2020年6月20日 · There are 3 clarity grades in all with Piqué: P1 (Piqué 1, or 1st Piqué), P2 (Piqué 2, or 2nd Piqué), and P3 (Piqué 3, or 3rd Piqué)… P1 is the highest of the bunch, then P2, followed by P3 at the bottom of the bucket (P3 is the lowest clarity grade there is). Piqué is the equivalent to GIA’s “I clarity range“, which is I1, I2 ...

The quality and value of a diamond is defined according to the 4Cs: carat, colour, clarity and cut. At HRD Antwerp we are experts in analysing these characteristics. Our diamond grading report covers all 4Cs for loose diamonds, ensuring consumers know …

Beyond I3 there are Diamonds that have inclusions visible to the naked eye: these are referred to as Pique or PK and some in the industry often talk about them as “frozen spit”. As a rule of thumb, if you are buying a Solitaire Diamond Ring you should try and purchase an I1 or above.

Using GIA’s International Diamond Grading System™, diamonds are assigned a clarity grade that ranges from flawless (FL) to diamonds with large inclusions and surface faults (I3). The GIA Clarity Scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories.

Diamond clarity determines the stone's value by assessing tiny flaws within the stone and slight imperfections on its surface. Most such flaws are invisible to the naked eye and rarely affect the beauty of the stone. For this reason, gemologists often refer to them as internal characteristics rather than flaws.

Clarity relates to markings that naturally occur within the diamond. The grading system starts at FL for flawless, to IF internally flawless, VVS very very slightly included, VS very slightly included, SI slightly included, and I included (also called pique). Diamonds are graded for clarity under 10X magnification. Mos

Piqué is the equivalent to GIA’s “I clarity range“, which is I1, I2 and I3. Piqué is used in just about every country, even the US. But since GIA devised the standards for grading diamonds ( the 4 C’s ), and they called this lowest clarity range “ included ” or “ imperfect “, that’s what is common in the states, and that’s ...

The Pique Function is a revolutionary inclusion feature enables calculating positions and grading clarity as viewed by the user. Once the software scans the diamond you can detect the pique's reflection on a video screen and mark it on both sides.

I1/I2/I3 (P1/P2/P3) - Inclusion or Pique. A stone that has inclusions most often visible with the naked eye. Inclusions of this level drastically bring down the diamonds value.

In earlier days, clarity grading had two definitions: "pure" for clean diamonds and "pique" for spotted diamonds, while diamonds which showed no inclusions under slightly magnifying loupe were called "loupe clean". Modern Diamond Clarity Grading System
