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
- 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
- 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 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.
