Selling Gold Jewelry — Understanding Purity & Alloys
Gold is valued not simply by its weight, but by its purity, or fineness, which is expressed in karats, (kt.) or carats (ct.) This seemingly simple metric can be more complicated than first thought, thanks in part to the fact that pure gold is extremely soft, and unsuitable for the manufacture of jewelry. As a result, pure gold is usually mixed, or alloyed, with other metals to make it more durable.
The most pure gold is 24 karat gold. All other gold will have a lesser karat value, and is in fact simply an alloy of gold and some other metal or metals. The karat value represents the ratio by weight of gold to the other metals. Since pure gold is 24 karats, all alloys are expressed as the parts gold per 24. For example, 18 parts gold out of a possible 24 is 18K gold — 75% pure, with 25% being other metals.
How to Identify Gold Jewelry
European gold markings are often expressed in decimals. A mark of 750 would indicate 18 karat gold, or 75% pure gold.
Other marks to look for on gold jewelry include EP (electroplated), GEP (gold electroplated), RGP (rolled gold plated), and HGE (heavy gold electroplate), indicating that a piece is rolled, filled, or plated with gold. It is important to note that just because a piece doesn’t have one of these marks doesn’t mean it is solid gold. For a piece without markings, you’ll may need to use a different method to determine the gold content.
Often you can tell if a piece is gold plated by close inspection. Discoloration, uneven coloring, or chipping can indicate that a piece is plated. If your jewelry discolors your skin, the gold is certainly fake.
An acid test is the most reliable gold test available at an affordable price.
Another way to determine if a piece of jewelry is solid gold is to perform a density test. You’ll need to accurately weigh your piece in grams, and immerse it in a graduated cylinder and read the number of millimeters of water it displaces. (The piece must be all gold, with no gemstones).
Pure gold has a density of 19.3 grams per millimeter, so dividing the mass of you piece by the number of millimeters of water it displaces will give you a good gauge of its density. The closer the number to 19.2, the more pure the gold.
Magnet testing can be used for jewelry, but is often inconclusive as lower purity solid gold can have magnetic properties, and plated metals are often non-magnetic.
None of this testing is, of course, necessary if you have gold jewelry from a well-established jewelry brand such as Cartier or Tiffany & Co.. If you would like sell gold jewelry online from a celebrated luxury jewelry, contact Diamond Estate now for an immediate cash offer for your items.

What a relief when we met with Carl to sell my gold.
I thought he was very straightforward and knowledgeable. He will weigh your gold items in front of you and for the items that he cannot read the stamp on he will test them. He even explained the testing process to us. He was very upfront and explained the steps he uses to calculate the prices he pays. Wow what a surprise, I thought I was going to get a lot less than what he actually paid. I definitely walked away feeling like I had been treated very fairly. – Michelle T.

Carl is knowledgeable, kind, and honest. It was a pleasure to have met him.
Visually piece by piece he inspected the jewelry and to both mine and Carl’s disbelief most of the pieces were not what the pawn shop said they were. The folders that supposedly contained 10kt were actually 14kt! Can you believe that? Carl is very knowledgeable, kind and honest. It was a pleasure to have met him, and I highly recommend stopping by to see him when you are looking to sell gold jewelry. Thank you Carl! – Jane C.

How to Sell Colored Gold Jewelry Online
Below you will find some more information about colored gold, so that you can obtain a better understanding of the precious metal in your gold rings, necklaces, bracelets, and earrings.
What is Colored Gold?
All gold is colored of course — we can all picture stacks of gold bricks in some mythical vault: a rich, lustrous golden hue reflecting a bright glint of light that meets the eye with a ubiquitous, “bling!” But not all gold is the pure gold of those iconic bricks. Since pure 24 carat gold is too soft to be used in jewelry, most of the gold we see on a daily basis is an alloy, or a mixture of gold with other metals. And while many of the metals used to strengthen gold are specifically chosen to preserve the color we all know and love, some alloy metals can produce different colors.
Sell White Gold Jewelry
White gold is a mixture of gold and a white metal, most commonly nickel, palladium, or manganese. It is available in a wide variety of hues, from pale yellow to tinted brown to pale rose-red. Often covered with a plating of rhodium for durability, white gold is probably the most popular ‘colored’ gold. It is commonly used in all kinds of jewelry, from rings and necklaces to pins and brooches.
The qualities of white gold vary depending on the metals used, with nickel producing a hard alloy suitable for pins and rings, and silver and palladium yielding a more malleable alloy, good for gemstone settings. Typical alloys used for making jewelry can include as much as 10% nickel, which can lead to allergic reactions for some, especially on rings when the rhodium plating grows thin.
Sell Rose Gold Jewelry
Also known as pink or red gold, rose gold is a gold and copper alloy. Its ‘redness’ is directly related to the copper content in the alloy — the more copper, the stronger the red color. Typical alloys are 75% gold, with the remaining 25% being copper (red gold) or copper and silver (rose and pink gold). Red gold was extremely popular in Russia in the early 1800s, and is recently experiencing a comeback in the 21st century, being commonly used for engagement rings and wedding bands.
Sell Green Gold Jewelry
Green gold is an alloy of silver and gold, once known in its naturally occurring state as “electrum.” The color of green gold is subtle — more a ‘yellow gold with a greenish tint’ — and is best highlighted against areas of yellow, white, or rose gold. Traditional green gold was made of 75% gold and 25% silver, though harder metals like nickel and zinc are now commonly added for strength. Cadmium can also be used to produce green alloys, but health concerns have greatly curtailed its use.
Sell Purple or Blue Gold Jewelry
Purple and blue gold result from intermetallic compounding rather than alloying, and their properties can be quite different from gold. Purple gold, (or amethyst gold), is a gold-aluminum intermetallic, and though nearly 80% gold, it is extremely brittle, and is often cast and faceted to be used as a “pseudo-gem” in jewelry.
Blue gold is an intermetallic compound of gold and indium, typically used only to surface plate gold or silver to attain a blue color. Black gold can be achieved by electroplating with black rhodium, or by patination using sulfur and oxygen compounds. These so-called ‘exotic’ gold colors remain rare, and are mainly used as highlights in multi-colored gold pieces.
