Our first purchase at Gems of La Costa was at Christmas! The service Chad gave us was exceptional with a variety of beautiful sparkling rings to choose from.

The service and attention to detail is amazing! I worked with Samantha to re-design my wedding ring for my 25th wedding anniversary and I couldn't be happier with the result. They are skilled and wonderful to work with.

Very happy with the service we received? We had a ring that had been bent from a previous cleaning and mishandling of a jeweler. They assisted us quickly and with out a charge.

We will be returning!

Custom Design & Fabrication

Custom design jewelry usually starts with a good understanding of what you are looking for. Starting with a scan of your existing diamonds or gemstones, you want to integrate is the first step that allows us to create a mockup you. Sketches of designs or Photoshop mock-ups are a good start for us to find out what you are looking for and narrow down details and size considerations.

Computer Aided Jewelry Design

In recent years CAD, (Computer Aided Design) is being used to create more intricate designs than what was possible with traditional wax carving or making jewelry by hand.

After the initial consultation with one of our master jewelers, we will create a CAD design on the computer for your custom piece. One of the unique things about having a custom CAD design, is that you can view your jewelry (before we make it in metal)  from multiple directions and everything is proportional. Having everything in proportion is  sometimes lost in a hand drawing.

The computer simulation is a rendering of the CAD file that looks more like the real finished piece. This step enables you to see the piece from all sides and takes the guess work out of the custom designs. Furthermore, we can make adjustments to the design if needed. We will show all the views including side, top, end and a three dimensional view. This way you get to be part of the process to make sure you’ll be happy with your unique design.

Next, the CAD file “instructions” are sent to a 3D printer that is essentially a wax growing machine. It grows the design by building up layers of wax or resin that gives us the 3D model we use for the lost wax casting process. When the casting is finished, the gemstones/diamonds are set into the ring and the final finishing is completed.
