Common Markings on Jewelry
When it comes to jewelry, there are a variety of markings that can be found on pieces. These markings can indicate the metal content, purity, manufacturer, and more. Here are some of the most common markings found on jewelry:
Hallmarks
Hallmarks are symbols or marks stamped on jewelry that indicate the metal content and purity. In the United States, hallmarks are not required by law, but some manufacturers choose to include them. In other countries, such as the United Kingdom, hallmarks are mandatory. Hallmarks can include the metal type, purity, and year of manufacture.
Metal Stamps
Metal stamps are markings that indicate the metal type used in the piece of jewelry. For example, "925" indicates sterling silver, "14K" indicates 14-karat gold, and "PT" indicates platinum.
Purity Marks
Purity marks indicate the percentage of pure metal in the piece of jewelry. For example, "18K" indicates 75% pure gold, while "14K" indicates 58.3% pure gold.
Manufacturer's Marks
Manufacturer's marks are symbols or initials that indicate the company or individual who made the piece of jewelry.
Trademark Symbols
Trademark symbols indicate that the piece of jewelry is protected by a trademark. This can include the company name or logo.
Designer Marks
Designer marks indicate that the piece of jewelry was designed by a specific person or company.
Engravings and Monograms
Engravings and monograms are personalized markings that can be added to jewelry. These can include names, dates, or special messages.
Remember to always check the markings on your jewelry to ensure its authenticity and value.
Hallmarks
One important type of marking on jewelry is the hallmark. A hallmark is a symbol or series of symbols stamped onto a piece of jewelry that indicates the metal content, purity, and sometimes the maker of the piece. Hallmarks are used to ensure that jewelry is of a certain quality and meets certain standards.
Hallmarks have a long history, dating back to the 14th century. They were originally used to indicate the quality of silver, but later came to be used for other metals as well. In the United States, the Jewelers Vigilance Committee is responsible for ensuring that jewelry hallmarks are accurate and truthful.
Some common symbols that may be found on hallmarks include:
- A number indicating the metal content (e.g. 925 for sterling silver)
- A symbol indicating the purity of the metal (e.g. a lion for British sterling silver)
- A trademark or maker's mark indicating the company or individual who made the piece
To identify hallmarks on jewelry, a magnifying glass may be necessary. It is important to note that not all jewelry will have hallmarks, particularly vintage pieces.
Metal Stamps
Metal stamps are markings on jewelry that indicate the type of metal used in its construction. The markings are typically found on the inside of the band or on the clasp of a necklace or bracelet. Metal stamps are an important way to identify the quality and purity of a piece of jewelry.
The National Gold and Silver Stamping Act requires that all gold and silver jewelry sold in the United States be stamped with a quality mark. The quality mark indicates the gold purity or fineness of the metal. The fineness is measured in parts per thousand, with 24 karat gold being 1000 parts pure gold.
Silver electroplate is a type of jewelry that is made by coating a base metal with a thin layer of silver. The metal stamp on silver electroplate jewelry will typically indicate the base metal used, such as copper or brass, followed by the letters EP for electroplate.
Non-precious metals, such as German silver or nickel silver, are commonly used in jewelry making. These metals are alloys that may contain copper, zinc, and nickel. The metal stamp on jewelry made from non-precious metals will typically indicate the type of metal used, such as German silver or nickel silver.
Goldsmiths often use alloy metals to create jewelry that is more durable and affordable than pure gold. The metal stamp on this type of jewelry will indicate the purity of the gold used, as well as the type of alloy metal used.
Purity Marks
Purity marks are used to indicate the precious metal content of jewelry. These marks can help you determine the value of a piece of jewelry and whether it is made of a precious metal or not.
The most common purity marks you may come across are karat markings for gold and fineness markings for silver. Karat markings indicate the percentage of pure gold in a piece of jewelry. For example, 24 karat gold is 100% pure gold, while 18 karat gold is 75% pure gold.
Fineness markings are used for silver and indicate the percentage of pure silver in a piece of jewelry. For example, a fineness mark of .925 means that the piece is made of 92.5% pure silver.
Other common purity marks you may see include:
- GF: This stands for gold filled and means that a layer of gold has been bonded to a base metal.
- Plat: This indicates that the piece is made of platinum.
- Silver-plated: This means that a layer of silver has been applied to a base metal.
- CZ: This stands for cubic zirconia and indicates that the stone in the piece is not a real diamond.
It is important to note that the appearance of a piece of jewelry does not always indicate its purity. Some pieces may be coated with a layer of gold or silver to give them a certain look, but this does not necessarily mean that they are made of a precious metal.
Manufacturer's Marks
Manufacturer's marks are one of the most common markings found on jewelry. These marks usually indicate the company or individual who made the piece of jewelry. They can be found on any type of jewelry, from rings to necklaces to bracelets.
Manufacturer's marks can take many different forms, including:
- A company name or logo
- An individual's initials or signature
- A symbol or emblem that represents the manufacturer
These marks can be very helpful in identifying the origin of a piece of jewelry. They can also provide valuable information about the quality and craftsmanship of the piece.
In some cases, manufacturer's marks may be accompanied by other markings, such as:
- A metal purity mark
- A country of origin mark
- A date mark
All of these markings can provide important clues about the history and value of a piece of jewelry.
Trademark Symbols
Trademark symbols are used to indicate that a particular design, logo, or phrase is a registered trademark. These symbols are important because they help protect the intellectual property of the company or individual who owns the trademark.
There are three trademark symbols that are commonly used:
- ™ - This symbol is used to indicate that a particular design, logo, or phrase is a trademark, but it is not yet registered with the US Patent and Trademark Office (USPTO).
- ® - This symbol is used to indicate that a particular design, logo, or phrase is a registered trademark with the USPTO. Only trademarks that have been officially registered with the USPTO are allowed to use this symbol.
- © - This symbol is used to indicate that a particular work, such as a piece of jewelry, is protected by copyright law. This symbol is used to indicate that the work is an original creation and cannot be copied without permission.
It is important to note that the use of these symbols is regulated by law. It is illegal to use the ® symbol if a trademark has not been officially registered with the USPTO. Additionally, it is illegal to use the ™ symbol if a trademark has not been established.
Designer Marks
Designer marks are one of the most significant markings on jewelry. They indicate the designer who created the piece and add value to the jewelry. Some of the most popular designer marks are:
Paloma Picasso
Paloma Picasso is a famous jewelry designer who has designed for Tiffany & Co. and her own brand. Her signature is a stylized "P" with a horizontal line crossing the loop. This mark is often found on her jewelry pieces.

David Yurman
David Yurman is a designer who creates unique pieces of jewelry. His mark is his signature, which is often found on his pieces. His signature is a stylized "DY" that is easily recognizable.
Designer marks are an essential aspect of jewelry. They indicate the designer who created the piece and add value to the jewelry. Popular designer marks include Paloma Picasso, Cartier, and David Yurman.
Engravings and monograms are some of the most common markings found on jewelry. These markings are usually etched onto the surface of the jewelry, and can provide important information about the piece. Here are some things to look for when examining engravings and monograms on jewelry:
- Initials: Many pieces of jewelry, especially those given as gifts, are engraved with the initials of the recipient. These initials may be the recipient's own initials, or they may be the initials of a loved one or family member.
- Dates: Jewelry may also be engraved with important dates, such as birthdays, anniversaries, or other special occasions. These dates can provide important clues about the history of the piece.
- Symbols: Engravings may also include symbols, such as hearts, stars, or other decorative motifs. These symbols may have personal meaning to the wearer, or they may simply be decorative.
- Makers' Marks: Some jewelry may be engraved with the mark of the maker or manufacturer. These marks can provide important information about the origin and authenticity of the piece.
- Hallmarks: In some cases, jewelry may be engraved with a hallmark, which indicates the metal content of the piece. For example, a piece of gold jewelry may be engraved with a "14K" hallmark, indicating that it is made of 14 karat gold.
Conclusion
Engravings and monograms can provide important information about the history and authenticity of a piece of jewelry. By examining these markings closely, you can gain a better understanding of the story behind the piece.
