CommonSensus™ is more than a methodology — it’s a mindset. It challenges the blind consensus we accept simply because “it’s always been that way.” Instead, it replaces confusion with clarity, tradition-for-tradition’s-sake with fairness, and inconsistency with evidence.
Modern life is full of contradictions we tolerate without question:
We shrug, we laugh it off, but deep down we know it’s nonsense. CommonSensus™ asks: Why cling to outdated, inconsistent systems when universal clarity is possible?
The Karat Purity Scale™ (KPS™) is a universal system that measures the purity of all metals – not just gold – on a simple 0–24 scale. It is built on the familiar 24-karat gold system, where 24 karats equals pure gold, but expands it to include silver, copper, platinum, palladium, and beyond. For the first time in history, every metal can be expressed on the same universal scale of purity.
Notes on rounding & stamps
Millesimal fineness (‰) is shown to common hallmark values (e.g., 585 for 14k, 916 for 22k). Some regions use historical alternates (e.g., 583, 917). % purity mirrors the fineness value (‰ ÷ 10).
KPS™ = (purity % × 24) / 100 = karat for gold; tolerances shown in KPS points.
This patchwork of systems creates barriers: it confuses buyers, erodes trust, and complicates trade.
The trade in precious metals lacks unity and clarity
The world of precious metals is fragmented and confusing.
Every KPS™ grade is supported by strict tolerance levels:
That means whether you’re buying a wedding ring, a bullion bar, or an investment ingot, purity claims are consistent, measurable, and trusted worldwide.
With KPS™ precision isn’t optional – it’s essential. The Karat Purity Scale™ (KPS™) is only as strong as the science that underpins it. In the 21st century XRF technology (X-ray Fluorescence) is being relied on more and more to confirm and guarantee the exact composition of every metal.
XRF ensures that every valuation, every certificate, and every purity grade is based on evidence, not guesswork – the basis of KPS™ philosophy.
Traditionally, jewellers relied on visual checks, hallmarks, or crude acid testing to assess purity. These methods are often unreliable:
For the bullion marketplace, where value depends on purity to the decimal point, these old systems aren’t enough.
XRF analysis solves this problem. It gives laboratory-quality results in seconds, ensuring valuations that are fair, accurate, and transparent.
XRF machines work by firing a controlled X-ray beam at a sample. The atoms inside the metal respond by emitting fluorescent X-rays unique to each element. The machine instantly detects these signatures and calculates:
In seconds, we know whether a ring is 18k gold, 22k sterling silver, or 24k copper and we can price it with confidence.
The process can be summarised in four steps:
This technology, first pioneered in 1913, has been refined to deliver lab-grade analysis instantly.
Yes. The radiation exposure from a desktop XRF test is no greater than a dental X-ray. Used correctly, it poses no danger and does not make any object “radioactive.” Unlike acid testing, XRF is non-destructive.
XRF makes KPS™ possible. It bridges the gap between tradition and modern science, ensuring that purity – whether gold, silver, platinum, or copper – is measured with absolute confidence.
From the ancient carob seed to the first copper complaint, the story of bullion has always been about trust. Today, KPS™ ensures that trust — across all metals, all markets, and all people. One Scale. All Metals. Total Clarity.
