Diamond Price

What is the right price for a diamond ring?

The key factor in the cost of your engagement ring is the diamond. There are 4 main components to pricing a diamond and a small change in one can have a significant affect on the cost. It is therefore important to know what these different characteristics are, as one may be more important to you than another.

What are the 4c's that affect the cost of your diamond?

  • First, is the weight of a diamond, which is measured in carats. (The bigger the stone, the more rare it is, therefore more expensive).
  • Second, is how perfectly the diamond was cut which determines how well it sparkles!
  • Third, is how clear and colourless  the diamond is. Diamonds that are tainted are much less valuable than perfectly clear ones.
  • Fourth is clarity which refers to how many imperfections there are in a stone.  Diamonds are natural and therefore never perfect and most imperfections that would be carefully noted and graded by a gemmologist using a 10x magnifying loupe are invisible to the naked eye.

You can also change the size and quality of your diamond at any time.  

Budgeting For Your Diamond Engagement Ring

The popular guide when purchasing a diamond engagement ring is to spend approximately two - three months' salary. More practically, though, you should not spend more than you can comfortably afford especially in tighter financial times it is absolutely fine to be more conservative.

Diamond Price - External Forces

Diamond prices are partly affected by natural forces: Formed over millions of years by extreme heat and pressure, diamonds reflect the beauty and miracle of nature. Mining them is an expensive process, and the large majority of mined diamonds are suitable only for industrial purposes. This leaves a small percentage of gem-grade diamonds to be cut and fashioned into jewellery, and this rarity is a key factor in why a diamond is so valuable.

Price is also affected by human influence: Economies of supply and demand impact on market prices, and the ever important factors of Cut quality and Carat Weight, as determined during the cutting process, also help determine the price a diamond can command.
