Design with us in person or remotely

Custom jewelry design is not cookie-cutter or mass-produced. A bespoke item is inspired by your personal story and expertly crafted to reflect it with beauty. When you collaborate with Herz, you will be working with your very own designer to create a one-of-a-kind piece.

Herz designs custom jewelry for clients around the world. But we aren’t just jewelers. We are expert gemologists who have studied diamonds and other gemstones extensively. We are seasons designers with a keen creative eye. 

Together, we look forward to bringing your ideas to life.

Fine jewelry and bespoke bridal

Whether you want to design an engagement ring, solitaire, wedding band, or some other personalized piece, we look forward to becoming your private jeweler. You can buy with confidence at Herz, knowing our diamonds and precious metals are ethically sourced. 

As professional gemologists, we build beautiful custom jewelry from a unique perspective, choosing from various stunning diamonds and gemstones. Our process is simple and accessible to help you obtain a high-quality diamond that fits your budget.

Step 1: Discovery

If you can imagine it, Hertz can design it. Tell us what you envision so we can transform your story, ideas and preferences into a productive personal design experience.

Step 2: Stone Selection

Choose and personalize the diamond or gemstone of your choice. Considerations include size, carat weight, cut, style, color and more. This step is where the design takes shape with careful attention to your individual style and preferences.

Step 3: Final Design 

We will propose several prototypes before refining the final design. Depending on the unique  characteristics of your piece, we will provide a quotation and estimated manufacturing time. 

Step 4: Creation

Expert goldsmiths execute our manufacturing process. It includes the following steps: 3D design and modeling, 3D printing, casting the jewel in precious metal, refinishing, polishing, and setting the diamond or gemstone. We offer engraving upon request.

Step 5: The Reveal

The moment everyone has been waiting for–a dream becomes a reality, and a story is brought to life. If you are nearby, you can visit our store to see your new work of art and try it on. Or, we can send your order directly to your residence through insured transport. Either way, the creative journey is complete, and your one-of-a-kind design is yours to cherish forever.

Traditional European design with a modern touch

Our jewelry is heavily influenced by traditional European design, with reverence for ancient Andalusian jewelry-making methods. Our skilled team has studied the cultural influence of jewelry and the traditional methods from which all modern techniques evolved. We believe our dedication to understanding history will help us make our own one day!

If you want personalized designs that blend modern technology with traditional inspiration, you’ve come to the right place. Our family-owned shop is proud to serve our local community and our global clientele. 


Each bespoke jewelry piece is unique, and budgets can vary widely. Pricing depends on the design and materials used to create your item. Our experts will work with you to create a design that fits your budget and realizes your vision.


The timeline for your piece will depend on the complexity of your project and Herz’s workload at the time of commission. Once we discuss what you have in mind, we can determine how long it will take to complete your jewelry.

You don’t have to be local to collaborate with us! Herz works with customers all across the globe to bring their designs to life. We are accustomed to working with customers remotely, whether by email, phone or video call.
