What Does “Q” Mean on Gold Jewelry?
When you look closely at your gold jewelry, you might notice small letters or symbols engraved inside — marks like 10K, 14K, or even a “Q”. These tiny imprints are more than decoration; they reveal essential details about the purity, origin, or maker of the piece. One question many people ask is: what does “Q” mean on gold jewelry?
Let’s explore the meaning behind the “Q” marking, how to identify its context, and what it tells you about your jewelry’s authenticity and gold content, especially if you’re buying or selling in New Zealand or Texas.
Understanding Gold Jewelry Markings
Before we focus on the letter “Q,” it’s important to understand why gold jewelry has markings in the first place. These are called hallmarks or maker’s marks, and they serve as identifiers for:
Gold purity (e.g., 10K, 14K, 18K, 24K)
Manufacturer or jeweler’s initials
Location or assay office symbols
Quality or authenticity certification
If you’ve ever wondered how to interpret all these engravings, our guide on how to know what your jewelry is provides a detailed breakdown of gold stamps and what they represent.
What Does the “Q” Mark Mean on Gold?
The meaning of “Q” on gold jewelry can vary depending on where the piece was made and by whom. Here are the three most common interpretations:
1. “Q” as a Manufacturer’s Mark
In many cases, the “Q” represents a maker’s or jeweler’s signature, identifying the brand or manufacturer behind the jewelry. For instance, some jewelers stamp their initials or a single identifying letter to mark authenticity.
If you see a “Q” followed by other letters (like “QT” or “QG”), it usually stands for a specific company. For example:
QG often represents Quality Gold Inc., a well-known U.S.-based manufacturer.
QT can denote Quality Trends, another jewelry brand marking.
In these cases, the “Q” isn’t related to the purity of the gold, but to who made it.
2. “Q” as a Purity or Alloy Indicator
In some gold jewelry, particularly older or international pieces, the letter “Q” might also appear near a karat marking like “14K Q” or “18K Q.” This can refer to a specific gold alloy blend or quality classification used by certain refiners.
For example, “14K Q” could indicate that the piece is 14 karat gold produced using a proprietary alloy formula by a maker whose brand code includes “Q.”
To understand how alloys affect color and strength, you can read what colors make gold — it explains how metals like copper, silver, and zinc influence tone and durability.
3. “Q” as a Quality Stamp
Occasionally, “Q” can represent Quality Gold — not as a brand, but as a guarantee of high-quality metal content. In the U.S. and other markets, this may have been an informal trade practice among manufacturers.
However, if you’re in New Zealand, gold jewelry usually follows karat and purity stamps rather than single-letter codes. For example, you’re more likely to see 375 (9K) or 750 (18K) instead of a “Q” mark. Learn more about gold quality standards in our guide which gold is best for jewellery in NZ.
How to Verify What the “Q” Means on Your Jewelry
If you’re unsure what the “Q” on your ring, bracelet, or chain means, here’s how to find out:
Check for other hallmarks — Look for numbers like 10K, 14K, or 18K alongside the letter. That will clarify purity.
Inspect the logo or initials — “Q” may appear next to a full maker’s mark such as “QG,” “TJ,” or “QTR.”
Consult a professional — A certified gold buyer or jeweler can test and identify your piece’s origin.
Use acid or XRF testing — To confirm gold purity, you can have it tested in-store or learn how to test gold jewelry in NZ.
Why Markings Matter When Buying or Selling Gold
When it comes to selling gold jewelry, these small details can significantly impact its value.
Buyers and appraisers use hallmarks like “Q” or “14K” to:
