Where are the pieces produced?

All of our BOLTENSTERN pieces are manufactured and finished in our Viennese workshop, founded  in 1964. The 3D printing is carried out in Vienna and by our trusted European partners. We work  together with the most renowned international partners, ensuring we remain at the forefront of  innovation. Our in-house skilled craftsmen are world-renowned for their knowledge and  professionalism, and some have been with us for more than forty years.

How are the pieces produced?

Our 3D printed pieces are initially created by coding an algorithm based on complex mathematical  calculations. Once they have been 3D printed, they are finished and polished to perfection by our  in-house goldsmiths. You can read more about the technology used to create our pieces here.

Do you do custom designs, and how do I go about ordering a custom piece?

Yes, we most certainly do. With our state-of-the-art technology and years of goldsmithing experience,  we can make pretty much every wish you might have come true. Contact us at hello@boltenstern.com,  and we will guide you through the process of designing your very own custom piece of  BOLTENSTERN jewelry.

If the pieces are 3D printed, why are production times 2–4 weeks? 

When it comes to 3D printed fine jewelry, the process of production is complex. Designing the jewelry  pieces and creating algorithms can take months or years of development. Moreover, although the  printer creates the unique structures, the surfaces remain rough. Our goldsmiths polish and finish  every piece of fine jewelry by hand, which takes time. You can read more about how our fine jewelry  pieces are produced here.

Yes, you can trust BOLTENSTERN.com. We use industry-standard encryption technologies when  transferring and receiving customer data that is exchanged with our site server.

How can I best take care of my BOLTENSTERN fine jewelry? 

BOLTENSTERN maintains the highest standards in design, materials, and craftsmanship, creating  jewelry that can be passed down from generation to generation. With some simple, basic care, you can  help preserve and protect your jewelry for years to come. Daily wear, dust, and pollution can all  conspire to cloud the brilliance of gemstones, and the surface of gold, platinum, and silver can become  dulled.

Professional cleaning and polishing is recommended as often as once a year. Which is why we  encourage you to bring your BOLTENSTERN jewelry back to us for professional servicing. Our  showroom staff are knowledgeable and experienced in all aspects of jewelry care.
