Diamonds are in a class of their own

Updated: Feb 19

Diamond engagement rings are synonymous with elegance & have endless design possibilities from dazzling intricate settings to a diamond solitaire set simply to show the gemstone off magnificently. Not only are diamonds our gemstone of choice but they are also one of the most scratch-resistant natural materials on earth & are rated 10 on the Mohs scale of hardness.



What factors determine the quality & price of a diamond? 

Beauty is in the eye of the beholder, but diamonds are in a class of their own.  The characteristic of natural diamonds are standardised by the GIA 4C’s, (an recognised international society that offer a grading system that can guide you in making your decisions). To the inexperienced eye most diamonds look the same however, we will put the 4C’s into some perspective by determining value in the order of Cut, Colour, Clarity, & then Carat. At Minturn, we view ‘Cut” the most important as ultimately the cut is the most complex characteristic of a diamond &, the cut of a diamond is introduced to or taken away from, the gemstone material by man. All other attributes of the gem come naturally.

Our goal is to help you choose a diamond that brings you joy & will last a lifetime. So, lets take a quick dive into the basics of the 4C’s.


Cut

Diamond rough is digitally assessed for the greatest yield. Most diamonds are cut with precise geometric dimensions that will function as mirrors to reflect light into the gem from one angle to another before being dispersed back through the top. To cut a diamond so its proportions, durability, symmetry, & polish are excellent is crucial.

These four attributes influence how the brightness of internal & external white light is reflected, & how the “fire & scintillation” are perceived. Fire describes the scattering of white light across the colours of the rainbow, with scintillation describing the sparkle produced (light & dark areas caused by reflection). 

 

Colour

There are various shades of white diamonds with most gems having barely perceptible yellow, grey, or brown tints. The purer the colour the rarer it is & the greater its capacity to reflect & refract light. The highest quality is known as “colourless” (D grade). GIA’s colour grading begins at D & ends at Z. Grading measures the degree of colour compared to master stones of established values, determining the quality & value of the gem. 


Clarity

In natural material inclusions in the interior or blemishes on the exterior add character to your gemstone. These characteristics may interfere with the how the light is reflected or the overall appearance & impact the value of the gem. Most diamonds will “face up” well with its inclusions & blemishes remaining invisible to the naked eye. Without flaws a diamond will have greater scintillation & beauty. 

 

Carat

If you have always dreamt of rocking a big Diamond engagement ring, then carat will be your preference with compromise on the other qualities. Purchasing a diamond that considers the gem size in relation to your hand is important. Larger diamonds of quality are more valuable, desirable & rarer. It does come down to preference, but a diamonds value is determined using all the 4C’s.
