Metals & Materials

Metals & Materials Sara Montgomery Designs

At Sara Montgomery Designs & Metalworking Studio, we offer a diverse range of high-quality materials to create unique and stunning jewellery pieces. Our selection includes various metals, gemstones, and natural and repurposed materials, ensuring that each piece is completely unique. 


We use a variety of metals in our jewellery to cater to different tastes and styles. Our selection includes:

- Sterling Silver: Known for its durability and bright finish. North American and many countries have a standard of 92.5% Fine Silver and up to 7.5% Copper. This can vary wildly by country and manufacture. Some can have the increasingly used and dangerous Nickel, so be careful of your supplier!

- Argentium Silver: A modern alloy that is highly tarnish-resistant. 

- Fine/Pure Silver: Composed of 99.9% pure silver, ideal for intricate details. Great for Silver Clay and fine details. 

- Copper: Valued for its rich, reddish-brown colour that develops a natural patina. 

- Brass: An alloy of copper and zinc with a warm, yellowish tone. Can look very much like gold depending on alloy. 

- Bronze: Made primarily of copper and tin, offering a distinctive, antique look. Used in base metal clay and sand-casting. 

- Gold: Available in various karats (24k, 22k, 18k, 14k, 12k, 10k, 9k) and many colours, including yellow, white, green, purple and rose gold. Along with the Japanese techinque of Keum-boo

- Gold-Filled: Offers the look and feel of gold at a more affordable price. This type will tarnish over time, and can with much wear, have the gold rubbed off. Gold Filled is best for items like earrings that do not come into contact with skin or clothing. 

- Aluminum: Lightweight and versatile, widely available. 

- Iron - Amazing properties - great for tools and additions to jewellery
