Diamond clarity

Information about the clarity of the diamond

By clarity we mean the absence of inclusions. The presence of inclusions visible to the naked eye is referred to as an “included diamond” (I). The degree of clarity of diamonds that are pure to the naked eye is measured with a 10x enlargement and qualified from IF to SI. The very high light refraction index of the diamond and its high power of reflection make it difficult for the naked eye to see the inclusions.

IF	Internally Flawless
	This is defined after a 10x enlargement through a magnifying glass. When purchasing an IF diamond, demand a recognised certificate certifying its clarity.
VVS	Very Very Small inclusion(s)
	Very difficult to locate with the 10x magnifying glass. The location and number of inclusions determine the difference between VVS1 and VVS2. When purchasing a VVS diamond, demand a recognised certificate.
VS	Very Small inclusion(s)
	Difficult to locate with the 10x magnifying glass. Location and number of inclusions determine the difference between VS1 and VS2. Demand a recognised certificate.
SI	Small Inclusion(s)
	Easily () located with a 10x magnifying glass ( easy for an experienced professional) and they don’t affect the brilliance.SI1 and SI2 represent a good clarity, above the quality known as “commercial” that you usually find in shops. A good S “i” is an “i”ntelligent choice (but all Sis are not the same). A certificate is always recommended for diamonds of ¾ ct and more. SI3, a “border-line” category to chose “eyes wide open”. Chose Si3 with off-centred inclusions.
I1	Included
	They are visible to the naked eye (of an experimented professional) and slightly affect the brilliance, but above all they affect the idea of the beauty of the diamond itself.
I2	These inclusions are bigger or more numerous, visible to the naked eye and they diminish the brilliance, even more so for the I3.
