When discussing gold, the image of its classic warm and sunny hue often comes to mind. However, there is more than one color variation of this precious metal: white gold. Despite skepticism surrounding its value, white gold can be just as stunning, authentic, and valuable as its yellow counterpart. Beyond color, what sets these two metals apart? Let’s explore the major distinctions between yellow gold and white gold.
Understanding Gold: Formation and Varieties
Gold, cherished for its untarnishable nature and rarity, has maintained its status as one of the world’s most prized materials for centuries. Yet, before it adorns any finger, gold undergoes several stages. To grasp the disparity between white gold and yellow gold, it’s essential to comprehend the gold-making process and the diverse types of gold jewelry on the market today.
Gold Alloys
Contrary to its perception as a sturdy metal, pure gold is remarkably soft and pliable. To fashion wearable pieces, jewelers blend gold with tougher metals, creating what is known as a gold alloy. These alloy metals can alter gold’s texture, color, and chemical attributes. However, it’s crucial for jewelers to strike a balance between the properties of the alloy and the inherent value of gold. Consequently, the metal alloy content must range between 0% (pure 24-karat gold) and 58.3% (10-karat gold) to qualify as gold. Depending on the desired outcome, jewelers often incorporate one or more of the following alloy metals:
- Platinum
- Silver
- Nickel
- Iron
- Palladium
- Copper
- Zinc
- Titanium
Types of Gold
The transformation of pure gold into various shades hinges upon the alloy formula employed. Initially, all raw gold emerges as yellow. The minimal usage of alloy metals retains gold’s sunny hue, while increased alloy content facilitates the creation of an array of captivating colors. Here are the primary gold types resulting from the alloy process:
1. Yellow Gold
To preserve its characteristic warm tone, raw gold necessitates minimal alloy metal. Jewelers typically employ small percentages of copper and silver to produce stable yellow gold from its pure form. While pure yellow gold (also known as 24 karat gold) can be utilized in jewelry, its softness poses a risk for everyday wear.
2. White Gold
Many jewelers blend raw gold with titanium and nickel to produce white gold. These alloys dilute the yellow shade, yielding a clean and striking “white” color (note that any alloy besides copper will whiten natural gold). However, some wearers may experience allergic reactions to unplated gold-nickel alloy wedding bands. Palladium serves as a hypoallergenic alternative, albeit slightly less hardening.
3. Rose Gold
Copper and silver alloys contribute to the romantic pinkish hue of rose gold. Once considered a vintage style, rose gold has witnessed a resurgence in popularity in recent times.

Differences in Strength and Maintenance
While both white gold and yellow gold are esteemed metals for jewelry, they vary significantly in strength. Owing to its higher alloy content, white gold jewelry boasts greater resistance to dents, scratches, and damage compared to yellow gold. For individuals with an active lifestyle, white gold may offer a safer choice. Nonetheless, yellow gold presents its own advantages, including ease of resizing and absence of plating.
Maintenance Needs
1. Plating
Some manufacturers apply rhodium plating to white gold for added strength and luster. This silvery metal is resistant to oxidation and erosion, enhancing the cool tones of white gold. While rhodium plating safeguards against nickel allergies and scratches, it necessitates annual replating, which can be costly. Yellow gold, on the other hand, does not undergo rhodium plating as it dulls the yellow color.
2. Polishing
Yellow gold, being more susceptible to damage, often requires frequent polishing and buffing. Conversely, white gold, especially rhodium-plated variants, demands less frequent polishing, typically once or twice per year.
3. Resizing
The softness of yellow gold facilitates easy resizing of rings. In contrast, the harder structure of white gold may pose challenges during resizing.

In the realm of jewelry, pricing is contingent upon quality, encompassing both metals and gemstones. Fortunately, gold’s quality is quantifiable by its purity, denoted by the karat. A higher karat value signifies a greater proportion of pure gold, thereby elevating the price. Conversely, a lower karat value indicates a lesser quantity of pure gold, resulting in more affordable jewelry. Both white and yellow gold span various karat values, categorized as follows:
1.24 Karats:
This denotes the highest purity level, with at least 99.7% pure gold. As it lacks alloys, only yellow gold can attain the 24K designation. However, its extreme softness renders it impractical for everyday jewelry. Pure 24K gold typically costs around $59 per gram.
2.18 Karats:
An 18K piece comprises 75% gold. Both white and yellow gold can achieve this karat level due to the presence of alloys. While 18K white gold may appear less pristine than lower karat variants, both types are priced at approximately $44 per gram.
3.14 Karats:
A 14K piece contains 58.3% gold or 14 parts gold to 10 parts other metals. At this karat level, both white and yellow gold exhibit enhanced durability due to the increased alloy content. On average, 14K gold costs around $34 per gram.
4.10 Karats:
The lowest purity level, 10K gold comprises just 41.7% gold. Any karat value lower than this is not legally recognized as gold by the US government. While 10K yellow gold may lack luster, it can produce a particularly bright white gold alloy. As a budget-friendly option, 10K gold typically costs around $25 per gram.
In summary, both white and yellow gold offer reasonably priced options in the realm of precious metals. While surpassing the value of sterling silver jewelry, they remain considerably more affordable than titanium or platinum counterparts.
