How to Tell Real Gold From Fake at Home in Pakistan — Tests That Actually Work

The short answer — and why most home tests only rule things out, not in

No home test proves a piece is real gold with certainty. Every test on this page is a screening tool — it can tell you something is definitely not gold, or that it passed one more check than a fake usually does. The only test that gives a definitive answer is a professional acid test or XRF analysis at a jeweller's counter, using reagents and equipment you do not have at home. What you can do at home is stack four or five quick checks together. If a piece fails even one, you have your answer. If it passes all of them, you have reasonable confidence — not certainty, but enough to act on.

This matters more in Pakistan than in most markets because the jewelry sold here spans an unusually wide range — from 22K traditional gold at the family jeweller, to 21K and 18K solid pieces, to gold plated stainless steel and brass fashion jewelry, often without the seller stating clearly which one you are looking at. Knowing the tests means you are not depending on the seller's word for it.

The magnet test — fast, free, and more useful than people expect

Gold is not magnetic. Neither is platinum, sterling silver, or stainless steel. A strong neodymium magnet (the small, powerful kind — a fridge magnet is usually too weak to be conclusive) held close to a piece of jewelry should show zero attraction if the piece is solid gold, gold plated on a non-magnetic base, or genuine silver.

If the piece is pulled toward the magnet even slightly, the base metal contains iron — meaning it is almost certainly not gold and not stainless steel either, since standard 304 and 316 grade stainless steel used in quality jewelry is non-magnetic or only very weakly magnetic. A strong pull toward the magnet usually points to a cheap iron-based alloy with a thin gold-coloured coating, the lowest tier of fashion jewelry.

The magnet test rules things out — it does not rule things in. A piece that does not react to a magnet could be solid gold, could be gold plated stainless steel, could be gold plated brass, or could be sterling silver. All of these pass the magnet test. None of them fail it except the iron-based fakes. This is why the magnet test is step one, not the whole answer.

The float test — works on solid gold only, gives a false fail on every plated piece

Drop the piece into a glass of plain water. Solid gold is dense enough that it sinks quickly and sits flat on the bottom — it does not float, tilt, or hover partway down. This test is genuinely useful for solid gold jewelry, particularly older or inherited pieces with no markings.

The float test gives a misleading result on gold plated jewelry. A stainless steel base with 18K PVD coating will also sink — stainless steel has a density close to many gold alloys — so the float test alone cannot distinguish solid gold from a well-made plated piece on stainless steel. It is only useful for ruling out gold-plated jewelry built on lightweight bases like aluminium or certain plastics, which is rare in the Pakistani market but does occasionally appear in very cheap fashion pieces.

The hallmark and stamp check — what the numbers actually mean

Genuine solid gold sold in Pakistan should carry a hallmark stamp indicating purity — commonly 999 for nearly pure gold, 916 for 22K, 875 for 21K, or 750 for 18K. These numbers represent parts per thousand of pure gold in the alloy. A piece stamped 750, for example, is 75% gold by weight, with the remaining 25% being other metals for strength and colour.

Gold plated jewelry is marked differently, and this is where most confusion happens in Pakistan's online jewelry market. A stamp reading "18K GP" or "18K HGE" does not mean the piece is 75% gold throughout. GP stands for gold plated — a thin layer of gold, often measured in microns, applied over a base metal that makes up the overwhelming majority of the piece's weight. HGE stands for heavy gold electroplate, an older American marking convention for a thicker-than-standard plating layer, still a coating, not solid gold.

The honest reading of any stamp: if it says solid, fine, or gives only a karat number with no plating qualifier, the seller is claiming solid gold. If it says plated, GP, HGE, vermeil, or filled, the piece has a gold layer over a base metal, and the karat number describes the colour and purity of that surface layer only — not the composition of the whole piece.

The skin and makeup test — unreliable, but worth knowing why

A common claim online is that rubbing a piece against makeup foundation (which often contains iron oxide) and checking for a black streak determines gold purity. This test produces inconsistent results and is not something to rely on. The chemistry behind it is real — some metals do react with the iron oxide and skin oils to leave a mark — but the result varies too much by skin chemistry, foundation formula, and metal composition to function as a reliable home test. It is mentioned here only because it is searched often; the honest answer is that it does not hold up well enough to base a decision on.

Where gold plated jewelry actually sits on the authenticity spectrum

This is the part most home-test guides skip, and it matters more than any single test. Gold plated jewelry is not fake gold and it is not pretending to be solid gold — when sold honestly, it is its own category with its own value proposition. The dishonesty problem in the market is not the existence of gold plated jewelry, it is sellers who let buyers assume "gold plated" means something closer to solid gold than it does, or who do not disclose the base metal at all.

Category	What it actually is	Honest price range Pakistan	What a "real gold" test tells you
Solid gold (22K, 21K, 18K)	Gold alloy throughout the piece	Rs 25,000+ depending on weight and karat	Should pass magnet, float, and hallmark checks fully
Gold filled	Mechanically bonded gold layer over base metal, much thicker than plating	Rs 5,000–15,000	Passes magnet test (non-magnetic base); float test inconclusive
18K PVD gold plated (stainless steel base)	Molecularly bonded gold coating over stainless steel	Rs 1,500–4,500	Passes magnet test; float test inconclusive; correctly stamped GP
Standard electroplated (brass base)	Thin gold layer over brass or zinc alloy	Rs 200–1,500	Passes magnet test; coating wears fast, base shows through quickly
Iron-based fashion fakes	Gold-coloured paint or coating over an iron alloy	Rs 100–500	Fails the magnet test — this is the piece these tests catch

The magnet and float tests primarily catch the bottom tier — the iron-based pieces sold as gold-coloured fashion jewelry with no real plating process at all. They cannot distinguish a quality 18K PVD stainless steel piece from solid gold, because both are non-magnetic and both sink. That distinction comes from the price, the stated base metal, and the seller's transparency — not from a home chemistry test.

What this means when you are buying online in Pakistan

The home tests on this page are most useful for checking jewelry you already own — inherited pieces, old purchases with no clear documentation, or items bought in person where you cannot verify the seller's claims afterward. For an online purchase, the test happens before you buy, not after: does the listing state the base metal, does it specify the plating method, does the price match the category it claims to be in. A listing for an "18K gold" necklace at Rs 800 is not offering solid gold at a discount — it is almost certainly describing the karat colour of a plated piece while omitting the word plated, whether deliberately or carelessly.

For the specific terminology confusion between artificial, gold plated, and imitation jewelry — and which honest category Mithra's pieces fall into — the terminology guide breaks down exactly what each label legally and practically means.

For how to verify the specific claims a seller makes about plating method and durability before completing an online order, the honest buying guide covers the checklist of questions worth asking and what answers should make you walk away.

Where Mithra's collections sit

Every piece at Mithra & Co is 18K PVD gold plated over a 316L stainless steel base — stated plainly, never described as solid gold, never priced to suggest otherwise. The magnet test on any Mithra piece will show no attraction, consistent with the stainless steel base. The float test will show the piece sinking, consistent with stainless steel's density. The honest category is gold plated, and the honest price reflects that category.

Frequently asked questions

Q1. Does the magnet test prove jewelry is real gold?

A: No — it only proves the piece is not built on an iron-based alloy. Gold, stainless steel, brass, and sterling silver are all non-magnetic, so a piece passing the magnet test could be solid gold or could be a quality gold plated piece on a non-magnetic base. The magnet test catches the cheapest iron-core fakes; it cannot distinguish solid gold from well-made plated jewelry.

Q2. What does 18K GP mean on a jewelry stamp in Pakistan?

A: GP stands for gold plated. The piece has a gold coating, typically measured in microns, applied over a base metal — usually stainless steel or brass — that makes up the vast majority of the item's weight and structure. The "18K" describes the karat purity of the surface gold layer only, not the composition of the whole piece. This is different from a stamp that simply says "18K" with no qualifier, which is a claim of solid 18-karat gold throughout.

Q3. Will real gold sink or float in water?

A: Solid gold sinks quickly and sits flat at the bottom of a glass of water due to its high density. This test reliably rules out lightweight fakes such as aluminium or plastic-core jewelry. It does not reliably distinguish solid gold from gold plated stainless steel, since stainless steel has a density close enough to many gold alloys that both will sink in the same way.

Q4. Is gold plated jewelry considered fake gold in Pakistan?

A: Not when sold honestly. Gold plated jewelry is a distinct, legitimate category — a real gold coating over a base metal, sold at a price that reflects that construction. It becomes a problem only when sellers misrepresent it as solid gold or omit the base metal entirely. The dishonesty is in the disclosure, not in the existence of plated jewelry as a product category.

Q5. What is the most reliable way to check gold purity at home in Pakistan?

A: No single home test is fully reliable — the magnet test, float test, and hallmark check work best stacked together, and even then they only narrow the possibilities rather than confirm purity definitively. For a piece with real financial stakes, a professional acid test or XRF scan at a jeweller's counter gives a far more conclusive answer than anything that can be done with household items.

Q5. Where can I buy honestly labelled gold plated jewelry in Pakistan?

A: Mithra & Co states the base metal and plating method on every product listing — 18K PVD coating over 316L stainless steel, with no solid gold claims and pricing that reflects the plated category honestly. Browse the full collection at mithraofficial.com with cash on delivery across Pakistan.
