Customer Stories

★★★★★

We met Khay at the annual wedding expo and she understood what we wanted as no other jeweler had before. We decided that Khay was the one for us.
We went for a consultation and Khay helped us decide on our rings to be designed. We had emails with diagrams to confirm what we wanted and then our special rings were made for us. We love our rings and it was a great joy to collect them as they were perfect.
Our rings turned out far better than we ever thought possible.

★★★★★

Having a more unconventional idea made me wary of choosing the wrong jeweller, but after being walked through the process by Khay, I knew that they would be very well suited to do my ring.
They handled the project well, with great communication, professionalism and creative energy.
We were able to iterate and discuss concepts easily, and found a great balance between the inspiration of the concept, and the practicalities of jewellery design

Miles W.

★★★★★

Going from jeweller to to jeweller looking for an engagement ring, we were so happy to find Khay. She listened to what we were looking for and offered knowledgeable feedback and ideas.
Khay designed a perfect ring and we were able to see a 3D render that looked more like a photo than a drawing.
The ring turned out great and now we are getting our wedding bands designed and made by Khay.

Parti Sapphire: The Complete Guide to these Multi-Colored Gems

Are multi-colored sapphires just poorly formed rejects that lapidaries couldn’t heat-treat into a uniform, marketable blue? Not by a long shot. They are highly sought-after geological anomalies, and treating them like a rinky dink renfaire trinket is a mindset as outdated as dial-up internet.
