Gold: Preciously Classic

Being number 79 on the periodic table with Au being it’s chemical compound, gold is the one precious metal that is the most widely used across the world for thousands of years. It has been used as currency, making decorations like statues, and has even been the basis of many legends. Something about the soft, shiny yellow metal almost seems to cast a spell over people, making them go to the ends of the earth to find it.

 

Yellow & White Gold

All gold naturally comes in the yellow form everybody is familiar with. Yellow gold is used for various things, including jewelry, art, and even electronics. Gold is actually one of the best conductors of electricity, which is why it is used on circuit boards, and adapters. Gold in its purest form (24 karats) is soft and easily malleable, which is why alloys are generally added to it to make it harder. This is what is done to create White Gold.

 

White Gold is mainly used for jewelry, and is something some people prefer over silver or platinum. The reason for this may be because silver requires special care to keep it in good condition, and platinum can be expensive. White gold is created by adding one or more different metals to it which include nickel, manganese, and even platinum. All white gold jewelry contains rhodium plating, which is what gives the white gold its silver appearance. Without it, the metal would be dull and off in color, looking almost tarnished.

 

Karats

If you are new to the jewelry world, there may be some terminology you are not familiar with, such as the term “Karats”. Now, don’t mix this up with “carats”, which is the unit of measurement that determines a diamond or gemstone’s weight value. With gold, the term “Karats” refers to the metal’s purity. It is measured on a scale that goes up to 24 parts, and goes down in increments of six.

 

  • 24 karats- This is the purest form of gold. In this state, there are no alloys added to the metal, which leaves it rather soft.

  • 18 karats- This is the second highest purity, and means that are 18 parts gold to 6 parts alloy metals. This is usually the ideal form for high quality jewelry.

  • 14 karats- The most common type of gold used for jewelry, it has 14 parts gold to 10 parts alloy metals.

  • 10 karats- This is the minimum standard in the U.S. for jewelry to be labeled “Gold”, and has 10 parts gold to 14 parts alloy metals.

Pure –

 You want everything to be exceptional when you propose, and nothing is more exceptional or perfect than presenting a PURE platinum engagement ring.

At 90-95% pure platinum, you are getting more of the precious metal that you are paying for.

Platinum jewelry’s purity makes it naturally hypoallergenic, which is ideal for people with sensitive skin or allergies.

The other 5-10% of the metal content in platinum jewelry is usually other precious metals. White gold jewelry is often alloyed with base metals, such as nickel, which can cause allergic reactions.

Platinum jewelry’s purity means it will always remain white.

 

Look for the Platinum Assurance Stamp Inside the Ring

The stamp inside the ring should have markings that denote platinum jewelry, which are: Platinum, Plat,Pt followed by the level of purity, i.e. Pt900 or Pt950. The number 900 denotes 90% pure platinum, and 950 denotes 95% pure platinum. There is no difference in quality between 90% and 95% platinum.

Rare-

Platinum is like true love, is precious and RARE.

Platinum is 30 times more rare than gold. Approximately eighty-eight tons of platinum

are made into jewelry per year, compared to 2700 tons of gold.

Because of its non-corrosive nature and strength, platinum is in high demand in industries other than jewelry.

Over 70% of the platinum mined goes to other industries, for items such as life-saving pacemakers, pollution-controlling catalytic converters, computers and flat screens.

Like all rare things, platinum is valuable, and will hold its value over time.

If all the platinum ever mined were melted and poured into an Olympic-sized pool, the platinum would barely reach your ankles. Gold, however, would fill three pools.



 

Enduring –

 

As the ultimate symbols of love and commitment, a platinum engagement ring and wedding bands are perfect for a LIFETIME of everyday wear. And like your love, platinum grows stronger over time.

 Besides giving platinum its distinctive weight, its density makes platinum highly durable, so platinum jewelry can be cherished for generations.

 All precious metals age with daily wear. Over time, platinum develops a rich finish, called a patina, but it doesn’t wear away. You will rarely need to redshank or reinforce a platinum ring. In fact, as the metal is worked by wear, the surface area actually gets harder.

 All precious metals scratch. However, due to its density, when platinum is scratched the metal is merely displaced, and very little metal is lost. Gold loses slivers of metal with every scratch.

 

 

 

Feels Significant –

Platinum’s high density is the reason for it’s DISTINCTIVE WEIGHT, durability and strength. It not only looks beautiful, you can feel it is of the finest quality.

One of the densest of precious metals, platinum is 60% heavier than 14K gold and 40% heavier than 18K gold.

Compared to other metals, platinum jewelry feels distinctly different when you hold it in your hand.  A six-inch cube of platinum weighs 165 pounds.

 

 

 

Emotional –

You can feel self-assured knowing platinum is the VERY BEST metal for the three rings that must be perfect in every way.

81% of women said they preferred platinum for their engagement ring*. You can be confident that platinum is most likely her first choice.

Platinum is the most befitting metal to symbolize the ultimate commitment between two people. The legacy of platinum as the choice metal for marriage is evidenced by the antique and heirloom bridal jewelry we see today. Begin your own lasting tradition in platinum.

Platinum loses little metal to scratching or everyday wear, ensuring that your platinum jewelry will endure for a lifetime.

There is an innate sense of pride in giving, wearing and owning platinum.

Real White –

Only the natural, unchanging REAL WHITE color of platinum is worthy of the wedding rings that will symbolize your life long commitment to each other.

Platinum is a pure, real white precious metal. Conversely, white gold is actually yellow gold that has been whitened and rhodium plated.

Because it is a naturally white metal, platinum will not change color or fade. It requires no maintenance to stay white, unlike white gold.

The optimal setting for diamonds is platinum, a naturally white metal that won’t ever reflect color into the diamond. Platinum enhances the brilliance of diamonds and other gemstones.

 

 

Secure –

 Her engagement ring will be one of the most meaningful pieces of jewelry you will give her and the most important diamond. Platinum will hold the diamond most beautifully and SECURELY, providing piece of mind.

Platinum’s strength, durability and corrosion resistance make it the most secure setting for diamonds and other precious gemstones.

A platinum prong offers better protection for diamonds than the more brittle gold prong, which may break when subjected to force.

When properly designed, even with the smallest, most delicate of prongs, platinum’s strength is unsurpassed in securing precious gemstones.


 

Metal Comparison –

 Platinum and white gold are two very different metals. The biggest differences between platinum and white gold are that platinum is a naturally white metal, and is more dense and durable.

The difference in cost is primarily due to platinum’s rarity and higher level of purity in platinum jewelry. When comparing costs, keep in mind the maintenance required for white gold over a lifetime, such as rhodium plating to keep it white and reshanking and retipping the prongs. Platinum may be a higher investment initially, but its enduring nature makes it the best value in the long run.

 

 

Frequently Asked Questions –

I thought platinum was not supposed to scratch.”

There are often misconceptions about platinum because it is known as being the strongest and most durable precious metal. The fact is that all precious metals scratch. Platinum is one of the most durable of metals because it loses li

ttle metal with wear and displaces when scratched, as opposed to white gold, which loses a sliver of metal with every scratch.

 

Is platinum jewelry softer than white gold?”

Platinum jewelry’s softness/hardness is largely determined by alloy and manufacturing process. 950Pt/Ruthenium, for example, is 135 HV compared to 120-130 HV white gold. So it is inaccurate to make a blanket statement that platinum jewelry is softer than white gold. Keep in mind that hardness is not equated to strength and durability, only the resistance to scratching. Regardless of HV, the incomparable endurance of platinum gives it a wearable, heirloom quality.

 

Does platinum lose its shine?”

All precious metals eventually show wear, including platinum. However, the enduring nature of platinum sets it apart from other metals, as platinum loses very little

metal with wear and it maintains its volume. It is also platinum jewelry’s nature, especially rings, to develop a warm patina as it records a lifetime of wear and

memories on its surface. Proper cleaning and/or buffing keeps it looking beautiful as it ages.


 

Silver: Precious Elegance

 

This precious metal comes in at number 47 of the periodic table, and it’s chemical symbol is Ag. Silver has become rather trendy in today’s world, but it has been used by countless generations before us. Like gold, this metal, while in its purest form, is soft and easy to shape. That’s why silver is perfect for making jewelry and settings. It’s also a great conductor of electricity, much like gold, and is often used to solder circuit boards. Over the years, it’s been used as currency, and adding flare to decorations and clothing, and to make cutlery with. Today, it has a wide range of uses, including photography film, chemical compounds, and even disinfectants.

 

Sterling Silver

Sterling silver is sometimes mistaken as pure silver because of how it looks. However, sterling silver is actually an alloy that contains 92.5% pure silver, which is the standard amount for today, while the rest is other metals. The reason for this is because pure silver is too soft to make anything like cutlery and such. When you buy a piece that is labeled “Sterling Silver”, make sure to look the item over for a number stamped into it. That number should be 925, which indicates that the piece contains 92.5% silver. Like platinum, silver is graded on a scale of 1000 parts. So, let’s say a piece is stamped 575. That means that piece is 57.5% silver, and the rest of it is other metals. Keep that in mind when you go to buy. If it doesn't have 925 stamped on it, you will want to go somewhere else.
