Wedding rings are usually made of materials like gold and silver, which are diamagnetic and therefore have little effect on a magnetic field. This means that they are unlikely to set off metal detectors, which rely on detecting disruptions in magnetic fields. However, some metal detectors are more sensitive than others, and certain jewellery styles may be more likely to trigger them. Additionally, alloys commonly found in white gold, such as nickel, can be magnetic and may set off metal detectors.

Wedding rings are often made of gold, which is diamagnetic and has little effect on a magnetic field
Wedding rings are often made of gold, which is a diamagnetic material with little impact on a magnetic field. Gold is a popular choice for wedding bands and engagement rings due to its timeless appeal and various styles, such as yellow, rose, or white gold. However, it is typically combined with other metals to create an alloy, enhancing its durability.
Pure gold, or 24-karat gold, is the most luxurious and expensive option, but it is also the most pliable and least durable. Lower karatages, such as 14-karat or 18-karat gold, contain a lower percentage of pure gold, making them more durable and scratch-resistant. For example, 14-karat gold consists of 58.3% pure gold, while 18-karat gold contains 75%.
The style and orientation of jewelry can also play a role in setting off metal detectors. Certain pieces of jewelry with specific orientations may be less likely to disrupt the magnetic field and trigger an alarm. Additionally, the volume and type of metal in the jewelry piece contribute to its detectability.
While gold wedding rings typically do not set off metal detectors, other jewelry made of different materials, such as stainless steel, may trigger the sensors. It is worth noting that some individuals have reported their gold jewelry setting off metal detectors in combination with other metal items, such as a watch or bracelet.

The alloy of the metal is more likely to set off a metal detector than the volume of metal
Wedding rings are usually made of materials like gold and silver, which are diamagnetic and therefore have little effect on a magnetic field. This means that the alloy of the metal is more likely to set off a metal detector than the volume of the metal. For example, gold is highly conductive and will set off metal detectors that use electromagnetic fields.
The style of the jewelry also seems to make a difference. For instance, a woman wearing several chain bracelets may not set off a metal detector, but a woman with one tiny solid bangle will. Additionally, some Cape Cod bracelets alarm when they are closed but do not when they are open. This may be because an item that is oriented in the direction of the field (perpendicular) is less likely to have a detectable effect than one oriented parallel to the direction of the field.
Different scanners will also pick up different things. Some are very sensitive, while others are less so. For example, a ring made of 14k white gold may set off a walk-through metal detector, but a similar ring made of 14k gold from a local vendor may not. This is because 14k gold is about 60% gold, with other metals like steel making up the rest. While gold is not magnetic, some alloys of gold can be. For example, white gold alloys from vendors in China and the US often use nickel, which may be enough to set off certain metal detectors.

The style of jewellery can make a difference, with some items more likely to set off alarms
The style of jewellery can make a difference in whether or not it sets off metal detectors. For example, a woman wearing several chain bracelets may not trigger the alarm, while a woman with one tiny solid bangle may alarm every time. Cape Cod bracelets, for instance, tend to alarm when closed but not when open. This may be because an item that is oriented in the direction of the field (perpendicular) is less likely to have a detectable effect than one oriented parallel to the direction of the field. Additionally, the amount of metal in an item of jewellery can also determine whether or not it sets off a metal detector. For instance, a large silver cuff bracelet may set off the alarm, while a small wedding ring may not.
The alloys of the metal, rather than the total volume, are also more likely to set off metal detectors. Ferromagnetic, ferrimagnetic, and paramagnetic materials will be more readily detected than diamagnetic materials and antiferromagnetic materials. For example, shoes with steel shanks are usually at least somewhat ferromagnetic and therefore disrupt a magnetic field, while rings are usually made of materials like gold and silver that are diamagnetic and therefore have little effect on a magnetic field.
The design of jewellery can also affect whether or not it sets off metal detectors. For instance, a solid bracelet may set off the alarm, while a linked bracelet may not as there are gaps that show it is not a large piece of solid metal. Similarly, a necklace worn around the neck or wrist may not set off the metal detector, but the same item balled up in a hand or pocket may be more likely to trigger the alarm.
Furthermore, some types of jewellery may contain trace amounts of reactive metals from production, which could potentially set off metal detectors. For example, David Yurman bracelets may have a titanium cable core for added strength, and titanium is usually mixed with another metal in jewellery.

Different scanners will pick up different things, with some more sensitive than others
Wedding rings are usually made of materials like gold and silver, which are diamagnetic and have little effect on a magnetic field. This is why they do not set off metal detectors. However, different scanners will pick up on different things, and some are more sensitive than others.
The sensitivity of a metal detector varies depending on the machine. For example, some people have reported that their rings set off walk-through metal detectors, while others have said that their rings did not set off any alarms. It is possible that the walk-through metal detector that detected the ring was more sensitive than the ones that did not. Additionally, the style of the jewelry may also make a difference, as some items of jewelry may be oriented perpendicularly or parallel to the direction of the field, which affects how detectable they are.
The alloys of the metal are more likely to set off a metal detector than the total volume. Ferromagnetic, ferrimagnetic, and paramagnetic materials will be more readily detected than diamagnetic materials and antiferromagnetic materials. For example, some alloys of gold can be magnetic, and gold conducts electricity well, so it will set off metal detectors that use electromagnetic fields.
The type of metal detector also matters. For example, gold prospectors' metal detectors use magnets to detect magnetic items, so gold rings may be more likely to set them off. On the other hand, metal detectors that use electromagnetic fields are looking for materials that conduct electricity, so gold rings are more likely to be detected by these machines.

White gold and platinum are the most difficult metals for metal detectors to detect
Metal detectors are used in various contexts, from treasure hunting to security checkpoints. While they can detect a wide range of metals, from aluminium to gold, some metals are more difficult to detect than others. White gold and platinum are among the most challenging metals for metal detectors to identify.
White gold is an alloy, a combination of metals. It is made by mixing gold with other metals such as nickel, palladium, or silver. This alloy is popular in jewellery for its strength and durability, in addition to the allure of gold. However, its composition makes it harder to detect than pure gold. To successfully detect white gold, a PI (Pulse Induction) metal detector is recommended. This type of detector is more sensitive to gold and gold alloys.
Platinum is another metal that can be elusive to metal detectors. To increase the chances of finding platinum, it is advisable to search in populated areas like beaches or parks, as these locations are more likely to yield platinum items. While platinum is challenging to detect, it is not impossible. Metal detectors can find platinum, especially with modern technology that offers better adaptability.
The style and orientation of jewellery also play a role in detection. For example, a solid gold bracelet might set off a metal detector, while a gold ring may not. Additionally, an item that is oriented perpendicularly to the direction of the magnetic field is less likely to trigger a detector than one oriented parallelly.
It is worth noting that metal detectors have different capabilities, and some are designed for specific purposes. For instance, gold prospecting detectors are highly sensitive to small pieces of gold, while general-purpose models are less likely to detect objects as small as a grain of rice. Higher-frequency detectors can detect smaller metals but may struggle with non-ferrous metals. Therefore, the type of metal detector and its settings can significantly impact the detection of white gold and platinum.
