The value of precious jewelry is determined by multiple interconnected factors including the rarity and quality of gemstones (such as color, clarity, and cut), the craftsmanship and materials of the setting, the historical period and design style, and the provenance or family history of the piece. For example, a Brazilian yellow diamond ring from around 1910 with a cushion-cut stone weighing 4-5 carats would be valued between £1,000-£15,000, while a Victorian cluster ring with rare colored diamonds could be worth £2,500-£5,000 or more.
