How Gold Is Tested: Understanding Karats and Value for Orange County Sellers
Selling gold can be straightforward if you understand how gold is tested and what your items are worth. For Orange County residents, knowing the difference between 10k, 14k, 18k, and 24k gold—and how certified testing works—is key to getting the highest payout when selling gold locally.
This guide explains gold karats, testing methods, and why professional evaluation matters.
Understanding Gold Karats
Karat measures the amount of pure gold in an item. The higher the karat, the more pure gold content, which directly affects cash value:
10k gold – 41.7% pure
14k gold – 58.5% pure
18k gold – 75% pure
24k gold – 100% pure
Knowing the karat helps you understand how offers are calculated and ensures you are not undervalued.
Why Testing Gold Is Crucial
Certified testing ensures you are paid fairly based on actual gold content, not appearance or weight alone. Professional buyers like Glitter Bug Gold Buyers use tools such as the ThermoFisher Niton™ Precious Metal Analyzer to provide accurate, non-destructive testing.
Benefits of professional testing:
Accurate valuation for all karats
Non-destructive and safe for jewelry
Transparent and immediate results
Prevents underpayment by unreliable buyers
Methods of Testing Gold
XRF Analysis (X-ray Fluorescence): Provides a detailed reading of metal composition without damaging the item.
Acid Testing: Determines karat by reaction to acids, often used as a secondary check.
Electronic Testing: Measures electrical conductivity to estimate gold content, usually for smaller items.
Professional buyers combine methods to ensure precise valuation.
How Testing Affects Your Payout
Gold valuation depends on:
Weight of the item in grams or ounces
Purity (karat) measured through certified testing
Current market spot price
Accurate testing ensures that your offer reflects real market value.
Avoiding Underpayment
Many inexperienced sellers are underpaid because buyers rely on visual inspection or non-certified methods. Watching a certified testing process in real time protects your investment and gives you confidence in the offer.
