Throughout this process, the appraiser documents all findings and observations. This documentation forms the basis of the final appraisal report.

4. Valuation Calculation

With the purity and weight determined, the appraiser calculates the item’s base value using current market rates for gold. This calculation typically follows these steps:

1. Convert the item’s weight to troy ounces if necessary.
2. Determine the gold content based on karat purity.
3. Multiply the pure gold weight by the current market price per troy ounce.

For example, a 14-karat gold ring weighing 10 grams:
– 14 karat = 58.3% pure gold
– 10 grams x 0.583 = 5.83 grams of pure gold
– 5.83 grams ÷ 31.1 (grams per troy ounce) = 0.1875 troy ounces
– 0.1875 troy ounces x current gold price = base value

However, the final valuation isn’t just about the gold content. The appraiser considers additional factors that can affect the item’s worth:
– Craftsmanship: High-quality or intricate work increases value
– Brand: Items from prestigious makers command higher prices
– Rarity: Uncommon or historical pieces may have added value
– Condition: Well-preserved items are generally more valuable

The appraiser uses their expertise to adjust the base value, accounting for these factors.

5. Appraisal Report Creation

The final step is compiling all the gathered information into a detailed appraisal report. This document serves as an official record of the item’s value and characteristics.

A comprehensive appraisal report typically includes:
– Detailed description of the item
– Photographs documenting the item’s appearance and any unique features
– Results of all tests performed (purity, weight, etc.)
