How to value your jewelry

This is the first part of a series that we are publishing, dedicated to helping people find the true value of their treasured possessions. Our aim is to give you the information needed to help you figure out if you can value your own jewelry, or if you should submit it for a professional valuation.

Many people may have inherited a piece of jewelry from a loved relative, or perhaps have a wedding/engagement ring that is no longer needed… whatever the case may be, here are a few tips from our specialists on finding the value.

Before we begin, an important note on valuing jewelry is making sure expectations are set beforehand. Many people think they can recuperate the retail value of their jewelry. However, the value of fine jewelry depreciates as soon as it’s sold. A piece of jewelry is like a car; it can lose approximately 40% of it’s value as soon as it is “driven off the lot”.

Of course, this can differ greatly depending on the type of jewelry, and several important factors to keep in mind when trying to determine if your piece of jewelry is of value.

Look for hallmarks.

Hallmarks are typically used to describe the metal content of a piece. If there is more than one hallmark, it is usually used to call out either the designer, country of origin, or manufacturer. Unless your item is over 100 years old, or the hallmark has worn off, all fine jewelry should have some type of visible hallmark.

You can find these markings on:

    1. The inside of a ring or bracelet

    2. The post of an earring

    3. The clasp of a necklace

Common hallmarks to keep an eye out for:

    1. Gold hallmarks: 18K, 14K, 10K, 750, 585, 375

    2. Platinum hallmarks: 950, PLATINUM, PLAT

    3. Common silver hallmarks include 925, Silver, 800, Sterling

The list goes on and on. The good news is, that if your jewelry has any hallmark at all, it’s more likely than not that it is of some value. Keep your eyes peeled for hallmarks of value such as Cartier, Tiffany & Co, etc. These hallmarks indicate value. If your jewelry has marks such as Sarah Coventry, AVON, & Trifari, these are common costume jewelry marks (therefore they do not have a great deal of value at auction.)

If your item looks antique, get it professionally valued. If it looks new without hallmarks, it is most likely costume jewelry.

What does it weigh?

Items made of gold or platinum will weigh more than their fake counterparts. If you find yourself in the possession of a gold or platinum chain, look for factors like color as well. Wear and tear on fake chains will appear discolored/multi-colored. If the chain is made from real platinum or gold, the color stays consistent regardless of wear (this doesn’t apply to white gold, however.)

Inspect how it’s made.

High quality costume jewelry can be confused with fine jewelry. However one solid indicator of whether your jewelry is of value or not, are the prongs or other attachments. If you see any indicator that glue was used to mount the item together, this is one of the strongest indicators that your jewelry does not have value at auction.

Another good rule of thumb is to hold your gold up to a magnet. If it sticks, it’s fake!
