To determine the value of your antique diamond jewelry, consider these key steps:

1. Identify the Era and Style: Knowing the period (e.g., Victorian, Art Deco) helps determine historical and aesthetic value.
2. Evaluate Diamond Quality: Assess the cut, color, clarity, and carat; older cuts like Old Mine can add uniqueness.
3. Check hallmarks and maker’s marks: marks of origin or notable makers (like Tiffany & Co.) can significantly increase value.
4. Consult a Professional Appraiser: An expert appraisal ensures an accurate valuation and provides formal documentation.
5. Compare Market Prices: Check recent auction sales or dealer listings for similar pieces to gauge current market demand.

These steps will help you establish a reliable estimate of your jewelry’s worth.
