What 2 BIG Factors Affect 1ct Diamond Prices?

Let’s get to the facts.

The 2 big factors that affect the price of diamonds is the 4-C’s (which our well-researched buyers generally already know all about) and their purchase location (and we’ll get to that further down this page). 

Are the differences between all the grades priced the same?

No. The rules of thumb are that:

  • Diamond prices increase with diamond SIZE (largest being most valuable).
  • Diamond prices increase with diamond COLOUR (colourless being most valuable).
  • Diamond prices increase with diamond CLARITY (clearest being most valuable).
  • Diamond prices increase with diamond CERTIFICATION (GIA is the highest standard).

The KEY to getting great value with your purchase is to understand that the price changes for these 4-C’s are NOT linear. This means that there is a sweet-spot combination between size, colour, clarity, certification where you can get the biggest bang for your buck. Locating that sweet-spot is where the skill and experience of your jeweller is demonstrated.

One of the biggest things affecting the price you pay for your diamond is actually ‘where’ you get it from. Meaning, if you’re browsing the high-street retail outlets in every city CBD, or Westfield’s etc, then it’s actually you that pays for that expensive real estate rental embedded within the price of your diamond ring. If the ‘where’ you get it from is a specialist online diamond store like us then you’re extra ‘real-estate-mark-up’ within the price of your diamond will be very low. It’s common sense really. And to that end we’re happy to help you with our free price comparison service. If you’d like to compare the price of a particular diamond that you have been looking at then simply send us the details through our jewellery store contact page and we’ll get back to you with the latest prices, factoring in the current gold and currency exchange rates. That way you’ll immediately know if you have a bargain in front of you and you should grab it before someone else does, or if you’ll save a few hundred, or even a few thousand by continuing your search elsewhere.
