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.

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.

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.
