March 02, 2020 - Jewelry & Luxury Items

Diamonds are forever, but gold can be sold.

Or at least melted down and made into something new. But who wants to waste time doing that when you can you can sell your old 18 karat gold jewelry?

With Spring in the air, it’s time to clean out your jewelry box and scrap that old, unworn gold for cash.

Of course, it’s important to figure out the prices of 18k gold before you hand over your old jewelry to your nearest pawn shop.

What Are the Prices of 18K Gold?

The first thing you’ll want to do is make sure your gold is real.

To do this, you can use a magnifying glass to read the karat number on each piece. If that number is no longer legible, you’ll want to have it tested by a reputable dealer. (This is also a good idea to ensure that your jewelry is not just gold-plated).

Once you are certain that you have 18 karat gold on your hands, you can take the next steps to figure out how much it’s all worth.

Step 1: Determine the Purity

Of course, the prices of 18k gold will differ from 24k gold because of its purity.

24k gold is 100% pure gold while anything below will be a gold and metal alloy. 18k gold is only 75% gold, therefore it will cost 75% of the stock price for pure gold.

A reliable gold buyer will only deduct up to a 15% margin of the current stock price. Using a gold calculator can help you determine your 18k gold ring value before you meet with a buyer.

Step 2: Determine the Weight

Pure gold is sold by the (troy) ounce while karat gold is sold by the gram.

One troy ounce equals 13.1 grams. However, it’s not as simple as dividing grams into ounces. Keeping in mind that your 18k gold is only 75% pure gold, the weight of your piece will have to be multiplied by .750.

The dollar amount will also vary depending on the spot price.

Step 3: Determine the Spot Price

Gold is in a state of perpetual flux. Its value rises and falls consistently throughout the day depending on supply and demand. Because of this, the value of your gold may be greater in the afternoon than it was in the morning.

To complete the formula for the per-gram value of your gold, you’ll need to determine its market, or spot price. All you have to do is check the internet for updates and you will find the variable to the formula.

Step 4: Calculate the Formula

Here’s what you have to do to figure out the price of your 18k gold:

  • Divide the spot price by the gram (13.1)
  • Multiply by the purity (since 18k is 75% pure gold, you would multiply .750 by the number of dollars per grams)

Keep in mind that gold must go through an assaying process to determine its actual purity. This requires melting and separating a sample of the gold to weigh it once more to determine its melting price.

Are You Thinking About Selling Your 18k Gold Pieces?

Now that you know how to calculate the prices of 18k gold you can sell your old jewelry with the confidence that you will be getting the best price.

The first step if finding a reliable buyer in your area, and we can help you with that.
