Custom Design & Recent NJJ Creations

Neville recently manufactured this amazing diamond and ruby half sovereign set ring  for a customer.
These images show the progress from CAD design  through to the finished ring.
Our customer was thrilled with the result.







We are a New Zealand owned and operated company (since 1987) and offer a full design, manufacture and after sale guarantee service all in one location. Let Neville use his expertise to help you select your own certified loose diamond.


At your initial meeting with us we will discuss your specific design requirements and budget. We are very conscious that you are trusting us with what is usually a major purchase to mark a milestone in your life.

We then create a computer image of the ring design for you to see before the ring is manufactured as we believe this gives our clients confidence in the final result.

We are able to source diamonds and precious gems direct from the wholesaler and with over 30 years of experience we can always create a design unique to your needs and which you will enjoy wearing forever.
