Step by Step Process


Have a custom design idea in mind?

Please either draw it or send us a picture of the setting, and we will be happy to design it for you. Below is a practical example of how this process works. You can email your idea to Here is a step by step guide into how this process works. 

Step 1 -

Submit your custom design idea or send us a picture of your desired setting: engagement ring. earrings, and/or pendents among others. While submitting your design idea, please also let us know if you want us to provide the center gemstone or not so that we can quote you accordingly. If you already have a gemstone, please let us know the size and dimension of it. Please also share the ring size information at this point. It would also be extremely helpful to have a sense of your budget at this point, especially for the center stone or diamond. 

Step 2 -

Based on the information you provide, we will share a quote for how much it would cost to make the custom setting. We will also provide multiple options. We work with all metals as well as different gemstones. We can also share ideas for using something as an alternative to diamond if you are on a budget or don't have taste for diamonds. 

Step 3 -

If we agree on the pricing, we will send you a PayPal Invoice or create a listing on for the agreed price with clear terms and conditions specified. You may also review our return policy at this point or ask any questions you might have. 

Step 4 -

Once the payment is cleared, we will draw a CAD rendering design for you within two business days to seek your approval. Please note that this is a very important stage prior to the production of the item. Please review the CAD design carefully and make any changes that you want at this point. Please also make sure that you provide us accurate details of the center stone in millimeter (if you are providing the main stone) as well as an accurate ring size. While resizing a ring is not an issue at a later stage, it is not a recommended option given that the side diamonds get disturbed and will need to be tighten again - a very labor intensive process. 

Step 5 -

Once you approve the CAD design, we will start the production process. This is when we make the actual jewelry. It could take anywhere between 8-10 days to finish the jewelry, and it would depend on the level of orders we receive. 

Step 6 -

Within 10 to 12 days, we will mail the finished custom setting or semi mount to you.

Custom Designs Gallery

Below is a gallery of the custom designs we have worked with our clients. Please check them out to see the quality of our custom work as well as to get ideas for a custom engagement ring or other custom jewelry in order make a truly unique design for yourself or a loved one. 

Mary's settings that prompted her to write the above email to us:

These were custom made mountings for two ring mountings and one custom made pendant for three tanzanites. Mary had large stones and was not sure if anyone would be able to make precise settings for them. After contacting us, she was surprised with our prices. She placed three orders for these custom settings with us and after seeing the result, she said she "was over the moon with the quality of our work." 


Custom Halo Engagement Ring Designs:

design 1- this was a challenging design to make as it had several elements of custom filgrees and milgrains. It toke a month of back and fourth to get this incredible design for an emerald cut diamond work... We are glad we were able to bring our client's vision into reality. These pictures really do not do justice to the delicate design that our goldsmith and designer produced. 


Design 2 - three unique custom halo engagement ring designs custom made after the CAD rederings were approved by client. One of the designs was made for a three carat round ideal cut VVS G color diamond. We are glade our client trusted us to make a strong platinum setting for a diamond of such value and brilliance:


Design 3 - Custom cathedral style engagement ring design with excellent cut diamonds - unique custom design after many alterations. The client wanted to integrate elements of different designs and was very specific about the size of the side diamonds as well as how they should be set. We were happy to receive a five star rating from and she continues to refer other customers to Petra Gems. 


Design 4 - custom cushion double halo ring and custom cushion halo pendent double halo setting semi mount with pink diamonds on the inner halo as request by client… Our client sent his expensiveopal and diamond in order to set in this setting. After completing the work, he couldn't believe how well done it was. Again, our master goldsmith and designer are the best when it comes to custom jewelry design. 


Design 5 - a master piece for a hooping three carat center diamond – exceptional platinum setting with VVS diamonds.  This one was handcrafted with best quality melees available in the market to match the center stone which was a 3ct VVS2 colorless and ideal cut round diamond. 


Design 6: custom Pear Cut Design setting for three exceptional quality GIA graded pear cut diamonds - center stone is 1.7 carat pear cut and side diamonds are 0.4 carat each. All colorless VS quality diamonds. 


Design 7 - custom halo rose gold engagement ring setting for an exceptional GIA graded 3.3 carat natural emerald gemstone. The client had a clear idea for how this should look and was thrilled with the outcome. We found this 3 carat deep green color emerald for a price four times less than what she was quoted. While we make a small profit, we always look out for the best interest of our clients. It is best to use our honest opinion and expertise instead of ending buying a gemstone or diamond at a much higher price. 


Custom 8 - Custom Oval Cut Diamond Engagement Ring in Rose Gold that we have also built in white gold and platinum. An exceptional design! This is one of our popular custom halo designs for an oval cut diamond. We can also modify it for any other shape diamond. It is also available in white gold or platinum. 


Design 9- a truly unique custom swirl engagement ring design with three rows of mixed cut diamonds. The center stone is a GIA graded deep brown color diamond as requested by the client. We work with thousands of diamond dealers and find any fancy color diamond for our clients and at next to wholesale price. If you in the market for a fancy color diamond, please contact us and we would be happy to provide you several certified options. 


Design 10 - unique swirl infinity design with two tone rose and white gold and the top of the engagement ring is halo as pictured. A unique contemporary design. This is one of our top selling custom design and we can change the metal type based on client's suggestions. 


Design 11- a true master piece – a split shank custom engagement ring with eagle prongs showcasing an incredible yellow diamond.  This is a true yellow cannery diamond that we set for our client. The pictures really don't do justice to the beauty of this engagement ring. 


Design 12 - custom double shank cushion halo engagement ring for an incredible round brilliant cut diamond. This two shank halo design is very elegant and can be modified for any shape stone. The six eagle prongs particularly adds to the beauty of this setting, but it can also be designed in four prongs as pictured. 


Design 13: unique classic round and oval cut diamond engagement rings custom made for clients that wanted a classic design with an exceptional round and oval cut diamond with maximum brilliance. These designs are ideal for large diamonds with fire and quality. 


The Custom Jewelry Making Process:

The step by step process begins with the initial consultation. The client wants to bring a custom engagement ring or jewelry idea to life. It is the job of the designer to aid the client in making the process easy and to bring the desired design into life. At Petra Gems, we try to take as much details as possible upfront in order to ensure that all the different elements are taken into considerations before we proceed to production work. 

So the process begins.

Step one – CAD:

After the design is agreed upon and diamond or other gemstone is selected, the designer makes a sketch of the design. In our case, we make a CAD rendering design through a CAD software (examples shown above). It will show the client a three dimension view of the proposed ring or jewelry. While it will not look exactly as the final jewelry (the final product is always prettier of course), it will do the job of sufficiently giving the client an idea of how jewelry will look as well as to provide an opportunity for the client to make any changes to the design.

Step two – Wax:

Once the CAD is approved, the designer or goldsmith makes the wax. The wax is used to create an exact replica of the jewelry in a flexible and cost effective manner. Since wax is cheap, we don’t have to worry about making the piece perfect in the first attempt – it might take 2-3 attempts to make the right wax model for the mold. Wax is a life saver as it helps remedy any potential structural issues and smooths the surface to avoid too much polishing at the end of the process.

Step three – Making the Mold:

The third step is to put the wax into a plaster-based investment mold material to melt out the wax and make a hallow version of the jewelry. This step involves several tasks, including appropriately securing the mold, properly mixing the investment material, removing any air bubble from the investment mold through a vacuum chamber, pouring the investment mold mixture into a flask and allowing it to set, placing  the flask 1300 digress in kiln set, and finally checking the mold for any obstruction and removing the mask.

Step four – Casting the Jewelry:

In this step, the metal of choice is melted and poured into the mold. Once the metal is cooled off, it is removed slowly with the help of cold water.

Step five: Finishing the Jewelry:

In this step, a grinder is used to cut away any unwanted metal from the jewelry. An acid bath is also used to remove any remaining plaster from the jewelry. Once done with the initial cleanup, a metal buffing tool and jewelry polishing tool is used to finish the jewelry. Also, it will be extra work to add any stones or make prongs for diamonds and other gemstones depending on the jewelry/ring design. For white gold, radium platting would also be needed. 

At Petra Gems, after finishing the jewelry, we often also send pictures to the client prior to shipment. We also provide a beautiful jewelry box with each custom design. If desired, we can also provide an appraisal for the jewelry that will show the description and value of the item as well as outlining what type of metal was used in the production process and the grading of the diamonds or other gemstones.

Rest assured, client satisfaction is our top priority. Be sure to reach out and ask questions before making a final decision. It is important to us that our client make an informed decision and are aware of all the different elements of the process prior to placing an order. We also try to provide as much information as possible on gemstones and diamonds so that your purchase is more of an investment than just an other luxury buy.
