Not all gemologists, however, are competent with spectroscopic procedures, and some fancy color diamond require examination with very sophisticated equipment not available to most labs. If you have already proposed and are ready to purchase the ring, take your loved one with you when selecting a ring. If you are purchasing a ring prior to the proposal, consider retrieving (also known as sneaking) one of the rings she already owns and taking it with you.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Proportions of the premium cut diamonds are very close to ideal cut. Premium cut diamond may be close to the ideal cut proportions and look just identical. By all means such diamonds are considered well cut. In fact, many consumers cannot distinguish between the ideal cut diamond and the premium cut. Appearance of diamond is very subjective and cannot be fully evaluated just by their proportions along.
Color An E color diamond is extremely rare and slightly less expensive than a D but is so similar that most people won’t be able to tell the difference. You pay a serious premium for an E color diamond. Diamonds of this color grade will appear colorless even when observed face down.
Clarity Diamonds of SI3 clarity are on a borderline between slightly included and included diamonds. SI3 grade inclusions are almost obvious under 10x magnification. Inclusions in such diamonds may be noticeable to the unaided eye. However, when observing the diamond "face up" as it is mounted in a ring, the inclusions are usually not visible.
