Valuing gold jewellery with diamonds and gemstones
The value of gold jewellery with diamonds depends on gold weight and fineness, gemstone quality and authenticity, craftsmanship, brand and market demand. A professional examination supports a documented valuation in a written report.
Determining a fair price for branded diamond and gemstone jewellery involves several factors. The most important are considered together.
Factors affecting value
- Gold weight and fineness: 24K gold is pure, while common alloys such as 18K contain 75% gold and 25% other metals.
- Market fluctuations: gold prices change with global supply and demand.
- Design and craftsmanship: workmanship and gemstone quality influence value.
- Local demand: regional market conditions also matter.
- Brand and designer: historical significance or a recognised maker can contribute to value.
