Fischer GOLDSCOPE SD 510

Gold testing you can see

We verify gold with professional X-ray fluorescence (XRF), the same technology used by refiners and assay labs. No scratches, no acid, and the result in seconds.

How XRF works

What happens inside the analyzer

The Fischer GOLDSCOPE SD 510 is a professional XRF instrument made by Helmut Fischer for precious-metal analysis. It measures the composition of a piece directly, so the karat on the tag is the karat you get, and what you sell is valued for what it really is.

Place the piece

Your jewelry or coin goes into the analyzer's measuring chamber. Nothing is cut, scratched or filed.

X-ray fluorescence

A low-energy X-ray beam excites the metal atoms, and the detector reads the signal each metal sends back.

See the result

Within seconds you see the composition: gold content and karat, plus the other alloy metals.

Karat guide

What the numbers mean

Gold purity is measured in karats out of 24. The hallmark stamped on a piece shows its gold content in parts per thousand.

Karat	Gold content	Hallmark	What it is like
24K	99.9%	999	Pure gold. Very soft, so it is used mainly for bullion bars rather than jewelry.
22K	91.6%	916	The traditional Turkish standard. Rich yellow color and high gold value, used for chains, bracelets and Cumhuriyet coins.
21K	87.5%	875	Popular across Turkey and the Middle East. Slightly harder than 22K, with a warm yellow tone.
18K	75.0%	750	Common in fine jewelry with gemstones. Stronger than 22K, with a softer yellow.
14K	58.5%	585	Durable and scratch-resistant, ideal for everyday pieces and detailed designs like Şahmaran.

Questions about testing

What is XRF gold testing?

XRF (X-ray fluorescence) is a lab-grade method that reads the metal composition of jewelry. A low-energy X-ray excites the atoms in the metal, and the detector measures the signal each element sends back, giving the gold content and the other alloy metals.

Which machine do you use?

We use a Fischer GOLDSCOPE SD 510, a professional XRF analyzer made by Helmut Fischer for testing precious metals.

Is XRF better than an acid or scratch test?

XRF does not damage the piece and gives an actual percentage of gold, not just a pass or fail on a touchstone. That is why it is used by refiners and assay offices.

Can you test gold I bought somewhere else?

Yes. Bring it to the showroom and we can test it for you. It's the easiest way to confirm the karat of a piece before you sell, trade or insure it.
