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! Thank you both so much!!

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 are the most precious gemstones?

The most precious gemstones for jewellery are coveted for their hardness & durability, rarity, as well as visual beauty. These include Diamond, Ruby, Sapphire, Spinel, Alexandrite, Tourmaline, Emerald, Aquamarine, Garnet, and Tanzanite.

How is a gemstone valued?

Gemstones are valued in order of hardness, as this is a big factor with relation to durability & longevity when set into a piece of jewellery. This is followed by rarity, aesthetic beauty, and then market demand. Each gemstone variety will be more specifically valued by these governing qualities.

What is the rarest birth month gemstone?

Alexandrite is one of the rarest of all gemstones and was only discovered about 200 years ago in the Ural mountains of Russia. The June birthstone Alexandrite is a colour changing form of Chrysoberyl, with the most desirable colours being green, bluish green, olive green changing to red, violet/red, purple/violet in incandescent light.

What gemstones are best suited for an engagement ring?

As an engagement ring is worn every day, the only natural gemstones we’d recommend for their hardness & durability, in order are Diamond, Ruby, Sapphire, Spinel, Alexandrite, Garnet, and Tourmaline.

Are gemstones a good investment?

Like any rare & precious commodity, gemstones are always increasing in value. Pink diamonds from the Argyle mine increased value on average of 11.5% per annum from 2005 through to the mine’s closure a few years ago. Alexandrite, Sapphire, Ruby, and Tanzanite have all increased in value significantly over recent years too.
