custom design

Custom Designs

Experience the joy of designing your own ring or jewelry. Work alongside a professional jewelry designer and create a truly special, distinctive piece that reflects your own individual style. Our on-site certified gemologist and master jeweler regularly design and build custom pieces for rare precious gemstones.

We can take your own personal sketch, photograph, or idea and make you that one of a kind piece you always dreamed of.

Our artists will sketch some concepts, and then produce a computerized rendering of your design, allowing you to view it in 3-D, from every angle, and visualize what the finished piece will look like. Upon your approval of the rendering, our jeweler creates a wax model, allowing you to actually touch, hold, and try it on.

Many of our designs have meticulously hand fabricated filigree designs, beautiful hand engraved patterns, and hand set stones, which insures you are getting top notch craftsmanship.
