are hazy or milky areas in a diamond. Most clouds are made up of crystals too tiny to see individually even under a 10X magnification.
A visible collection of minute particle matter, such as water droplets and/or ice crystals, in the free air. A cloud forms in the atmosphere as a result of condensation of water vapor. Condensation nuclei, such as in smoke or dust particles, form a surface upon which water vapor can condense.
Water evaporating from the Earth's surface is held as a vapour in rising warm air. As the air cools the vapour condenses into water droplets which form clouds. Clouds are classified into two main groups: cumulus and stratus (massed and layered). Click here.
A visible mass of liquid droplets suspended in the atmosphere above Earth's surface. Clouds generally form in areas where air rises and cools. The condensing water vapor forms small droplets of water (with diameters of about 0.01 to 0.02 mm) that, when combined with billions of other droplets, form clouds. Ever wonder how much a cloud weighs
Assemblies of tiny water and/or ice particles in the atmosphere above the earth's surface.
Tiny visible water droplets or ice crystals suspended in the air.
commonly-used abbreviations for cloud types: AC = altocumulus AS = altostratus CB = cumulonimbus CC = cirrocumulus CI = cirrus CS = cirrostratus CU = cumulus NS = nimbo stratus SC = stratocumulus ST = stratus
A cluster of very tiny imperfections within a diamond. These imperfections will often take on a transparent cloudy look, and will require extremely high magnification in order to be seen.
This is a grouping of a number of extremely tiny inclusions that are too small to be distinguishable from one another, even under magnification. The result of this is that, under a microscope, this grouping often looks like a soft transparent cloud inside the diamond.
Clouds are made up of microscopically small dust-like crystals. When they are small and spread out, they diminish the clarity of the diamond only slighly. When they are large and close together, they influence the transparency and brilliance of the diamond.
a white or gray or almost black mass in the sky made up of tiny drops of water or ice crystals
A type of inclusion in gemstones that usually a cluster of tiny inclusions that create a milky appearance and can greatly affect value.
A cloud is another form of inclusion. But unlike carbon inclusions, which are black, “clouds” are white milky areas that can be inherent in the diamond.
