Diamonds' Grading and Certification

Engagement rings with a centre diamond of 0.5 ct or above include an individual IGI or GIA certificate. Other jewellery, including bracelets, bands, necklaces and earrings, may be certified as a complete jewellery piece rather than per individual diamond, by IGI, SGL, IDL, IDT or HRD institutions.

Carat

Carat weight has the most influence on diamond value. The weight or size of a diamond is measured in carats (ct.).
Diamonds of different shapes may appear different sizes for the same carat weight.
One carat weighs 1/5 of a gram and is divided into 100 points. For example: 0.75 carat = 75 points 1/2 carat = 50 points 1/4 carat = 25 points
When diamonds are mined, large gems are discovered much less frequently than small ones. This rarity makes large diamonds much more valuable.
Diamond prices rise exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality.

Color

All the white diamonds of The Diamond Oasis jewellery are graded as D-E-F (colorless).
Diamonds are graded on a scale from colorless to light yellow or light brown. D-F falls within the colorless range, which is considered the rarest and most expensive.
Fancy colored diamonds are those with hues other than yellow or brown, and they are graded separately.
The color of diamonds is determined by comparing them to a master set of stones ranging from D (colorless) to Z (most yellow/brown).
IGI assigns color grades for diamonds in the D-Z range by viewing them through the pavilion in a neutral environment to ensure accuracy.

Clarity

All the diamond of The Diamond Oasis are minimum VS1 clarity - no inclusions can be seen with human eye.
Clarity evaluates a diamond's freedom from internal and external characteristics that occurred during formation, polishing, or wear.
Clarity characteristics include inclusions (internal) and blemishes (external).
Grading the clarity involves observing the number, nature, size, and position of these characteristics.
IGI grading reports include diagrams showing clarity characteristics, marked in red for internal and green for external features.

Cut

All the diamonds of The Diamond Oasis have either Excellent or Very Good Cut
Cut quality significantly affects a diamond's appearance, including its brilliance, dispersion (fire), contrast patterns, and scintillation (sparkle).
Man-made factors such as planning, proportions, cutting precision, and finishing details determine the diamond's visual properties.
Diamond faceting has evolved over time, with different shapes and cutting styles available.
