Studio Nonna Jewelry

Studio Nonna Jewelry: Inspired by Designs Worth Passing On

Studio Nonna is a jewelry brand inspired by original designs created over 40 years ago.

What once started as personal pieces, designed by my Nonna for herself, now forms the foundation of a modular jewelry concept that reimagines her original idea for today.

At Studio Nonna, jewelry is designed to be worn, combined and kept for years to come. Each piece reflects a balance between tradition and modernity — rooted in original ideas and reimagined for today.

The Idea Behind Modular Jewelry

Our signature hoop charms allow you to create your own combinations, making each piece personal and versatile. From natural stones to sculptural shapes, every design is created with intention and longevity in mind.

The Materials We Use At Studio Nonna

Studio Nonna jewelry is crafted for everyday wear — waterproof, non-tarnish and made to accompany you through all moments of life.

We work with carefully selected materials such as 316L stainless steel with a long-lasting PVD coating, 925 sterling silver, and 18k gold vermeil.

Studio Nonna Jewelry: Made to Stay With You

Each material is chosen for its durability, comfort on the skin, and its ability to maintain its appearance over time.

Rather than following short-lived trends, the focus lies on creating pieces that feel considered, versatile and personal — designed to move with you and evolve through the way you wear them.

More than just jewelry, Studio Nonna is a story carried forward — from one generation to the next.

Designed in Germany. Crafted to be worn, combined and passed on.

The Jewelry Materials We Use

At Studio Nonna, material quality is at the heart of everything we design. Our jewelry is made to last, feel good on the skin, and fit seamlessly into everyday life.

Below you’ll find a transparent guide to all materials used across our collections.

316L Stainless Steel Jewelry

What is 316L stainless steel?

316L stainless steel is a premium-grade material commonly used in medical applications due to its durability and skin compatibility. It is widely recognized as one of the most durable materials in contemporary jewelry.

Why we use 316L stainless steel

Our stainless steel jewelry is:

  • Hypoallergenic and nickel-free
  • Waterproof and rust-resistant
  • Highly durable and color-stable

This makes it ideal for everyday wear and long-lasting jewelry pieces.

Is stainless steel jewelry waterproof?

Yes. Our 316L stainless steel jewelry is waterproof and designed for daily use. For maximum longevity, we recommend avoiding prolonged exposure to harsh chemicals.

Gold Vermeil & Hoop Charms

What is gold vermeil?

Gold vermeil is a high-quality plating technique that combines a solid 925 sterling silver base with a thick gold layer.

Our gold vermeil specification

  • Base: 925 sterling silver
  • Gold layer: 2.5 micron
  • Significantly more durable than standard gold plating

A 2.5 micron gold layer ensures a rich gold tone and increased longevity.

Gemstone Hoop Charms

For our chunky hoop charms, we exclusively use real, natural gemstones. Each stone is carefully selected for its individual character, making every charm slightly unique and adding an elevated, more refined feel to each piece.

Our chunky hoop charms are designed to be modular and interchangeable. They can be styled with different hoops, allowing you to create versatile looks with a single piece.


Navajo Turquoise Jewelry - 925 Sterling Silver

What is Navajo turquoise jewelry?

Navajo turquoise jewelry is deeply rooted in traditional Native American silversmithing, where turquoise holds both cultural and symbolic significance. The combination of handcrafted sterling silver and natural turquoise stones has been passed down through generations and is known for its distinctive, timeless character.

Each piece reflects the individuality of the stone and the craftsmanship behind it, making Navajo turquoise jewelry both meaningful and one of a kind.

What is 925 sterling silver?

925 sterling silver consists of 92.5% pure silver and is a classic precious metal used in fine jewelry.

The origin of our Navajo turquoise jewelry

For our Navajo Turquoise Collection, we work in close collaboration with experienced silversmiths based in New Mexico. We personally know the artisans behind these pieces and value the traditional craftsmanship that goes into each design.

This close partnership allows us to ensure high material quality, authenticity, and a respectful approach to the cultural origins of the jewelry.

Why sterling silver for this collection

Our Navajo Turquoise Collection features:

  • Genuine 925 sterling silver
  • Natural turquoise stones
  • One-of-a-kind pieces with unique character

Does sterling silver tarnish?

Yes. Sterling silver may oxidize over time due to air exposure. This is a natural process and can easily be reversed with gentle polishing or regular wear.

Jewelry Materials – FAQ

Is your jewelry suitable for sensitive skin?

Yes. All materials used are carefully selected and suitable for sensitive skin.

Which pieces are waterproof?

Our stainless steel jewelry is fully waterproof and designed for everyday wear, including water exposure.

Gold vermeil and sterling silver pieces can also be worn in water without being damaged. However, frequent or prolonged contact with water — especially saltwater or chemicals — may affect the surface over time. To preserve their finish and shine, we recommend gentle care.

Is gold vermeil real gold?

Yes. Gold vermeil features a thick layer of real gold applied to a sterling silver base.
