Design Your Ring With Us

Engagement Rings Computer Design

Computer-Aided Design (CAD) – perfectly accurate

We use Computer-Aided Design (CAD) to produce every unique ring that we sell.  This software enables us to showcase any style you like to your finger size and using the actual gemstone measurements.  Clients can email us photos of their favourite design and we can add in engraving, filigree, side diamonds and any style adjustments to personalise the ring image.  We email this CAD file for client approval before manufacture. Contact us and start this amazing process.
