LB JEWELRY DESIGN, CAD jewelry design





My name is Louis Benowitz G.G., I execute CAD jewelry design, am the founder of LB Jewelry Design, Inc and have been in the jewelry business since 1980.  In September of 1983 I graduated from the Gemological Institute of America then located in Santa Monica, CA… #1.  I studied CAD jewelry design in 2004.  Starting with CAD jewelry design we deliver high quality renderings before any physical work begins.  Then we work directly with manufacturing partners featuring a high tech casting facility, 7 individual jewelers who focus on different aspects of custom jewelry production and several different platers and polishers to deliver high quality finished pieces.  We can take your jewelry design sketch, picture or custom jewelry idea to a virtual 3-D design and output the design into a castable wax model.

We will also oversee the complete process of casting the master model, pre-finishing, mold making, quantity casing, finishing, gemstone supply and finished product delivery.  Since I am semi retired only accepting fine jobs or quantity orders.  I have traveled the world and consistently bring fantastic gemstones and diamonds to the market at the best prices.  Sapphire, Alexandrite and Spinel from Sri Lanka, Ruby and Tourmaline from Madagascar and Thailand. While Tanzanite, Tsavorite and Chromium Tourmaline come from Arusha and Mombasa.  Of course diamonds from Antwerp.  I have successfully owned and managed fine jewelry stores, now semi-retired focus on fine jewelry design.

There are several methods available.  The easiest is via email.  Simply email your jewelry design idea, logo and measurements ( click here to email ) to us.  If you are unsure, no problem, please send me an email including your sketch or picture and description arrives, we will agree on the details.  When the CAD work is finished renderings will be sent for your approval.  Whether your job is your own unique design, a fine platinum and diamond halo ring or a platinum and rose gold pendant with tsavorites and pink diamonds, your customer or board members will be amazed and delighted.

After the image is approved we then arrange to “grow” the wax jewelery model on a hi resolution solid wax modeling machine.  Unlike other processes like milling machines we are able to grow models that have undercuts, thin wires, beads and even hollow areas.  All this is done with the industries best detail and in solid wax for the best casting results.  The wax will be shipped to you for final inspection if needed.

After approval the wax model is then ready for the casting process.  We use precise digitally controlled electric burnout ovens.  No special burnout cycle is needed, our hi-res waxes provide porosity free, crisp and clean castings.  Using a magnetic barrel tumbler will pre-finish your casting.  If your jewelry design calls for multiple pieces our goldsmith will assemble and prepare the piece for the setter.  If you ordered stones from us we set those in the correct manner.  The jewelry is now ready for the finisher, probably the most important person in the shop.  He alone has the final important job of making it shine before you see it!
