We can custom design and manufacture your perfect piece of diamond jewelry rapidly and accurately. It will be exactly what you want, with all of the quality features found only in the most exclusive custom designed jewelry.
We use state-of-the-art technology, originally developed for the computer and plastics industries, to bring 21st Century speed and precision to the process of design, prototyping, casting and finishing of precious diamond jewelry in gold, and platinum.
We take your design concept, such as some pictures and drawings and produce a CAD (computer aided design) graphic/picture of your design. We suggest elements and features based on our experience. We automatically include key quality items such as structural integrity features, a heaver and more comfortable shank on rings and strong diamond mounts that enable the maximum light performance (sparkle). You review the design and we make any changes you want.
Once we have your approval, we make a high-tech resin (similar to plastic) model. You get to see and wear the model. We can even sit the diamonds into the model. The model is an exact replica of what we will produce in precious metal for you. When you approve the resin, we make your custom design out of the metal your have selected, finish, polish and then set your diamonds.
If you would like, we can have your jewelry officially assayed, (analyzed for purity and certified/hallmarked) by the Company of Goldsmiths in Dublin Castle, Ireland. We can also have your Diamonds certification number laser inscribed on its gridle, so you can always identify your diamonds using a high powered magnifier/loupe.
You now have a “one of a kind”, very special heirloom, designed by you!
