Understanding Gold Karat Values: 10K, 14K, 18K, and 24K Explained

When you look at gold jewelry, you'll often see stamps like "14K" or "18K." But what do these numbers actually mean? Understanding gold karats is essential whether you're buying, selling, or just curious about your jewelry.

What is a Karat?

A karat (K or kt) is a measurement of gold purity. It tells you how much of the metal is actually gold versus other alloys. The scale goes from 1 to 24, with 24 being pure gold.

Breaking Down the Karats

  • Very high purity
  • Rich yellow color

  • Common in Middle Eastern and South Asian jewelry

  • How to Identify Gold Karats

    Look for stamps on your jewelry:

  • Inside of rings
  • On clasps of necklaces and bracelets
  • On earring backs
  • Common stamps include:

  • 10K, 14K, 18K, 24K
  • 417 (10K), 585 (14K), 750 (18K), 999 (24K)
  • How Karats Affect Value

    Higher karat gold contains more pure gold, so it's worth more per gram. However, the total value depends on:

  • Weight of the piece
  • Current gold spot price
  • Any additional value (designer, antique, gemstones)
