For centuries, silver has been valued for its purity, versatility, and protective qualities. From ancient civilisations storing water in silver vessels to modern applications in technology and personal care, silver continues to hold a special place in the world of natural wellness and everyday living.
At Nature’s Greatest Secret, we’re proud to continue that tradition with our range of premium Colloidal Silver solutions — including travel-friendly sprays, precision droppers, and eco-refill bottles in both 10ppm and 20ppm strengths.

What Is Colloidal Silver?
Colloidal Silver is a suspension of fine silver particles in pure water, created by applying an electrical charge to silver electrodes. These ultra-fine particles (ranging from 1 to 100 nanometres) remain evenly distributed throughout the water, resulting in a stable, high-purity solution.
In our collection, you’ll find two main types of silver:
- True Amber Colloidal Silver: Contains suspended silver particles, giving it its rich amber hue. With over 80% pure silver content, it represents the highest quality and purity, ideal for those seeking an authentic, premium formulation.
- Ionic Silver: Made of dissolved silver ions. While both types have long histories of use, colloidal silver is typically favoured for applications where particle-based silver is preferred.
Understanding PPM: 10ppm vs 20ppm
You’ll often see Colloidal Silver described by its concentration in parts per million (ppm) — this simply refers to the number of silver particles per million parts of water.
- 10ppm: A lighter, general-use concentration ideal for regular use and everyday routines.
- 20ppm: A higher concentration suitable for those who prefer a more concentrated formula.
Both options offer the same purity and stability — it’s simply a matter of personal preference and use.
A Brief History of Silver’s Use
Silver has been valued since ancient times. The Greeks, Romans, and Egyptians stored food and water in silver containers to keep them fresh. In the early 20th century, before modern preservatives and synthetic agents were widely available, silver was also used in a variety of household and cleansing applications.
Today, Colloidal Silver continues to be appreciated as a versatile and naturally inspired solution, with many people choosing it as part of a clean-living lifestyle.
