Minute crystals inside the diamond that look like small specks under 10X magnification. A cluster of pinpoints form a cloud. The presence of a single pinpoint inclusion can make the difference between an IF and a VVS1 grade. Pinpoints are found in diamonds of VVS1 and lower clarity grades. Of course if your diamond has a higher clarity grade, the pinpoints may be impossible to see with the naked eye, and may be hard to find under 10X magnification.
DoW does not sell diamonds with significant crystals that have an impact on the diamondís overall brilliance or quality.
