsmanship & advice (Edward)! I absolutely love my ring – the diamond, design and fit is everything I wanted!! I have so many comments every day and I tell them exactly where and who did it! I look forward to seeing you both in the next 8-10 months to get our wedding bands done. Thank you for everything once again!

Hi Carl & Edward, We are thrilled to let you know that Jarrod popped the question (and I said yes) during our holiday in Africa. I absolutely love the ring – it is stunning and even more beautiful than I anticipated. Thanks so much to both you and Edward for an amazing piece, one which I will treasure for a lifetime. Many thanks

Annette Cameron

Hi Carl and Ed, I just wanted to say a huge thank you to Ed and yourself for all your hard work and being able to complete the ring in time. The finish is amazing and I couldn’t have hoped for a better design and finished piece. Thank you for all your help and advice throughout the process, it made it easy, fun and put me at ease knowing your expertise and high standards you set for yourselves. Tyrolin absolutely adores the ring as well as the little touches such as the saw piece and it fits perfectly! She said she couldn’t have hoped for a better proposal and ring. Many thanks

Hi Carl, ABSOLUTELY OBSESSED WITH MY ENGAGEMENT RING! Daniel & i went through the whole process together with Carl & Edward from sourcing the perfect diamond to designing the ring around our phenomenal diamond. Carl went above & beyond to ensure the diamond was everything i had hoped for and more. Edward spent hours working with us on a unique design just for us, his craftsmanship is out of this world, everyone who’s commented on my ring has said its the best they have ever seen and they’re not wrong Edward’s work is phenomenal and he doesn’t stop until he has created the perfect masterpiece!

Jarrod Alati

Hi Edward and The Team, I have been meaning to write this for some time now and I apologise it’s taken so long. I must say a huge thank you to you for your work on my engagement ring. Your design is exquisite, beautiful, stunning! The list could go on as the ring is truly amazing! I have had so many comments on your design and it is far better than I could have ever imagined.

Kristy Haggett

Hello Carl, I have been meaning to email you since I received my ring from David to tell you how much I love it. Thank you to you and Edward. Thank you also for your frank advice about what size the shoulder diamonds should be, they look wonderful at 0.75ct. The setting is absolutely perfect too. There is not a day that goes by without people commenting. I love it so much, so thank you.

Frequently Asked Questions

What is a fancy colour diamond?

The loose fancy coloured diamonds were among the rarest and most beautiful gems globally. These loose coloured diamonds are prized for their intense visible hue and incredible charm, ranging in colours from yellow to pink to green. Unlike traditional white diamonds, composed of carbon atoms arranged in a perfect crystal lattice, fancy famous coloured diamonds form under more strenuous conditions in a diamond mine, resulting in a slight disruption to the atomic structure. This disruption causes light to scatter differently as it passes through the stone, resulting in the distinctive colours that make these colourful diamonds so cherished.

Are coloured diamonds real?

Yes, different colour diamonds are utterly authentic in every way. Their diamond colour grades result from the minerals and elements that make up the diamond’s composition, and there is no artificial colouring or treatment involved. The colourful diamond can vary from light pink to deep red, blue, green, and purple diamonds, and each one is unique.

What is the rarest diamond colour?

The rarest diamond colour of all is red. Most red loose coloured diamonds display a light pinkish hue; however, stones with a deep red hue are scarce and exceptional. Authentic red diamonds are so incredibly scarce that fewer than 30 have been discovered – making them genuinely priceless famous coloured diamonds.

What is the rarest natural colour found in diamonds?

The rarest colourful natural diamonds are those with the rarest diamond colour like pink, red, orange, purple, and violet. These different colour diamonds make up less than 1% of all the loose fancy coloured diamonds mined each year – making them extremely valuable and challenging to find.
