How to Test Gold with Lighter at Home?

Gold is expensive because it is uncommon. With its metallic qualities and golden yellow hue, it is stunning. Unlike many other metals, it can withstand corrosion and may be shaped into various forms.

It may be used to create robust, weighty, delicate goods with embellishments. It is adaptable and has various uses in chemistry, manufacturing, and electronics. People have attempted to duplicate gold for its worth, particularly when making jewelry. You’ll need to have a technique to find out since you may be unable to tell with your naked eye.

There are several tests to do to find out. One test is the simpler test, and it works well. Continue reading to learn how to use a lighter to verify the authenticity of gold jewelry, so try to burn your gold, which is the first and simplest exam. Even though it will shine brighter when the flame is applied, genuine gold won’t truly burn or catch fire. You most likely have counterfeit gold if your gold item begins to smoke or darken.

Why does it work?

Genuine gold does not burn or become black when heated. It simply melts, which explains how it can be sculpted and molded into many shapes without losing its shine or gorgeous yellow-gold hue.

As opposed to this, other metals like copper, iron, and brass will darken and change color when exposed to flame. If your object is gold-plated, the gold will melt and reveal the darker metal underneath.

How to Tell if Gold is Real with Lighter?

Color change or Absence of these changes

You must observe the gold piece’s impact on the flame during this test to determine whether a reaction occurred. You can tell whether a piece is made of solid gold with no pull from the flame or just a very tiny draw. Observe any variations in hue and record them as well.

The item being examined is probably a fake if it darkens or changes color when exposed to the lighter. If the jewelry is made of actual or solid gold, there won’t be any color changes. When exposed to a lighter, pure gold jewelry shines brighter and never darkens. Therefore, if a piece of jewelry darkens, it is probably composed of brass, iron, copper, or faux gold. A milky or greenish stain on the gold suggests that the item is either false gold jewelry or maybe sterling silver with gold plating.


Melting Gold is Fake

The second thing you should pay attention to is how gold jewelry reacts to the lighter’s flame in terms of color and behavior. In essence, a piece of jewelry that has been gold-plated will exhibit traces of the thin coating of gold melting when the substance underneath is revealed.

Follow these easy steps to do this test:

  • First, ensure you use a lighter that consistently produces a large flame rather than a disposable lighter, particularly if the flame is irregular. Additionally, you must ensure that the lighter well is only filled with lighter fluid and not any other fuel.
  • When the flame is just right, you should hang the jewelry on something metallic or another material that won’t melt or burn. To lessen the possibility of the jewelry being harmed, you might also use pliers as long as the ends are protected.
  • Once you’ve prepared everything, apply or hold the gold jewelry close to the flame. After holding the flame on the gold jewelry for a minute, look for any changes and record them. If the gold item oxidizes, it is presumably composed of gold plating rather than solid gold. It is constructed of genuine gold if it doesn’t change hue or acquire a brighter golden luster.

Remember that results may vary significantly for gold pieces with a purity level below 18k. You will notice that the color of the gold changes slightly and that it is slightly attracted to the flame. This raises doubt.

Therefore, you may wish to have the jewelry examined by a specialist who can do tests like the nitric acid test or other more dependable and precise procedures. That stated, while doing this test, you shouldn’t expose the gold jewelry to a particularly hot or powerful flame, such as the flame from a blow torch, since the blowtorch may harm the jewelry. Gold melts comparatively quicker than other metals at a high temperature.


You can determine if a piece of jewelry is composed of genuine gold by how it responds to the flame of a lighter. The jewelry’s color shift proves that it is genuine gold, in contrast to false gold, which becomes deeper and darker with time, and after being exposed to flames, real gold does not undergo a color change.
