First there was 'manscara', 'guyliner' and more recently, the launch of the first set of 'guylashes' but now it seems metrosexual men are trying to muscle in on another female aesthetic - 'mangagement' rings.

According to jewellery experts, there is a growing trend in men wearing engagement rings as they happily adopt the same public 'pre-commitment' signs women make when wearing a diamond ring on their left hand.

"Men and women both wear engagement rings in a lot of countries around the world. Engagement rings for men are a new concept in the United States," says Amanda Gizzi from the Jewelry Information Center.

While some men may think that them wearing a diamond ring is a metrosexual step too far and is best left to the ladies, jewellery trend experts claim that it's not necessarily about the size of the diamond, but the meaning behind it that appeals to men more.

"The idea that the man will also wear an engagement ring gives relationships a new sense of equality. It is a pre-commitment, commitment from both the man and woman," says Gizzi.

Experts also believe that the rise in 'mangagement' rings signal a new-found equality among men and allow men to show the world that they're 'off the market'.

Although engagement rings for men sound foreign to many, it's nothing new in countries like Brazil and Argentina, where the groom-to-be wears his 'mangagement' ring with pride.
