Big diamonds, it is all relative…
Where do you start when looking for the right diamond? Like everyone… online!
Online is great to get a feel for what is available, it is great for getting an idea of potential costs for a particular type of stone. It is great to learn the basics of diamond qualities. The first place I advise my clients to visit is GIA.edu
There are many websites which sell diamonds (some very successfully) they have all of the bells and whistles, filters, video, images and much more. The majority of these sites do not hold the stock it is simply a spreadsheet loaded up from many dealers across the world.
I am going to assume you already know the 4 C’s (Cut, Colour, Clarity & Carat Weight) so I wont go into it in to much detail in this article (but will soon). The 4 C’s is a simple set of criteria which can be allocated a grade or measurement, the problem with it is, it can be relied on too heavily when someone with a little bit of info from google searches is looking to put a price on a stone.
You have to remember natural diamonds are created underneath continental plates over 150km below the surface of the Earth with massive pressure and heat of over 1050 °C, brought up to the surface by volcanic activity, it is this process that makes every diamond totally unique so simply assuming just because a diamond is graded as Round Brilliant, E Colour, VS1 & 1.50ct in weight it will be the same price as another of the same grade is naive at best.
The problem is the stone at the cheapest price ALMOST ALWAYS wins out for those who have a little bit of knowledge and assume incorrectly because a stone ticks the particular 4 C’s they are looking for it is perfect. There can still be massive variances in price for reasons someone with limited diamond knowledge can not understand.
I am contacted daily through my instagram page by people asking for quotes and advice which I really enjoy engaging with but it can be really tricky to explain to someone that a 3ct round brilliant diamond for €25,000 of a high enough quality for me to stand over does not exist no matter if you are in Dubai or Dublin.
As a diamond dealer who sells stones worldwide I work off percentages and at a particular quality level only. The easiest way to price group diamonds by quality is base it off the type of car you would drive. A Fiat Punto quality 3ct Diamond will be approximately €25,000 I do not work in this quality but many others do, a Mercedes quality 3ct Diamond may be €40,000+ you can also go to the Bugatti level for a 3ct for €100k+ and everywhere in between. All stones will sparkle all stones are natural diamonds one will suit one person where as the others will suit someone else that is why you need an expert on your side when picking the right diamond for you.
