1. Untreated coloured gemstones
About 90 per cent of gemstones are heated to improve their colour or clarity. Some of the rarest untreated coloured gemstones are Kashmir sapphires, so it’s likely these will be very popular at auction this year.
2. Pink diamonds
Less than 0.1 per cent of diamonds mined worldwide are pink and they are only found in certain areas, such as the famous Argyle mines in Kimberley, Western Australia. Last year, the Argyle mines closed for good, and prices for pink diamonds reportedly shot up 40 per cent.
4. Jewellery Art
Collectors are more likely to wear their jewellery nowadays, rather than lock it up in a safe. So mixing and matching artistic jewellery with other fashion items is becoming increasingly popular.
5. Online purchases
Buying online for the first time can be exciting, but also nerve-racking. Always reach out to specialists and ask to see pictures and videos of pieces you’re interested in before placing your bid.
