What Makes a Diamond Pretty – Part 1

Hi again,

Are you are looking for that special diamond and want to be sure that not only does it have a good grade and certificate, but also that it is a Pretty Diamond? 

Not all certificated diamonds are pretty, including  diamonds with “ideal,” “excellent,” or “very good” cut grades.  The certificate is only the place to start from.  There is much more to understand.  Let me briefly explain, but please do not hesitate to call me if you would like to discuss this most important issue in greater depth.

What do we mean by a Pretty Diamond?

As you probably are aware, prices for diamonds of the same size and grade can vary substantially, sometimes by 20% or more.  Some of the best known on-line diamond retailers have many diamonds listed with the same grade and cut with substantially different prices.  When comparing a grade and a price it can often seem as if the lower priced “ideal” or “very good” cut diamond is a better “deal” than the higher priced diamond.  A closer examination will usually reveal that this is not the case.

When you consider purchasing a diamond you should be looking for a Pretty Diamond!  If the diamond is Pretty (as I am about to define that term for you), all the other factors of the certificate’s statistics will fall into place within the appropriate ranges.  But how can you tell if a diamond is pretty?  You can’t if all you have to rely on is the bare bones of the certificate.  You need expert guidance. 

Let me describe the the first of four major characteristics of a diamond which must be met  to consider the diamond a Pretty Diamond worthy of your investment and consideration.  (If you would like to read about these issues in greater detail, please go to Beyond the Four C’s: What you  should really know before you buy a diamond!)

1. The physical size of the diamond in millimeters has to reflect what a well cut diamond should look like.

For example, a 1.00 carat round diamond should measure approximately 6.5mm in diameter, a 1.50ct should measure around 7.5mm, a 2.00ct should measure around 8.1-8.2mm, and so on.  If you see a diamond listed on line in the 1.00ct size which only measures 6.2-6.3mm (or smaller), you should not buy it!  That diamond doesn’t look any larger than a well cut 0.80-0.90ct diamond.  This also applies to 1.50ct diamonds which measure 7.2 or 7.3mm.  These diamonds may have a good grade on paper, even a terrific cut grade and a “great price” but it is not a diamond I would ever recommend to my private customer.  The same factor applies to fancy shaped diamonds with the additional requirement that the diamond’s shape has to be right, not just its dimensions. Below is a photograph which will highlight for you what I am talking about.  A picture is worth a thousand words.
