Diamond Necklaces

Sell Diamond Necklaces

You’ve probably seen celebrities adorned with diamond necklaces at exclusive events or affluent women wearing them at fancy parties (in the movies, or in real life if you’ve been lucky enough to get an invite). Diamond necklaces are definitely a show of wealth and can come in a wide variety of beautiful designs. When it comes to buying these, we take great care in providing accurate quotes based on not only the gemstones, but the metals as well.

While most diamond necklaces don’t rival the value of Rose’s blue diamond now sitting on the ocean floor, they can still be exceptionally valuable. And whatever the reason you have for selling, it’s a great way to get some extra cash for something collecting dust in a drawer.

The price we pay for diamond necklaces depends on a number of factors. First and foremost, the value of the diamond(s). When it comes to diamond necklaces, it’s often more common for there to be multiple diamonds and gemstones in them compared to smaller, simpler jewelry like rings or earrings. So it’s important that each diamond be evaluated. For more information on valuing diamonds, check out Diamond Karma’s article on how Diamonds are priced using the 4 C’s (the size of the diamond, the cut, the clarity, and the color).
The quoting process can be done much quicker and with more confidence if your necklaces contain certified diamonds. Certificates like AGS, EGL, GIA (the most popular), HRD, or IGI provide verified information about the 4 C’s, allowing for much quicker estimates rather than having to inspect the diamond.
If you have no documentation, it is still possible for us to buy your diamonds. Once it is sent to our facility, your diamonds will be inspected and appraised by a professional as part of the process in making an offer for your necklaces and other jewelry.

We do not purchase diamonds that:

  • Have been clarity enhanced
  • Have been color treated
  • Have been laser drilled
  • Have clarity of I1, I2, I3, or SI3
  • Have strong fluorescence
  • Have poor cuts

If your necklaces have other precious metals or gemstones in them, such as silver or diamonds, our team of professionals will estimate the price of each section and pay you appropriately for each one. We’ll clearly explain how your diamonds and jewelry are priced and give you a no-obligation offer to purchase your jewelry.

The accurate value of your diamond necklace can only be determined after it has been expected by a professional to verify its quality, weight, and purity.

Calculating the Value of Diamond Necklaces

The actual value of your diamond necklaces are determined by adding the value of the non-diamond component with the value of any diamonds or gemstones. Which makes sense, of course. We’re generally purchasing your unwanted diamond jewelry for its parts, rather than for the piece as a whole. In some rare cases, we are able to offer a price above just the value of the gold and diamonds, like if there is a premium brand name attached to the piece.

As mentioned previously, diamond necklaces often contain many pieces, so you’ll receive a quote that reflects a valuation of each piece.

Diamond Karma’s diamond value calculator is a good place to start if you’d like a rough valuation of your diamond (assuming you have a certification or are confident in the grading of each of the 4 C’s). But as mentioned above, the 4 C’s essentially determine the value of the diamond itself. Generally speaking, most of the value of the necklace is due to the diamonds.


Clarity refers to the presence of internal flaws (inclusions) and external blemishes in a diamond. Diamonds are graded on a scale ranging from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and/or blemishes visible to the naked eye). Diamonds with fewer inclusions and blemishes are more valuable.

If there are NO inclusions, that’s a sign that the diamond is lab grown. While lab grown diamonds look amazing and can be a good ethical choice, it unfortunately significantly reduces their resale value. At Cash for Gold Mailer, we rarely buy lab-grown diamonds.

Carats (Weight)

Carat is a unit of measurement for diamonds. One carat is equivalent to 200 milligrams. Larger diamonds generally command higher prices, but other factors such as cut, color, and clarity also play a significant role in determining the overall value.


The color grade of a diamond is a measure of how colorless or “white” it is. The GIA grades diamonds on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the more valuable it is considered to be.


The cut of a diamond refers to how well the diamond has been shaped and faceted. It is not about the shape (round, princess, etc.) but rather the quality of the cut, which influences how well the diamond reflects light. A well-cut diamond will sparkle more, making it more valuable.

Evaluating the value of gold and other pieces

If you’d like to calculate the value of the gold, you’ll want to learn how to determine the amount of gold in your jewelry. The value of the gold in your necklaces depends on the price of gold, weight, and purity of the gold.

The calculation would be very similar if the diamond is primarily made out of another metal, such as platinum (more valuable) or silver (less valuable).
