Is It Possible to Test Gold on Jewelry with Stones?

ガイド 832 表示モード

Rings, necklaces, and bracelets are rarely just pure 金; they are often embedded with diamonds, emeralds, sapphires, or other stones. The good news is that it is absolutely possible to test gold in jewelry without removing the stones, as long as the right testing method is used. Modern, non-destructive testing technologies such as 蛍光X線 (蛍光X線分析計) allow professionals to determine the purity of gold in mounted jewelry accurately, safely, and without causing damage to the stones.

5D Hard Gold Overview

Why Conventional Methods Struggle with Stone-Set Jewelry

Traditional gold testing methods, like acid tests or fire assays, are not ideal when gemstones are involved:

  • Acid testing requires scratching or exposing a small part of the metal, which risks damaging the jewelry and does not give precise results when stones cover parts of the surface.
  • Fire assay is highly accurate but destructive, meaning the jewelry cannot remain intact after testing. Clearly, this is unacceptable for valuable gemstone jewelry.
  • Touchstone tests are simple but imprecise, especially if stones prevent consistent contact with the metal.

These limitations created a demand for a solution that can accurately test gold purity in jewelry with stones without damage—and this is where XRF technology excels.

How XRF Technology Solves the Problem

蛍光X線分析計 (蛍光X線) works by directing X-rays onto the surface of the jewelry. The gold atoms in the sample emit a unique signal that the analyzer interprets into an accurate purity reading. Because this process is 非破壊的, the jewelry does not need to be dismantled, and stones remain unharmed.

Advantages for testing stone-set jewelry include:

  • No Need to Remove Stones: The device analyzes exposed areas of gold without requiring stone removal.
  • 高速の結果: Readings are available within seconds, making it ideal for retail stores and pawn shops.
  • Accurate Purity Measurement: Detects differences in karats (例えば。, 14K, 18K, 24K).
  • Safe for Jewelry: No scratching, no chemicals, and no damage to stones.

For jewelers handling gemstone jewelry, this is the most professional, customer-trusted method.

Real-World Scenarios Where This Matters

  • 宝石店: When customers bring in rings with diamonds, staff can test the gold content directly without tampering with the stone settings.
  • 質屋 & Recycling: インスタント, non-destructive testing builds trust with clients and protects high-value items.
  • メーカー & 品質管理: Factories producing gold jewelry with stones need to ensure purity standards without damaging their products.
  • Refiners: While final refining uses destructive tests, XRF is invaluable for initial sorting and verification.
