Naturalcure: Your Specialist Manufacturer for High-Purity Noble Metal Colloids

At Naturalcure, uncompromising physical and laboratory-grade purity comes first. As a specialized manufacturer, we freshly produce colloidal silver (silver water) and colloidal gold in precisely calibrated concentration levels – ranging from classic 50 ppm to 100 ppm and 200 ppm, all the way up to our exclusive 1000 ppm high-concentration dispersion.

Why Colloids from Naturalcure Make the Decisive Quality Difference

• Certified 99.99% Noble Metal Purity: For both our colloidal silver and colloidal gold, we exclusively use certified electrodes with a purity grade of at least 99.99% (Four Nines Fine / 24 Karat).
• Advanced High-Voltage & Electrolysis Process: While standard products often rely on chemical reducing agents, we produce our colloidal gold using an elaborate physical high-voltage plasma process and our silver water through precisely controlled electrolysis.
• Ultrapure Type 1 Water (Aqua bidestillata): We exclusively use double-distilled and deionized laboratory water with a minimal residual conductivity (< 0.1 µS/cm) as the dispersion medium. This guarantees a stable electrostatic charge potential (zeta potential) and ultra-fine nanoparticles (1 to 20 nm).
• 100% Free from Additives: Our dispersions consist exclusively of ultrapure water and pure noble metal particles – guaranteed free from salts, chlorides, proteins, citrates, or artificial stabilizers.
• Protected in Pharmaceutical Amber Glass: Immediately after production, every batch is bottled in UV-protective pharmaceutical amber glass bottles to reliably shield the delicate electrical charge of the colloids from light exposure.

Our Core Products: Colloidal Gold & Silver by Concentration

To ensure you receive the exact particle density required for any technical, analytical, or laboratory application, we offer our freshly produced noble metal dispersions in clearly defined concentration levels:

Colloidal Gold (50 ppm, 200 ppm & 1000 ppm)

True colloidal gold (gold sol) is characterized by its distinctive pink to ruby-red color caused by surface plasmon resonance and is atomized directly from 99.99% fine gold using the high-voltage arc process:

• Colloidal Gold 50 ppm (500 ml): The optimal balance of ultra-fine particle distribution and maximum long-term stability in a generous 500 ml amber glass bottle.
• Colloidal Gold 200 ppm: Four times the particle density of 50 ppm, featuring an intense ruby-red hue and high zeta potential.
• Colloidal Gold 1000 ppm (High Concentrate): Our highest concentration level containing exactly 1,000 milligrams (1 gram) of pure fine gold per liter of ultrapure water – manufactured under the strictest laboratory conditions.

Colloidal Silver / Silver Water (50 ppm & 100 ppm)

High-purity silver sol made from 99.99% fine silver and Aqua bidestillata, featuring a pronounced Tyndall effect and high suspension stability:

• Colloidal Silver 50 ppm (500 ml): Our proven classic in the 500 ml supply bottle with 50 mg of fine silver per liter of water.
• Colloidal Silver 100 ppm (500 ml): Highly concentrated silver water with double the colloid density for demanding laboratory and processing applications.

Physical Authenticity Features: How to Recognize High-Quality Colloids

Whether a liquid is a genuine, physically produced noble metal colloid or merely a simple salt solution can be verified using clear physical criteria:

• Visible Tyndall Effect in Laser Light: When a focused light or laser beam is directed through the glass, the light scatters off the freely suspended gold and silver nanoparticles. A fine, continuous cone of scattered light becomes visible in the liquid (Tyndall effect), whereas a simple salt solution shows no light cone.
• Natural Coloration via Surface Plasmon Resonance: Genuine colloidal gold is never metallic yellow; due to the quantum optics of the nanoparticles, it shimmers in a characteristic pink to deep ruby-red. Highly concentrated colloidal silver (from 50 to 100 ppm) displays a clear to gentle golden-yellowish tint due to the same physical light refraction effect.
• Stable Zeta Potential Without Sedimentation: Because we produce every batch fresh at Naturalcure, the nanoparticles possess a maximum uniform surface charge. They repel each other, remain permanently suspended in the water through Brownian motion, and form no dark sediment at the bottom.

Important Legal Notice Regarding Product Classification

Colloidal silver and colloidal gold are manufactured and supplied by Naturalcure exclusively as technical and laboratory-grade raw materials for scientific, analytical, and further processing purposes. In accordance with applicable European Union regulations – in particular the Novel Food Regulation (EU) 2015/2283 – colloidal silver and colloidal gold are not approved as food or dietary supplements. They are expressly not sold for human consumption or for medical or therapeutic purposes.
