When you inherit fine jewelry or inherit an entire estate, determining the actual market value of those items can feel overwhelming. Many people look for clarity online by asking, "How do jewelry appraisals work near me?" or "How do I safely sell inherited jewelry?"

To get the highest return and ensure a secure transaction, it helps to understand exactly what happens behind the counter. Professional estate jewelry evaluations rely on a transparent, multi-step process that combines physical material testing, weight verification against live market spot prices, and an assessment of designer or numismatic premiums.

Here is exactly what you can expect during a professional estate Jewelry Appraised in Keller, TX, at Keller Gold and Silver on Main Street.


1. Visual Inspection and Hallmark Verification

The very first step an appraiser takes is looking at the item under a jeweler’s loupe (a small, powerful magnifying glass) or a digital microscope.

  • Identifying Hallmarks: The appraiser looks for stamps that indicate the metal's purity (such as 10K, 14K, 18K, or 925 for sterling silver).

  • Checking for Maker’s Marks: Trademarks or designer signatures (like Tiffany & Co., Cartier, or David Yurman) are identified immediately, as these can add significant historic or brand premiums above the raw metal value.

  • Assessing Wear and Condition: The physical state of the piece is evaluated—checking for broken prongs, missing stones, or deep scratches that might affect its resale value.


2. Purity Testing: Acid vs. XRF Technology

Unmarked pieces or vintage estate items require precise testing to verify their exact precious metal content. Professional buyers use two primary methods:

  • Acid/Touchstone Testing: This traditional method involves gently rubbing the item against a testing stone to leave a tiny streak of metal, then applying a safe acid solution to observe the reaction. This verifies the exact karat weight without damaging the piece.

  • XRF (X-Ray Fluorescence) Analysis: For high-value items, advanced shops use non-destructive XRF scanners. This technology sends an X-ray beam through the metal to provide an instantaneous, down-to-the-decimal breakdown of its elemental composition (e.g., exactly 58.3% gold for 14K).


3. Weight Verification on Certified Scales

Precious metals are bought and sold by weight, specifically using the Troy ounce system (where 1 Troy ounce equals 31.1 grams).

  • Legal-for-Trade Scales: An authentic evaluation is always conducted in full view of the customer using high-precision, state-certified scales.

  • Pennyweights vs. Grams: Your jewelry may be weighed in grams or pennyweights (DWT). A transparent appraiser will always show you the exact conversion so you know precisely how much raw material you have.


4. Evaluating Diamonds and Precious Gemstones

If your estate jewelry contains diamonds, sapphires, rubies, or emeralds, these are evaluated separately from the metal weight.

  • The 4 Cs: Diamonds are assessed based on their Carat weight, Cut, Color, and Clarity.

  • GIA Standards: Appraisers look for laser inscriptions on the girdle of larger diamonds that match grading reports from the Gemological Institute of America (GIA).

  • Estate Premium: Unlike scrap gold buyers who only pay for the metal, a dedicated estate buyer evaluates whether the gemstones can be preserved, adding extra value to your final offer.


5. Calculation Based on Live Market Spot Prices

Once the purity, weight, and gemstone values are locked in, the final evaluation is tied directly to the global commodities markets.

  • Live Spot Prices: Gold, silver, and platinum prices fluctuate constantly throughout the day. A reputable local buyer monitors these live feeds in real time.

  • The Payout Percentage: The final cash offer is calculated as a mathematically transparent percentage of that day’s live spot price, factoring in the cost of refining if the piece is being sold as scrap, or the intrinsic resale value if it is being kept intact as fine estate jewelry.

💡 Quick Tip for Tarrant County Residents:If you are bringing in inherited items, do not clean them beforehand. Vintage pieces often carry a natural patina or historical finish that collectors actively look for. Cleaning an antique item with the wrong chemicals can inadvertently lower its overall evaluation.

Whether you have a single diamond ring or a large collection of family heirlooms, we believe the process should be completely transparent, educational, and pressure-free.
