Beautiful. Rare. Cherished. 

Each diamond is unique and is a miracle of time, place and change. Each diamond has specific qualities that establish its value.

The Gemmological Institute of America created the first, and now globally accepted standard for describing diamonds: Colour, Clarity, Cut and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

 

 



 

 

Diamond Colour 

Diamond Colour Actually Means Lack of Colour

A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z diamond colour-grading system measures the degree of colourlessness.

Many of these diamond colour distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price

 

 

 

 

 

 

 



 

 

 

Diamond Clarity

Diamond Clarity refers to the absence of inclusions & blemishes

Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’

Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher its value.

 

 



 

 

Diamond Cut

A Diamond's Cut Unleashes it's Life

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, heart, oval, marquise, pear), but a diamond’s cut grade is really about how well a diamond’s facets interact with light.

Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry and polish deliver the magnificent return of light only possible in a diamond.

 

 

 



 

 

 

Diamond Carat Weight

A Diamond's Carat Weight is a measurement of how heavy the stone is

Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams.

Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. 

 

 

 



 

 

Every Diamond is unique as no two will have the same characteristics. This is why every diamond used for Holly Robinson Jewellery is selected in person after careful and thoughtful analysis on each stones grading. 

I personally select each diamond to ensure every client benefits from my wholesale connections, GIA trained eye and very particular standards! 

Each Diamond is selected based on the 4Cs, your price range and any specific requirements you may have.
