Metal Settings for IGI Diamonds
Platinum
Platinum: Known for its durability and hypoallergenic properties, platinum offers a pure white color that enhances the diamond's natural brilliance.
White Gold
Popular for its elegance, white gold is often rhodium-plated to maintain its luster. However, it may fade over time.
Yellow Gold and Rose Gold
These warm metals can help mask any yellow or brown tints in the diamond, offering a fashionable and unique look.
IGI Diamond Criteria
Carat
Diamonds are measured in terms of weight and we refer to this as carat weight. The carat weight plays a big part in determining the value of the diamond. Lab diamonds are formed differently than natural diamonds, however, they are still measured on the same scale for carat weight which is the main determining factor of size. Because shapes and cutting methods are the same, carat is on the same scale for natural and lab diamonds.
Color
Diamond color is measured on a scale from D to Z, where “D” is equal to a color-free diamond and “Z” implies the diamond has a yellow hue. Experts also check for fluorescence. Fluorescence is if the diamond emits light when under a UV lamp. The fluorescence scale runs from “none” to “strong.” While lab diamonds are affected differently by the environment in which they are created, there are still grades and variations in the color. They can be affected by the seed quality and the other elements that can be introduced to the diamond while it is being grown.
Clarity
Gemologists use x10 magnification to get a close up look at the clarity of the diamond. The scale runs from “I” (included) which indicates visible flaws, to “FL” (flawless), which indicates no flaws can be seen - even when the diamond is magnified. Inclusions form much the same way in natural and lab grown diamonds.
Cut
The cut looks at a number of elements, including how well the diamond is polished (smoothness) how symmetrical the diamond is (cutting precision) and proportions (measurements including crown height, table, etc). Grade wise, cutting is rated from “poor” through to “excellent.” Cutting is a factor of how well diamonds are cut from the diamond rough that is formed in the lab. Cut is the most important 4C to consider.
