Diamonds
Flawless
Flawless is a clarity grade used to describe diamonds that have no visible inclusions (internal flaws) or blemishes (external flaws) under 10x magnification.
Flat Diamond
A flat cut diamond refers to a diamond that has a shallower cut, where the crown (the upper portion of the diamond) is flat or only slightly angled, and the pavilion (the lower portion of the diamond) may also be less pointed.
Flash Effect
The flash effect in a fracture-filled diamond refers to the dispersion of light and the sparkle that occurs as the diamond is moved or rotated, much like in any other diamond.
Feathers
A feather in a diamond refers to a type of inclusion that resembles a small crack or fracture within the stone.
Fancy Colour
Fancy coloured diamonds are natural diamonds that exhibit intense colours beyond the typical white or colourless range.
Faceted Girdle
A faceted girdle in a diamond refers to a girdle that has been polished and cut into small facets, rather than left rough or bruted.
Facets
A facet is a flat, polished surface on a diamond that interacts with light to create brilliance, fire, and scintillation.
