What Kinds of Jewelry Contain the Most Gold by Weight?
Items that contain the most gold by weight are those that are made from 24-karat gold or are as close to pure gold as possible. However, these items might not be very common due to the softness of pure gold. (Pure gold is 24 karats, but it's very soft and malleable, making it less suitable for jewelry that needs to withstand daily wear.)
More commonly, you'll find items made from 18-karat (75% gold) or 14-karat (58.3% gold), as they strike a balance between gold content and durability. So the bottom line is that if you're looking for the highest gold content by weight, you'll want to look for items that are as close to 24-karat gold as possible.
And keep in mind that the overall value of a piece of jewelry isn't just determined by its gold content, but also its design, craftsmanship, and any gemstones that might be present.
How Can You Tell How Much Gold Is Contained in Gold-Plated Jewelry?
This can be difficult to determine without getting a test performed by an expert metallurgist/recycler like Specialty Metals Smelters and Refiners.
Why? Because gold-plated items have a thin layer of gold applied to the surface of a base metal, such as copper or silver. The gold layer could be relatively thin or thick, compared to the overall size of the item. But looking at an item or using a gold testing kit can only tell you so much about the item’s overall value. Why? Because the thickness of the gold plating cannot be determined by examining only the outside, visible surface of the piece.
Still, there are some tests you can perform before sending the item or items to Specialty Metals Smelters and Appraisers for testing.
To determine how much gold is contained in gold-plated items, you can follow these steps:
Check for Hallmarks or Stamps: Many gold-plated items will have markings or stamps that indicate the gold content. Common markings might include "GP" (for gold plated), "GF" (for gold-filled), or a number followed by "K" indicating the karat of the gold layer (e.g., 18K). These markings might be found on the clasp, inside of rings, or other inconspicuous places.
Do a Magnet Test: Gold is not magnetic, so if the item is attracted to a magnet, it's likely not pure gold. However, keep in mind that some other metals used in jewelry (like silver) are also not magnetic, so this test isn't definitive.
Try a Scratch Test: A scratch test involves creating a small scratch on the item's surface and then applying nitric acid to the scratch. The reaction between the acid and the metal can help determine whether the item is gold-plated or not. However, this method is not recommended for valuable or delicate items as it can cause damage.

Remember that gold-plated items have a very thin layer of gold, so their intrinsic value is much lower compared to solid gold items. The value of gold-plated items often lies more in their aesthetics and design rather than their gold content.
