Carat

The unit of measurement of diamond weight is the carat. The weight is the most important criteria in determining the price of a diamond. Santa Lomas offers diamond solitaires in a large range of carats according to the setting. All Santa Lomas diamonds solitaries are certificated by GIA.

Cut

The natural beauty of a gemstone can be enhanced by the way it is cut. Process of cutting a gemstone improve its beauty and making it reflect more light. The is a big variety of cut you can find in Santa Lomas.

Clarity

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. If you are trying to determine what is the best clarity for a diamond, remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity. We use the GIA Diamond Clarity Scale for 6 categories, some of which are divided, for a total of 11 specific grades.

– Flawless (FL) No inclusions and no blemishes visible under 10x magnification
– Internally Flawless (IF) No inclusions visible under 10x magnification
– Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
– Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterized as minor
– Slightly Included (SI1 and SI2) Inclusions are noticeable under 10x magnification
– Included (I1, I2, and I3) Inclusions are obvious under 10x magnification which may affect transparency and brilliance.

Colour

A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. We use GIA’s D-to-Z diamond colour-grading system. It measures the degree of colourlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established colour. These distinctions make a very big difference in diamond quality and price.
