Diamonds for engagement rings and other jewellery

Three of these are natural qualities that depend on the formation of the stone over many years and the final factor is how it is cut. The colour is probably the easiest thing to see with the naked eye, although minor variations can only be determined by a skilled jeweller. Generally speaking the whiter a stone is the more desirable it is. There are some coloured stones that are even rarer but for engagement rings white examples are traditionally used.The clarity of a diamond is the second quality on our list. This quality is determined by how few flaws a stone has. Since the discovery of large deposits of diamonds in South Africa over a century ago these gemstones are not anywhere near as rare as they once were. Given this, you might be forgiven for wondering why people are still prepared to pay quite large sums of money to acquire them and why they are so sought after. The ***st answer to these questions is that whilst in general there may be more stones being mined these days, not every stone is the same and good quality ones are still relatively rare.There are four main qualities that a diamond is judged on.
