Diamonds are an increasingly attractive proposition to investors, it has been claimed.
Expert Bill Roy believes the jewels are interesting those looking for alternative markets in the current economic climate, reports stuff.co.nz.
Mr Roy states quality stones, such as those found in brilliant-cut diamond rings and diamond stud earrings, are in demand as owners can "wear them as they increase in value", the website claims.
He told the source: "We are only talking about the top 0.5 per cent of diamonds. These hold their value and increase over time."
The website claims diamond investment could be a long-term and safe choice for those looking for an alternative market, as the dollar continues to struggle.
Meanwhile, recent reports state diamond trading in Dubai is currently worth $3.03 billion (£1.70 billion), reports Gulf Daily News.
The newspaper claims this represents a 36 per cent growth in six-month figures when compared with last year.
