Buyers have been advised to keep "the four Cs" in mind when they look for diamond jewellery, according to a source.
According to the Indian Economic Times, at this time of year there is an increase in consumers purchasing jewellery, but diamond goods are less straightforward to buy than items such as gold.
Because of this, consumers must remember the four Cs - clarity, cut, colour and carat, the news provider states.
The source also puts forward several other issues to consider when shopping for items such as gold diamond rings and oval-cut diamond rings, including the buy-back value.
With a solid buy-back value a consumer can enjoy a fair price should they need to sell or exchange the piece in the future.
The source states many well-known firms offer a large percentage of the diamond's value when it is exchanged for another piece of jewellery.
Recently, it was claimed by the JCK-Harrison Group the sale of diamonds online has increased by 39 per cent in the last nine years.
