My name is Louis Benowitz G.G., 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 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.  In addition I have successfully owned and managed fine jewelry stores.

For digital hardware we have two SolidScape 3-D RP (rapid prototyping) wax modeling machines, two fast CPU’s, digital scanner, high megapixel digital camera, all format memory card readers and more.


For jewelry hardware we have a full on-site gemological laboratory.  We also work directly with a manufacturing facility featuring a complete casting room, 7 complete jewelry benches, complete finishing room and more.  We can take your sketch, picture or idea to a virtual 3-D design and output the design into a castable wax model.  We can then oversee the complete process of casting the master model, pre-finishing, mold making, quantity casing, finishing, gemstone

supply and finished product delivery.

We take your logo, ideas, drawings or pictures and create finished jewelry designs to your specs.  We use Rhinoceros CAD software which is the best nurbs modeling program on the market.  Click here to learn about Rhino  Combine that powerful software with Matrix and we can make any design a 3-D reality.  We can keep your jewelry designs and ideas secure, never releasing them to anyone but you for any reason.  We can supply all gemstones including diamonds, all varieties of natural colored stones and all different types of metals at the right price.  Or we can take your STL files from Rhino or other cad software ( click here to email ) keep them secure and grow wax models.  NOTE:  Because we have two state of the art rapid prototyping machines (unlike milling machines) we CAN grow your models with undercuts, fine details and hollow areas.

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.  Once received we will telephone/email you to discuss and confirm your order.  Or you can see for our main quote page.  The CAD department then goes to work and creates your piece in stunning 3-D detail.  We are ready to render the piece based on the choices you desire.  A platinum and diamond ring on snow or a platinum and rose gold pendant with tsavorites and pink diamonds on burl wood, either way your customer or board members will be amazed and delighted.

After the image is approved we then “grow” the wax jewelery model on one of our two in-house rapid prototyping 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.  For those of you who want to send us your STL files we can suggest the best STL settings.  Everything is down in house.  This way you file is secure, we will either save your file in a password protected area, write you a disk and delete or completely delete.  The finished model, if desired, can then be inspected.  Any design or size changes can be done rapidly saving time and money.

The model is then ready for the casting process.  We use precise digitally controlled electric burnout ovens.  We have co-developed a special burnout cycle to constantly 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 or two tones the goldsmith or platinumsmiths will assemble and prepare the piece for the setter.  If you supplied your own stones we will have them set them in the correct manner.  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!
