Rubies rose by 47% over the same period.

Emeralds rose significantly in 2005, but between 2006 and 2013 only rose by about 6%.

According to the RapNet Diamond Index (RAPI), the price for one-carat diamonds has risen by 32% since 2006.

In other words, sapphires and rubies have outpaced diamonds over the past seven years.

Jaspreet Chawla, a London-based gemmologist, believes the price rises reflect a growing trend in certain markets.

"In the US and Germany there is a more pronounced move towards coloured stones," she says, "increasingly so after Kate Middleton wore a sapphire.

"But the UK is still diamond-dominated."

Celebrities may indeed be helping to make coloured gemstones fashionable.

Penelope Cruz and Elizabeth Hurley both have sapphire rings, while Halle Berry and Angelina Jolie are fans of emeralds.
