The research, which was conducted by Vashi Dominguez, founder of the jewellery brand Vashi.com, has revealed that the typical value of a woman’s jewellery increases by 2,000 pounds every 10 years as they reach middle age.
By the time she reaches 50, her jewellery is worth 8,000 pounds, reports femalefirst.co.uk.
The collection generally includes up to 150 pieces with the most expensive item normally an engagement ring worth 3,000 pounds.
The study also shows that only 33 percent of the jewellery is regularly worn. The remaining two-thirds are left neglected in a jewellery box because just nine percent of women sell or remodel unwanted pieces.
“Many women don’t realize their jewellery box is such a valuable treasure trove. These findings prove the continual popularity of jewellery. No matter her age, women love the feeling new jewellery gives them,” said Dominguez.
“They are consistently adding to their collections through their 30s and 40s. Women see fine jewellery as an investment they can enjoy for life. Many affluent 50-year-olds are sitting on jewellery collections worth more than 40,000 pounds – far more than the average annual wage,” added Dominguez.
