Understanding Gold Purity and Alloys
When diving into the world of fine jewelry, a common question arises: Is 750 white gold? To answer this inquiry, we must first grasp the basics of gold purity and the various alloys used in crafting beautiful pieces. Gold purity is measured in karats (K), with pure gold being 24K. However, most jewelry contains a percentage of other metals, which creates different variants of gold.
In the jewelry-making industry, the term “750” refers to a specific purity level of gold: 75% pure gold, also known as 18K. The remaining 25% consists of other metals that contribute to the overall appearance, strength, and color of the gold. It’s essential to know that while 750 is indeed a measure of gold purity, it does not indicate white gold directly.
What is White Gold?
White gold is an alloy created by combining yellow gold with other metal(s) to achieve a lustrous, silver-like hue. The primary metals used for this transformation usually include:
- Palladium
- Nickel
The alloy typically starts with yellow gold of varying karat levels, which may include 10K, 14K, 18K (750), or even higher karats. However, it’s crucial to note that the look and characteristics of white gold largely depend on the metals blended into the yellow gold.
The Making of White Gold
Creating white gold involves several steps that can be summarized simply:
- Alloying: Yellow gold is combined with white metals, often in varying percentages.
- Melting: The components are heated until they become molten.
- Forming: The molten gold is cast into molds or drawn into wire.
- Finishing: The resulting white gold piece may be plated with rhodium to enhance its white sheen and protect it from scratches.
This transformation not only alters the color but also the properties of the metal, including its hardness, durability, and ability to resist tarnishing.
Is 750 White Gold? Understanding 750 White Gold Compositions
While 750 represents the purity level of gold, it does not specify the color. A 750 white gold alloy will consist of 75% gold and 25% other metals. Thus, 750 white gold is a valid term, but it is not synonymous with pure white gold, as the appearance is largely defined by the metals chosen for the alloy.
However, the actual composition of a 750 white gold item can differ based on individual jewelers or manufacturers. Here are some common configurations:
Common Alloys in 750 White Gold
| Alloy | Composition | Properties |
|---|---|---|
| Palladium | 75% Gold, 25% Palladium | Hypoallergenic, durable, expensive |
| Nickel | 75% Gold, 25% Nickel | Durable but can cause allergic reactions |
With these metals in the mix, 750 white gold can exhibit various characteristics. Palladium-based alloys are preferred for their hypoallergenic properties, while nickel can significantly reduce costs but may trigger allergic reactions in sensitive skin.
Distinguishing Between 750 White Gold and Other Types
When purchasing jewelry, it’s vital to distinguish between 750 white gold and other variations such as:
- 950 White Gold: Composed of 95% pure gold and 5% palladium or nickel, resulting in a more luxurious, heavier feel.
- Fine Gold: Refers to 24K gold, which is purely gold without any alloys—often too soft for jewelry on its own.
The differences in composition can lead to variations in strength, appearance, and price.

What does 750 mean in relation to white gold?
The term “750” denotes the purity of gold used in jewelry, specifically that the alloy is made up of 75% pure gold. This means that in a 1000 parts of the alloy, 750 parts are made of pure gold, while the remaining 250 parts are comprised of other metals. The number is derived from the metric system where the purity of gold is often expressed in parts per 1000. Thus, 750 white gold is considered 18-karat gold, which is a popular choice for fine jewelry due to its balanced combination of beauty and durability.
The remaining percentage usually includes metals such as palladium, nickel, or silver, which not only help to whiten the gold but also enhance its strength and scratch resistance. It’s important to note that the presence of these metals can affect the color and overall appearance of the jewelry. For people with sensitive skin, it’s advisable to check whether nickel is present, as it is a common allergen.
Is 750 white gold the same as platinum?
No, 750 white gold and platinum are not the same, and they have distinct properties. While 750 white gold contains 75% pure gold and is alloyed with other metals, platinum is a naturally occurring precious metal that is denser and has a different composition. Platinum is typically purer than gold alloys, with common purities ranging from 85% to 95% (850 to 950 platinum). This inherent purity gives platinum a distinctive color and durability that is different from that of white gold.
<pFurthermore, platinum is often more expensive than 750 white gold due to its rarity and density. It is less likely to wear down over time, meaning platinum jewelry can maintain its quality for many years with minimal upkeep. In contrast, while 750 white gold is elegant, it may require periodic re-plating with rhodium to retain its bright white finish and combat the natural yellowing of the gold over time.
