<h2 class="wp-block-heading">High-quality gemstones</h2> <p>All of our Gemologists are graduates of the <strong>Gemological Institute of America</strong> (GIA) and have many years of industry experience. Our staff are required to continually improve upon their education and training by regularly attending seminars, lectures, and <strong>advanced gemological studies</strong>, including the coveted and highly regarded, Fellowship (FGA) through the Gemological Association of Great Britain (Gem-A).</p> <h2 class="wp-block-heading">Gem-quality diamonds</h2> <p>The colour evaluation of most <strong>gem-quality diamonds</strong> is based on the lack of colour. A pure and structurally perfect diamond has no hue, similar to a drop of clear water, which gives a diamond a higher value. The D to Z colour-grading assess the presence or lack of colour by comparing to master stones, stones that are of established colour value.</p> <h2 class="wp-block-heading">Gemstone cut</h2> <p>Diamonds are known for being able to transmit intense light and sparkle. We think of a diamond’s cut as it's shape, either round, emerald, pear-shaped. If a diamond’s cut grade is about how well a diamond’s facets interact with light, precise artistry and workmanship are needed to shape a stone so its proportions, symmetry and polish to deliver the magnificent return of light only possible in diamonds.</p> <h2 class="wp-block-heading">Diamond clarity</h2> <p>Natural diamonds are carbon exposed to tremendous heat and pressure, caused by volcanic activity in the earth. This process results in internal characteristics called inclusions and external characteristics called blemishes. Evaluating a diamonds clarity involves determining the size, relief, nature, and position of these characteristics and how this affects the overall appearance of the diamond, no diamond is perfectly pure, the closer it is to be pure, the higher the value.</p> <h2 class="wp-block-heading">Diamond carat weight</h2> <p>A <strong>diamond's carat weight</strong> is the measurement of how much a diamond weighs. A metric carat is defined as 200 milligrams. Each carat can be divided into 100 ‘points. This allows very precise measurements to the hundredth decimal place, a jeweller will describe <strong>t</strong>he weight of a diamond which is below one carat by its points alone.</p>
