Virtually all diamonds have imperfections called inclusions and blemishes--scratches, trace minerals or other characteristics that can detract from the beauty of a diamond. Diamonds that are absolutely flawless are the most rare, and therefore, the most expensive.

Under the scrutiny of a jewler's 10x magnifying loupe or microscope, inclusions may be seen. These are nature's birthmarks; they may look like tiny crytals, clouds or feathers. The larger the inclusion, the lower the grade and the less rare the diamond.

The number, color, type, size and position of surface and internal flaws affect a diamond's value. Major inclusions can interfere with the path of light that travels through a diamond, diminishing its brilliance and therefore its value.
