How to Find the Value of 1/10th 10K Gold – and Other “Fractional Gold Plated” Jewelry Pieces




Fractional Gold-Plated Marking – 1/10th 10k

It doesn’t take much looking through old trinkets like jewelry, pins, cuff-links, even vintage pen and pencil sets, before running across this somewhat confusing gold marking… 1/10th 10K.

Now the markings you’ve seen might not match that exactly, maybe you’ve seen something that said 1/10th 14K, 1/20th 12K, or even the super-confusing, “14K/20” and the like.

All of these markings are in the same category of gold jewelry marks and so we can automatically assume the following:

  • The piece that is marked is gold-plated, NOT solid gold
  • These markings always contain two parts, a FRACTION, and a GOLD KARAT PURITY
  • The FRACTION refers to the AMOUNT OF GOLD USED TO PLATE THE ITEM, in relation to the OVERALL WEIGHT OF THE ITEM
  • The KARAT PURITY is an indication of the gold content in the gold used

Examples:
Say you have a gold-plated tie tack marked “1/10th 10K”, all this really means is that “one-tenth of the total weight IS 10 Karat Gold!”.

On a watch case marked “1/20th 12K”… 1/20th of the weight of the watch case is equal to the amount of 12k gold used to plate the watch case (and thus, the amount of gold it originally contained).

Markings like “14K/20” seem confusing, but this is just another form of the fractional marking “1/20th 14K”.  These “compressed fractional markings” are often found on pieces that have minimal space for any marks at all.

 

Now that we’ve got some killer knowledge out of the way — we can put all the mumbo-jumbo above together and have the educational foundation to find the value of ANY Fractional Gold-Plated item we come across.

 

Here’s How to Find the Value of Fractional Gold-Plated Items:

Step 1:
Figure out HOW MUCH GOLD the item contains AND the GOLD PURITY.

Step 2:
Find the Current Gold Price for that specific GOLD PURITY.

Step 3:
Multiply the CURRENT GOLD PRICE (Step 2) with the GOLD CONTENT (Step 1).

In-Depth:

Step 1:
The GOLD CONTENT of the item is equal to the fraction marking MULTIPLIED BY the TOTAL WEIGHT of the item.
Example: If a gold-plated pin is marked “1/10th 10k” and the pin weighs 3.1 Grams, the GOLD CONTENT is 1/10th of 3.1 Grams or 0.31 Grams (of 10k Gold).

Step 2:
Use the Current Gold Price Calculator at GoldJewelryPrices.com to quickly find out the current melt value of a specific gold karat purity.  Find the value of 1 GRAM of whatever purity is marked on the item.
Example: If the item is marked “1/10th 10k”, use the calculator linked above to find the current value for 1 GRAM of 10K Gold.

NOTE: Gold Price and Gold Weight should be designated in the same weight unit.  I normally stick with GRAMS when weighing and valuing gold jewelry since it is easy and straightforward.

Step 3:
MATH, YAY!  Ok, this is easy… take the GOLD CONTENT from Step 1 and MULTIPLY it by the GOLD VALUE from Step 2.
Example: As I write this, 1 GRAM of 10K Gold is worth $16.18.  If we have 0.31 Grams of 10K Gold (Step 1) and 10K Gold is worth $16.18 per gram (Step 2), we have:

0.31 Grams of 10K Gold  x  $16.18 per Gram  = ~ $5.02 Gold Value

 

Here’s another quick example…

Say you’ve got a pocket watch case.  It’s marked “1/20th 14k” and weighs 35.8 Grams.

Step 1:
Gold Content = 1/20th of 35.8 Grams  =  35.8 / 20  =  1.79 Grams

Step 2:
14K Gold Value (per the calculator at GoldJewelryPrices.com): $22.64 per Gram

Step 3:
1.79 Grams x $22.64 per Gram  =~  $40.53

 

Who knew there could be SO MUCH GOLD in a pocket watch case!  Now you can see the beauty and power of knowing how to calculate the gold value in fractional-plated items.  You also know why I’ve spent so much time explaining the finer details… This is a very powerful and PROFITABLE tool to have in your gold scrapping arsenal.

So now you can figure out the gold value in all sorts of gold-plated items.  I hope this opens up a new world of possibilities for you.  🙂

Happy Hunting!

 




How to Calculate the Weight of Gold Jewelry Without a Scale




I could have easily titled this post “What Does a Gram of Gold Jewelry Look Like” since we’re going to cover pictures of gold jewelry along with their weights. But I’ll keep the title anyway.

What do you do when you need to know how much a piece of gold jewelry weighs but don’t have a scale to find the weight? Judging the weight of gold is a bit of an art form and can take time and practice to master. But once you’ve got it down, it is an invaluable tool when both buying and selling gold jewelry.

There are two main reasons why it’s a good idea to quickly and accurately estimate the weight of gold jewelry.

The first reason is when you’re selling gold jewelry and don’t have a scale to verify the weight… You want to make sure whoever you’re selling to isn’t trying to line their pockets by pulling a fast one on you. So if you can estimate the weight of your gold jewelry, you can just as easily estimate the value (and thus, a price range to expect when selling your gold). This is one reason GoldJewelryPrices.com was set up in the first place. Our free online calculator allows you to quickly and easily calculate the current market value of your gold jewelry.

The second reason to learn how to accurately estimate the weight of gold jewelry is when you’re buying gold. Being able to estimate the weight allows you to determine the market value of the physical gold contained in the jewelry. Keep in mind that other factors are involved (such as detail and workmanship) but knowing the gold value of your jewelry is a good starting point.

So… What does a gram of gold jewelry look like?

Since gold is such a heavy metal, it may be surprising how little of it is needed to equal a gram in weight. On the other hand, gold is malleable as well, which means it is easy to bend, stretch, and form the gold. This can make for extremely thin pieces of gold jewelry that don’t weigh as much as you might think at first glance. But again, the thicker pieces of gold jewelry can weigh much more as you might expect.

To put this into perspective, I’ve taken several pictures of different pieces of gold jewelry to help give you an idea of how much a piece of gold might weigh. This is the way to calculate the weight of gold jewelry without a scale… You’ve pretty much got to guess! Of course, the guessing gets easier and your guesses will be more accurate with time and practice (and looking at how much lots of different gold pieces weigh).

Besides the thickness of the gold, another thing to keep in mind here is the purity of the gold jewelry. Pure gold is much more dense and heavier than say, 14k gold, since gold is heavier than the alloys used to “dilute” pure gold into 14k gold. To keep it simple, remember – The higher the karat weight (purity), the less gold it will take to equal 1 gram. Example: 1 gram of 22k gold will be smaller in size than 1 gram of 10k gold.

Enough mumbo jumbo, let’s get on to the pictures of gold jewelry…

Take a look at the two 10k gold pendants in the picture below. Which one do you think weighs more? (To get an idea of scale, each piece of jewelry is approximately 1/2” wide)

Did you say the gold graduation pendant is heavier than the angel pendant? If you did, congrats… You’ve got a keen eye for gold! While the gold angel pendant may look bigger than the graduation pendant, the graduation pendant is thicker and actually weighs more. This is a good example of how gold can be formed to create thin jewelry that appears to contain more gold than it actually does. Let’s take a look at what each of these gold pendants weigh…

Together, they weigh just over 1 gram, with the graduation pendant weighing about 0.2 grams more than the angel pendant.

Let’s look at another example. This time we’ll use a 14k gold bracelet. The bracelet in the picture below is approximately 7” long and 1/16” wide. Can you guess how much it weighs?

While this bracelet is very thin and dainty, it may surprise you to find that it weighs just over 1 gram. Yup! Someone with enough time and the proper equipment could melt this bracelet down and make both the graduation and angel pendant pictured above. (They’d probably end up with a small amount of gold left over as well, since turning 14k gold into 10k gold would mean less gold metal and more alloy metals)

Here’s a picture of the gold bracelet’s weight:

And finally, we’ve got one last example showing what a gram of (nearly) pure gold looks like…

1 Gram of (almost) Pure Gold Nuggets

These are (almost laughably) tiny gold nuggets, probably between 22k-24k pure gold. It’s amazing how it doesn’t take much to equal a gram of gold.

So now you’ve hopefully got an idea of what to look for when estimating the weight of your gold jewelry. I used a target weight of 1 gram in the pictures since that is a good unit to mentally increase when estimating weights of larger pieces of gold.

I know this article doesn’t make you an expert, but hopefully it gives you a good starting point and basis when determining the weight (and value!) of your gold jewelry. Thanks for reading!
