• White gold is made by mixing gold with other metals. It is often covered with rhodium to look white. Platinum is almost pure and is naturally white. Platinum is heavier than white gold. It is also stronger and lasts longer. Platinum keeps its color for a long time without much care. This makes it great for jewelry that lasts. White gold is harder than platinum and costs less. But it needs rhodium re-plating often to stay shiny and white. Platinum does not cause allergies and is good for sensitive skin. Some white gold has nickel, which can cause allergies. Platinum holds gemstones in place better. It is rare and valuable. White gold is lighter and looks stylish.

Elements Analysis

White Gold Composition

Elements analysis shows white gold is not just one metal. White gold is made by mixing pure gold with other metals. These metals can be palladium, 銀, ニッケル, 銅, or zinc. The mix makes the metal look white and strong for jewelry. Most white gold jewelry uses 18K or 14K gold. 18K white gold has 75% gold and 25% other metals. 14K white gold has about 58.3% gold and the rest is alloy metals. The karat system tells you how much gold is in your jewelry.

ヒント: Nickel-based white gold looks whiter but can cause skin allergies. Palladium-based white gold is softer and looks a little gray.

You can see the usual white gold alloy mix in the table below:

White gold recipes change to get different colors and hardness. Some jewelers add more silver for a brighter look. Others use more palladium to make it stronger. Most white gold jewelry has a thin rhodium layer on top. This layer makes it extra white and shiny. Over time, the rhodium can wear off. Then, the gold’s yellow color may show.

Elements analysis from science studies shows white gold has a mix of precious metals. Gold is always the main part, but silver and palladium can be high too. For example, one study found silver as high as 100,980 parts per billion (ppb). Palladium and gold amounts also change with the recipe.

Platinum Composition

Platinum is special because it is very pure. Most platinum jewelry has 90% 宛先 95% 白金. The rest is usually other platinum group metals like iridium, ruthenium, or palladium. Sometimes, jewelers add cobalt or copper in small amounts. You can check the purity by looking for stamps like PT950 or PT900 on your jewelry.

注記: In the United States, platinum jewelry must have at least 95% 白金 to meet quality rules.

Here is a table showing common platinum alloy mixes:

Platinum alloys use less alloy metal than white gold alloys. This high purity gives platinum its natural white color. Platinum jewelry does not need rhodium plating to look white. The metal stays bright and shiny by itself. Platinum’s natural whiteness is a big difference from white gold, which needs plating.

Elements analysis also shows platinum and gold sometimes go together in samples, but platinum is much higher in platinum jewelry. Platinum purity is checked by strict rules around the world. You can trust platinum jewelry will always have a lot of this precious metal.

Natural vs. Artificial Whiteness

White gold gets its color from mixing metals and rhodium plating. The white color is not natural and can fade when the plating wears off. Platinum is naturally white. You do not have to worry about fading or yellowing. This is important if you want jewelry that keeps its color for many years.

Summary: Elements analysis proves white gold and platinum are different in both what they are made of and how they look. White gold uses a mix of metals and surface plating. Platinum has high purity and natural whiteness. These facts help you pick the right metal for your jewelry.

蛍光X線分析計 Analysis: A Window into the Composition

XRF分析 uses a non-destructive technique to identify and quantify the elements present in a metal. When comparing white gold and platinum using XRF, the differences become clear:

• Gold Content in White Gold: White gold’s gold content is typically between 58% and 75%, depending on the karat. The remaining elements, like nickel or palladium, are added to enhance the metal’s strength and to achieve the desired color. XRF analysis can clearly reveal the exact percentage of gold and the presence of other alloying metals.

• Platinum’s High Purity: Platinum, 一方, will typically show a much higher percentage of platinum content, with minimal impurities or alloying metals. This purity is reflected in its weight and density, making platinum jewelry more substantial than white gold of the same size.

Key Differences Revealed by XRF

1. Purity Levels: XRF analysis will show that platinum is typically much purer than white gold, which often contains a mix of metals.

2. Elemental Composition: While white gold contains various metals like palladium, ニッケル, and silver, platinum’s composition is predominantly platinum, with small amounts of other metals for enhancement.

3. Density and Durability: The higher density of platinum is evident when tested with XRF. This contributes to platinum’s reputation for being more durable and resistant to wear and tear than white gold.

4. Color: XRF can also help detect the amount of rhodium in white gold, which contributes to its bright, white finish. Since platinum is naturally white, it requires no plating.

Physical Properties

Color and Appearance

When you compare platinum and white gold, you see they look different. Platinum is naturally white and has a soft gray color. This color stays the same and does not fade. You do not need to add any coating to keep platinum shiny. White gold starts as yellow gold. Jewelers mix it with other metals to make it look white. They put a thin rhodium layer on top for extra shine. This rhodium makes white gold very shiny, but it can wear off in a year or two. When the rhodium is gone, you might see a yellow color under the surface.

If you want jewelry that stays white for a long time, platinum is a good choice. White gold needs more care to keep looking bright.

Here is a table that shows how the color and shine of both metals compare:

Durability and Hardness

It is important to know how strong these metals are. Platinum is well known for being tough. If platinum gets scratched, the metal just moves but does not go away. This helps platinum jewelry keep its shape and weight for a long time. White gold is harder than platinum because it has more alloy metals. This hardness helps white gold resist scratches. But when white gold gets scratched, a small bit of metal is lost each time.

Lab tests show platinum alloys are stronger than gold alloys. Platinum can take more force before it breaks. White gold, especially 18K, is harder, so it keeps its shiny look longer. Platinum is better at fighting wear and does not rust or change color. Platinum jewelry stays the same color for years. White gold may lose its shine as the rhodium layer wears off.

Platinum jewelry is a smart pick if you want something strong and beautiful. White gold is harder but needs more care to stay shiny.

Weight and Density

You can feel the difference in weight between platinum and white gold rings. Platinum is much heavier than white gold. Platinum is about 60% heavier than white gold. This makes platinum jewelry feel solid and fancy. Some people like the heavy feel of platinum. Others like the lighter feel of white gold.

Platinum’s high density also changes how jewelers work with it. Platinum melts at a much higher heat than gold. Jewelers need special tools and skills to make platinum jewelry. The extra weight and special work make platinum jewelry cost more.

If you want a ring that feels heavy, platinum is the best pick. If you want a lighter ring, white gold is a better choice.

Maintenance and Care

White Gold Upkeep

White gold jewelry needs special care for its surface. Most pieces have a thin rhodium layer on top. This layer makes white gold shiny and bright. It also helps protect the jewelry from scratches. The rhodium can wear off after some time. If you wear your ring every day, the layer may fade faster. Experts say you should check your jewelry every year or two. You might need to re-plate it every year if you wear it a lot. If you wear it less, the rhodium can last up to five years. Washing hands, using lotion, or being active can make the layer wear out sooner.

ヒント: Check and re-plate your white gold often to keep it shiny.

White gold sometimes has nickel in it. Nickel can bother people with sensitive skin. Many women have nickel allergies. If you are allergic, your skin may turn red or itch. Some jewelers use palladium instead of nickel. Palladium is safer for people who have allergies.

Platinum Upkeep

Platinum jewelry is easy to take care of. You do not need to worry about plating or color fading. Platinum is white by itself and does not tarnish. It stays shiny for many years, even if you wear it every day. You only need mild soap and water to clean it.

Platinum is hypoallergenic. This means it almost never causes skin problems. Its high purity makes it safe for people with sensitive skin. You can wear platinum every day without getting a rash.

Platinum gets a soft finish called patina over time. Many people like this look. If you want your jewelry to shine again, a jeweler can polish it.

注記: Platinum jewelry stays beautiful for a long time and needs little care.

White Gold and Platinum Comparison

Jewelry Settings

When you choose a ring or pendant, you want your gemstones to stay secure. The metal you pick can make a big difference. A large study by jewelry experts tested how well different metals hold stones. They found that platinum holds gemstones more securely than white gold. Platinum has better wear resistance, so the prongs and settings do not wear down as quickly. This means your diamonds or other stones are less likely to fall out over time.

White gold is still strong and works well for many jewelry designs. Jewelers like it because it is easy to shape into detailed patterns. You see white gold in many modern and classic styles. しかし, platinum jewelry is the top choice for settings that need to last a lifetime. If you want a ring with many small stones or a design with thin prongs, platinum gives you extra peace of mind.

ヒント: For heirloom pieces or rings you wear every day, platinum offers the best security for your gemstones.

Comfort and Wearability

You will notice a difference in how white gold and platinum feel on your finger. Platinum rings feel heavier because platinum is denser than white gold. Some people like this solid, weighty feel. Others prefer the lighter touch of white gold, especially if they wear several rings at once.

Comfort depends on more than just the metal. ザ width and thickness of the band also matter. Wider or thicker rings feel heavier and may need a bigger size for comfort. Designs called “comfort fit” add extra metal inside the band, making the ring smoother against your skin. Both white gold and platinum can be made with comfort fit styles.

A ring’s size and shape affect how it feels every day. Shallow bands feel lighter and less bulky, but they may not last as long. Wider bands can feel tight, so you might need to go up a size. You can use online tools to compare the weight of white gold and platinum rings before you buy.

注記: Try on both metals to see which feels best for you. Think about your daily routine and how much weight you want to carry on your hand.

You have learned that white gold and platinum are not the same. They are made of different elements. They also look different and need different care. Platinum is heavier than white gold. It lasts longer and keeps its color for many years. White gold costs less money. It is good for many jewelry styles. The table below shows that platinum watches can cost much more than gold ones. Sometimes, platinum watches cost up to 82% more. This happens even though gold costs more per ounce. Platinum is rare and takes longer to make into jewelry. This makes it more valuable

Pick platinum if you want something rare and strong. Choose white gold if you want a lighter ring that costs less but still looks nice.
