Buying has been widely effected by Brexit and volatility in currencies. The Knight Frank Luxury Investment index Q4, 2017s states investment in jewelleries can provide growth of 4 per cent a year, and a 10-year investment can get up to 138 per cent growth. Art market research suggests the value of jewellery increases by more than 50 per cent in 10 years.
The best returns were offered by the Art Deco pieces, vintages and brands introduced during the First World war or the 1920s- 1930s. The time of Belle Epoque is recognized for its considerable values. These are the ones launched in the years from 1870s to the start of the First World War, where the precious platinum and diamond jewelleries or bracelets were popular, which were weightless and had lace settings.
The most sought after pieces from such generations grew in value by more than 90 per cent in the past decade. Another phase of jewellery mania was seen in years from 1930 to 1950, also known as the retro phase.
Most such jewelleries were worn for generations.
Identifying the designer items
Most people believe the designer pieces have some identification mark but the mark on the jewelleries of Arpels, Cartier and Cahenl are not easy to identify. The brand such as Cartier was found in 1874 and it holds great reputation due to higher demand with film stars, royalties and business tycoons. The client of the brand includes the Duchess of Windsor, Grace Kelly, Elizabeth Taylor and others. At the start of 20th century, it was producing bracelets with a set of specific colour and designer stones. In years from 1910 to 1940, the brand established itself as one of the leading global jewellery brands.
Since 1992, brands such as Christie started holding auctions. The auctions showcased objects, jewelleries and clocks. Most of the production of the brand took place in Paris. The pieces have a dog head mark for platinum and an eagle head for gold. Its pieces made in New York or London did not have a hallmark.
Jewelleries embedded with precious stones
Precious stone jewellery got famous in 1910, when Bonhams and Christie started producing it, and these were mostly made with rubies, sapphires, emeralds and diamonds.
Many different types of stones were discovered during this time, where the rarest ones were most expensive E.g. A blue-purple stone tanzanite was worth £1,000 a carat, and the stones such as jadeite and alexandrite could sell for more than £10,000 a carat.
Identifying the real pieces
It is difficult to estimate the real value of gemstones jewelleries at auctions, even if, these auctions provide certification of authenticity and other details because the price involves a number of factors. The stones properly cut and embedded in gold or platinum, or those combined with other rare stones, can sell for millions. The rare ones have higher prices.
In addition, sometimes, a popular brand offers discounts up to 50 per cent, giving an opportunity to buy such luxury pieces at a discounted rate.
