 Turning Green Diamond Ring

How it Works




During a free consultation we discuss your design idea, budget, and timeline to see if we're a good fit.




We hone in on the design of your jewelry through a round of artist renderings, wax models or both.




We work with our trusted vendors to present you a selection of diamonds or gemstones that suit your design and budget. You choose your favorite.




Your project takes shape! We create your finished piece using the design you've approved and the materials you've selected.




Your jewelry is complete and ready to present. We ship the finished piece to you, or you can pick up from my San Francisco Studio.

How Long Does It Take to Create a Custom Design?


In most cases, the full custom design process takes between 4 and 8 weeks.  The design discovery phase, which includes your consultation, design, and gemstone sourcing, typically takes the first 2 -3 weeks of that window. The creation phase of your item will take an additional 2 to 5 weeks depending on the complexity of your design and the lead times in our studio.


How much does a Custom Design Cost?


Custom designs begin at $1500. The finished piece of your design will depend on the materials you select, the complexity of your design, and the current metal markets. 


What are my Metal Choices?


I happily create custom designs in the precious metals listed below. For more info on these choices, read my precious metals comparison. 

    • 14k yellow gold
    • 14k rose gold
    • 14k white gold
    • 14k palladium white gold
    • 18k yellow gold
    • 18k rose gold
    • 18k white gold
    • 18k palladium white gold
    • platinum
    • palladium

    Due to the large time investment for custom pieces, I do not create custom work in sterling silver.


    Can You Work With My Gemstones?


    I only work with customer stones that are diamond, sapphire, ruby or other similar gemstones ranking an 8 or higher on the MOHS hardness scale. We will inspect your gems together [for quality, scratches, cracks, etc.] to determine if they are a good candidate for use in a new design.


    Can You Work with My Gold? 


    My commitment to sustainability means I like to recycle and reuse wherever I can. Customers can provide their old precious metal jewelry to recycle for credit towards their custom design project. The value will vary based on the jewelry you provide and the current metals market. 

    In some cases, I may be able to use the exact gold you provide in the new design. Currently this process is only offered for yellow and rose gold jewelry (white gold often becomes too brittle upon recasting.) The jewelry you provide must be of the same color and karat as the finished piece we are creating. A minimum amount of metal is required for the casting process to work. 


    While You're At It, Can You Repair My Jewelry? 


    I'm a small studio that is only equipped to handle repairs on the jewelry I create. If you need a jeweler who performs repairs I am happy to offer a recommendation. Please do not bring items for repair to your custom design consultation.
