Before You Buy Another Gold or Silver Bar in Dubai — Read This First
By Telos Instruments | Exclusive Sigma Metalytics Distributor in the GCC | Dubai, UAE
Sigma Metalytics PMV Investor — Full-depth gold and silver bar authentication
You have done your homework. You checked the gold rate, bought from a reputable dealer, looked for the hallmark, asked for the certificate. You did everything correctly. And you still cannot be completely certain what is inside that bar. This guide is not about scaring you away from buying gold in Dubai — it’s about the one step that almost every personal gold investor in the GCC skips — and what happens when you do not skip it.
Investment-grade gold bars and coins (99.5%+ purity) are zero-rated for VAT in the UAE. No capital gains tax, no wealth tax, no inheritance tax. The UAE is home to top refiners like Al Etihad Gold, Emirates Gold, and SAM Precious Metals. Gold bars from 1g to 1kg offer substantial investments, and coins like Maple Leafs or Krugerrands are easy to trade. But “largely trustworthy” is not the same as “completely certain.”
Tungsten has a density almost identical to gold — 19.25 g/cm³ vs gold’s 19.30 g/cm³. A bar with a tungsten core surrounded by genuine gold will weigh correctly, look correct, and pass surface tests (including XRF). Because XRF only reads the surface — never reaching the core. The certificate is genuine. The hallmark is genuine. The bar is not.
You have done steps 1–5. Now do the one thing that takes thirty seconds and tells you what the certificate cannot: verify that the metal inside the bar matches the metal on the surface. The Sigma Metalytics PMV Investor is the instrument that does this. It generates an electromagnetic field that passes through the entire bar — from front face through the core to the back — and measures the bulk resistivity. Gold’s signature is unique. Tungsten’s is different. The PMV detects the difference in seconds.
Sigma Metalytics PMV Investor

PMV Original vs. Investor
- PMV Original: surface + shallow depth — good for coins
- PMV Investor: through-depth up to 10mm + density — essential for bars
- Silver bars are thicker — Investor is the minimum standard for silver
The PMV Investor is one of the most valuable investments a gold or silver holder can make. A single 100g gold bar in Dubai represents a significant sum. A 1kg gold bar represents a very substantial portion of any personal portfolio. The PMV Investor authenticates every bar and coin you ever buy, for the lifetime of the instrument. If it prevents you from accepting a single counterfeit bar in your lifetime — it has paid for itself completely. Everything after that is protection you received for free.

Can XRF detect a tungsten core?
No. XRF only reads the surface layer. The PMV Investor reads through the full depth.
Will the PMV Investor damage my bars?
No. Non-destructive. Tests through sealed packaging — assay cards stay sealed.
Can it test silver bars?
Yes. Tests gold, silver, platinum, palladium. Silver bars (often thicker) need the Investor’s through-depth capability.
How long does each test take?
Less than 2 minutes per bar — including both resistivity and density tests.
