In our latest Jewellery Market Update, we explore the impact of a continued strength in precious metal pricing and evolving consumer demand on valuations. Covering the evolving dynamic between natural and laboratory grown diamonds at retail and wholesale level, the impact of new High Jewellery collections on demand for antique jewels, and fascinating trends in coloured gemstones. In this ‘snapshot’ of industry news, we explore the impact of prices at retail level and subsequent valuations.
Precious Metal Prices
From January to June 2026, gold and silver bullion prices have increased 5%, appearing to plateau somewhat compared to peak increases seen in 2025, meanwhile platinum has seen a later increase of 45% in the last six months. Gold, mid-range designer jewellery such as Tiffany & Co HardWear, Bvlgari B.Zero.1 and Cartier Love collections have all seen back-to-back increases at retail level. Clients with pieces older than 2-3 years could be drastically underinsured.

Diamonds
The advent of laboratory grown diamonds has dampened natural diamond prices under 1 carat, particularly those less than 0.50 carat.
Natural diamonds to maintain a premium include those over 2 carats of desirable grades (D-I, F-VS), elongated fancy cuts, old European, old mine and cushion cut diamonds. Exclusive fancy cuts such as Boodles’ Ashoka cut and Louis Vuitton’s LV Monogram Star cuts remain buoyant.

Gemstones in ‘mid-tones,’ including lilac spinels and sapphires, grey spinels, mint green tourmaline are becoming incredibly popular and sought-after in contemporary jewellery, as well as pink topaz in antique jewellery rising in demand and value – see Christies’ 19th century pink topaz and diamond brooch, sold in June for £330,000 – over 7x its low estimate.
