If J is a description of the colour of a white diamond, that grade is given to the near colourless diamonds.
You can learn more about this grade from the chart, below, which shows you the full colour range of 'colourless diamonds' from D to Z.
NVC 10 on a diamond ring typically refers to the clarity and quality of the diamond. "NVC" can indicate a specific grading system or brand, while "10" usually denotes a quality rating, often on a scale where higher numbers represent better quality. It is important to check with the jeweler for precise definitions, as these codes can vary by manufacturer or grading authority. Always ensure you have a certificate from a reputable gemological institute for clarity and quality verification.
The term is 'eye jay' (I-J) and the classification indicates a 'near colourless' white. You can read more about this classification and see it in context, below.
Depends on your grading scale, but an 88 percent would probably be a B+ (good job!)
"14k F G J" typically refers to a piece of jewelry made of 14-karat gold with specific gemstone characteristics. The "F," "G," and "J" likely indicate the color and clarity grades of diamonds or gemstones, following a grading scale. In this context, "F" represents a color grade of "Colorless," "G" is "Near Colorless," and "J" is "Slightly Tinted," with higher grades indicating better quality.
Proof
The grading report or the diamond certificate enlists the individual characteristics of a particular diamond stone. To ensure the genuineness of diamond jewelry, it is important to demand its grading report from the seller before buying.
In grading a diamond's clarity, VS indicates Very Slight.
In diamond grading, "J" clarity refers to diamonds that have noticeable inclusions when viewed under 10x magnification. These inclusions may affect the diamond's brilliance and transparency but might not be visible to the naked eye. J clarity diamonds are considered lower on the clarity scale, but they can still be a good choice for those looking to balance quality and budget.
The indicator E-F in diamond grading may indicate a colour range for a white diamond. It is in the most desirable range, also known as colourless. You can review the colour range, below.
The 4 C's of diamond grading include the carat weight, cut, color and clarity. When one decides to buy a 4 C's diamond, one should consider the cut of the diamond, which is how the diamond appears in terms of proportions and brightness.
"fcly" is not a commonly recognized term in diamond color grading. The standard diamond color grading scale ranges from D (colorless) to Z (light yellow or brown). If you have more context or information, I can try to provide a more accurate answer.

A certified diamond has been inspected and and graded and registered according to GIA (Gemological Institute of America) standards. A diamond grading report is issued showing a comprehensive analysis of the diamond.
The standard magnification for diamond clarity grading under FTC guidelines is 10x. This level of magnification allows gemologists to accurately assess the internal characteristics of a diamond to determine its clarity grade.
AA 5 has several meanings, depending on the context. It is apparently a rating system in Great Britain for lodging. (AA, 5 diamond.) For diamond stones, this rating is sometimes applied to jewelery-grade black diamonds, as a grading system for clarity. This is not a grading scale used by the Gemological Institute of America or the European grading scale. It is a scale used, however, for industrial diamonds, according to the link, below.
P2 is a grading indicator used by gemologists certified by other than the Gemological Institute of America (GIA). P2 corresponds to the GIA grade I2: at least two (visible) Inclusions. You can read more about diamond grading by different gemologists, below.
H1 is not a common notation for describing a diamond. H is one description for a colour. Numbers usually follow V, VV, or VVS; S, SI and so forth, indicating the number of visible flaws in a stone. H1, then, may be a typo in a description.
