Preferable Inclusions

  • A diamond is graded according to the presence or absence of internal and external characteristics of a diamond. These identification characteristics are also referred to as inclusions (internal characteristics) and blemishes (external characteristics). There are five types of preferable inclusions that can be found even in the highest quality of diamonds:
  • Preferable type of inclusions Definitions
    Pinpoint This is a tiny, usually whitish dot which usually appears individually or in clusters. They are tiny and can only be seen using high magnification. Sometimes, they are not even findable using the standardized 10 time’s magnification.
    Feather A small feather is an extremely minor flaw if it is internal and is not aligned together with a blemish on the same plane. It is faint in colour, usually in white, and is common amongst high quality diamonds. However, a large, extensive feather on the top of a diamond can be an identifiable flaw.
    Cloud A cloud is a small cluster of pinpoints. They are often not visible and can only be spotted within higher degree of magnification. Typically a small cluster of cloud on the table, being the largest facet of a diamond, can be considered acceptable if it does not affect the diamond’s visual appearance with the naked eye.
    Needle Needles are tiny pin-liked inclusions which are often white in colour. They are small and difficult to spot, rendering them a preferable type of inclusion in higher quality diamonds.
    Small, white crystals Crystals are common inclusions of diamonds. They can appear black, brown, grey or white. All diamonds that Bee’s Diamonds carry only possess white crystals. They are preferred to be located on the side and edge of a diamond, to avoid intervention of reflection. However, a cluster of crystal is not preferred as it can potentially lower the clarity grade from Very Slightly Included (VS) to Imperfect (I).
    Indented Natural A natural is a remnant of the original skin of a diamond, and is often left on the girdle by the cutter in order to get the largest possible diameter from the rough. They are usually seen on the girdle and appear to be a rough, triangular, unpolished area. Indented naturals generally do not affect a diamond’s roundness. They can look like a scratch line or a small triangle (called a trigon). They can only be founded in natural diamonds.
