We only source metals which are held accountable to stricter environmental best-practices. and/or certified member of RJC (Responsible Jewelry Council), and/or LBMA (London Bullion Market Association)  to ensure minimal impact to local communities.

All companies within the membership of RJC and LBMA must have activities that are closely related to the London market gold bullion. These activities include trading, broking, shipping and storage, mining and refining, inspection and assaying and research.  LBMA’s Responsible Sourcing program for precious metals protects the integrity of the global supply chain for the wholesale precious metals markets.  Vital to the credibility of the standards is the broad scope, which includes measures to combat money laundering, terrorist financing and human rights abuses globally.

We offers cadmium free soldering and plating jewelry collection.

Cadmium is a dangerous heavy metal and a known carcinogen. The Agency for Toxic Substances and Disease Registry (ATSDR) lists cadmium as the number 7 most significant threat to human health, based on its frequency, toxicity, and potential for human exposure. Cadmium has a half life in the body around 10-30 years, meaning that a single exposure event can stick around for nearly a lifetime. 

Copper It can kill or inactivate many bacteria, viruses, and fungi on contact, a property called “contact killing” or oligodynamic effect. This works because copper ions (Cu⁺ and Cu²⁺) can:

• Disrupt cell membranes – damaging the protective outer layers of microbes.

• Generate reactive oxygen species – causing oxidative stress inside the cells.

• Interfere with proteins and DNA – stopping normal cell functions and replication.

That’s why copper and copper alloys (like brass and bronze) have been used for centuries in drinking vessels, door handles, coins, and medical equipment to reduce disease spread. Modern hospitals even use copper surfaces to help control infections.

In the jewelry industry, copper is rarely used in its pure form. It’s usually alloyed with gold, silver, or other metals (e.g., in rose gold, sterling silver, or brass) to change color, hardness, and durability. The antibacterial effect still exists

Copper in jewelry alloys can have an antibacterial property, but it’s weaker than pure copper and might be almost inactive if the copper is both low in percentage and sealed under a plating.

Here’s a reference table for common jewelry alloys and their likely antibacterial strength compared to pure copper:

Alloy / Material	Typical Copper Content	Surface Exposure	Relative Antibacterial Strength
Pure Copper (99.9%)	~100%	Bare surface	★★★★★ (very high – kills many bacteria within minutes to hours)
Brass (Cu + Zn)	60–90%	Bare surface	★★★★☆ (high – slower than pure copper)
Bronze (Cu + Sn)	80–90%	Bare surface	★★★★☆ (high – similar to brass)
Sterling Silver (92.5% Ag + 7.5% Cu)	~7.5%	Bare surface	★★☆☆☆ (low – copper effect minor; silver has separate antibacterial properties)
18K Rose Gold (75% Au + 20–22% Cu + small Ag)	~20–22%	Bare surface	★★☆☆☆ (low–moderate; copper effect present but weak)
14K Rose Gold (58.5% Au + ~33% Cu + silver)	~33%	Bare surface	★★★☆☆ (moderate; higher copper than 18K)
Gold-filled / Gold-plated brass	Core ~85–90% Cu (brass)	Usually plated with gold	Varies – low to none until plating wears off
Rhodium-plated alloys	Varies	Coating blocks copper	☆☆☆☆☆ (none – until coating is damaged)

Key Notes

• Percentage matters – higher copper = stronger antibacterial effect.

• Exposure matters even more – any plating, lacquer, or resin seals off copper, preventing ion release.

• Wear & tear can help – small scratches or worn spots can re-expose copper-rich surfaces over time.

Here’s your copper content vs. antibacterial strength chart for common jewelry alloys.

You can see that higher copper content (and exposed surfaces) gives stronger antibacterial effects, while coatings or low copper levels reduce it significantly.
