The Story Behind Our Materials: Reclaimed Gold & Silver at Astartelux Jewelry

At Astartelux, our commitment to sustainability begins with the materials we choose. Each piece of jewelry we create is crafted from responsibly sourced, recycled gold and silver—giving new life to materials without compromising on beauty, quality, or ethics. This sustainable approach ensures that our jewelry isn't created at the cost of the planet or the people who inhabit it.

Why We Choose Reclaimed Gold & Silver

We love that gold and silver can be endlessly recycled. What was once a treasured heirloom can be transformed, melted down, and reimagined into a new design, carrying a renewed significance for a new wearer. This circular approach reduces waste, conserves resources, and honors the emotional legacy embedded in every piece.

A Deep Dive into Our Precious Materials

Gold: A Timeless Foundation

Gold is the most revered and enduring metal in fine jewelry. It doesn't tarnish, rust, or corrode, and its versatility allows for a wide range of hues and expressions.

Yellow Gold

Warm and elegant, yellow gold is the most traditional and timeless form. The shade of yellow depends on the alloy mix and purity:

18K (750) = 75% pure gold — a richer hue with ideal strength for fine jewelry
14K (585) = 58.5% pure gold — durable and slightly paler
Lighter yellow indicates more silver in the alloy; deeper tones indicate more copper

Care Tips: Yellow gold is easy to maintain, resize, and repair. Clean with mild soap and water, and store separately to avoid scratches.

White Gold

Created by alloying yellow gold with white metals such as silver and palladium. At Astartelux, we strictly avoid nickel to comply with EU Nickel Safety Regulations. Our white gold is often coated in rhodium to achieve a bright, platinum-like finish.

Care Tips: Rhodium plating may fade over time and can be easily re-plated. Clean gently and replate as needed to maintain its luster.

Rose/Red Gold

An alloy of gold and copper that creates a romantic pink hue. The more copper used, the deeper the color. Rose gold is ideal for vintage-inspired and mixed-metal designs.

Care Tips: Rose gold is strong thanks to copper but still needs regular cleaning to prevent buildup. Avoid harsh chemicals and polish gently with a soft cloth.

Understanding Gold Purity (Karat Ratings)

Karat	Purity	Fineness Stamp	Notes
24K	99.9%	999	Too soft for jewelry

18K	75.0%	750	Ideal for fine jewelry
14K	58.3%	585/583	Durable and budget-friendly

Sterling Silver: Elegant and Eco-Friendly

Sterling silver is made of 92.5% pure silver and 7.5% copper, making it stronger and more suitable for everyday wear. High-quality silver jewelry carries the “925” stamp, a mark of its authenticity.

Care Tips:

Store in anti-tarnish cloth pouches or separate compartments
Avoid humidity, perfumes, chlorine, and cosmetics
Clean regularly with silver polish or a soft cloth to remove tarnish
