The LeGassick Diamond

LeGassick love diamonds! We pay close attention to each of the 4Cs - Cut, Colour, Clarity and Carat -  ensuring bright, beautiful, sparkling diamonds every single time. Of the 4Cs, cut- its proportion and symmetry- is the most important factor in determining a diamond's beauty, value, and light performance.

Cut

What is Diamond Cut?

Diamond cut is the single most important of the 4Cs when it comes to beauty and sparkle. The cut refers to how a diamonds facets interact with light. It is determined by polish, symmetry and proportion. 

Why is diamond cut so important?

Cut is the only one of the 4Cs that is affected by human hands. Two diamonds may have the same clarity, colour and carat weight, but cut is what determines whether or not one is superior to the other. Put simply, cut is responsible for the quality and degree of a diamond’s sparkle.

If a diamond is cut poorly, it will appear dull even if it has a high colour and clarity grade. If a diamond is cut well, it will reflect and refract light for maximum brightness and sparkle. 

LeGassick hand select all our diamonds to ensure only the best cut diamonds from around the world, those diamonds with a true brilliance and sparkle that needs to be seen, are chosen to become LeGassick diamonds.

Aside from choosing the finest raw crystals and having some of the world's best craftspeople, Hearts on Fire use state-of-the-art technology and tools, making their cutting process a blend of art and science, consistently cutting diamonds to absolute perfection every single time. LeGassick is proud to showcase the “Worlds most perfectly cut diamonds.”

Colour

What is diamond colour?

Diamonds come in a range of natural colours, including pink, blue, yellow, brown and green. When we talk about white diamonds, what we are really talking about is the diamonds lack of colour.  The less body colour, the rarer and more valuable a “white” diamond is.

 

Why is colour important?

Colour is important when choosing a diamond as it directly affects the diamond's appearance. Diamonds with a lower colour grade can appear yellow instead of the desired brilliant white. 
A LeGassick Diamond is always selected with a colourless or near colourless grading. 

Clarity

What is diamond clarity?

Clarity in a diamond is defined as its freedom from natural inclusions, also known as clarity characteristics. A diamond's clarity is a measure of the purity and rarity of the stone, graded by the visibility of these characteristics under 10-power magnification.  

A LeGassick Diamond is chosen to be free from inclusions that will inhibit the diamonds brilliance or quality and are generally difficult to see with the naked eye. You never have to worry about seeing any major inclusions in a LeGassick diamond—our diamonds are consistently chosen for clarity ratings, ranging from Flawless (absolutely no inclusions) to Slightly Included (slight characteristics that can only be seen under 10X magnification, and are generally not visible to the naked eye).  

Carat

What is a diamond carat?

Diamonds are broken down into carats and points, 100 points = 1.00 carat. Though diamond carat weight is the factor which most affects the price of a larger diamond, cut is the factor that determines how much sparkle and outward beauty it will have.
It’s important to keep in mind that carat refers only to a diamond’s weight, and not necessarily to its size. Even if two diamonds have the same carat weight, the cut of the diamond will affect how large the diamond appears, and how much sparkle it emits. 
A LeGassick diamond is always chosen for it's beauty and brilliance, not for carat weight and size.

A LeGassick Diamond truly is a whiter, brighter,
more beautiful diamond.

Responsible Sourcing Standards

The Kimberley Process is an international, cooperative diamond monitoring system designed to eliminate the flow of conflict diamonds, or “blood diamonds.”  The 75 member countries that participate in the Kimberley Process agree to trade strictly within the organisation and require that all rough diamond imports be accompanied by documentation issued by the originating foreign participant.

LeGassick only works with vendors and purchases diamonds from countries that adhere to the Kimberley Process.
