What is the clarity of a diamond?
Clarity refers to the surface irregularities (blemishes) and internal (inclusions) features of a polished diamond. Collectively, these blemishes and inclusions are termed as the diamond’s clarity characteristics. A flawless diamond is one with the highest clarity grade (FL),...
What is a clarity grading?
A clarity grading is given based on the presence and appearance of flaws in a polished diamond. These flaws are placed into two categories; blemishes and inclusions.
What is clarity in a GIA diamond report?
When viewing a GIA diamond report, clarity is an aspect that people pay the most attention to ( mostly because of the plot diagram since we are mentally wired to be more receptive to images ). Clarity refers to the surface irregularities (blemishes) and internal (inclusions) features of a polished diamond.
Should I use a diamond inclusion plot for clarity?
However, when it comes to clarity, your report should be used in conjunction with high-res imaging and a close look at the diamond. The diamond inclusion plot for this SI1 graded stone shows a multitude of different inclusions.
Which clarity characteristic occurs when too much pressure?
BeardingBearding – Tiny hair-like fractures that extend into the diamond from the girdle. (The girdle is the dia- mond's the outer edge.) Bearding often occurs when too much pressure is used while shaping the diamond in cut- ting.
Which clarity characteristic can occur when loose diamonds rub against each other in a parcel?
AbrasionAbrasion: Tiny nicks along the junctions where a diamond's facets meet. Abrasions can occur when loose diamonds rub against each other in a parcel.
Which GIA color grade can be described as essentially colorless?
You can develop similar explanations for other systems, but you might present GIA grades like this: The D grade is absolutely colorless. The next two grades, E and F, are essentially colorless. The differences between D, E, and F are so slight, only experts can see them even when diamonds are unmounted.
How precisely opposite sides of the diamond match is considered when judging the cut quality factor of?
symmetryThe main concern with symmetry is how precisely opposite sides of the diamond match. This is judged from different views – crown, pavilion, and profile.
What changes the clarity of a diamond?
The effect of a clarity characteristic on the clarity grade is based on its size, number, position, nature, and color or relief. The GIA clarity scale includes eleven diamond clarity grades. The scale narrows at the top because there are very few diamonds in the higher clarity grades.
What is feather clarity diamond?
Feather. A general term for any fracture or fissure in a diamond that extends to the surface. In higher clarity diamonds, feathers may be so shallow or low-relief as to be difficult to find even under 10x magnification.
Is F or G diamond better?
As the least expensive color grade in the colorless area of the diamond color scale, an F color diamond offer slightly better value than a D or E diamond. However, most of the time, you'll be better off buying a G or H color diamond over one with an F color grade.
What is Diamond Clarity H?
H color diamonds are part of the “near-colorless” area of the GIA's color scale. This means that they appear almost totally colorless when they're viewed with the naked eye, but could show a slight yellow tint when they're viewed under magnification by an expert gemologist.
What is the diamond clarity scale?
The GIA Clarity Scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories. In determining a clarity grade, the GIA system considers the size, nature, position, color or relief, and quantity of clarity characteristics visible under 10× magnification.
What is the highest possible clarity grade?
flawlessThe highest clarity grade for a diamond is FL, or flawless. The GIA only ever grades a diamond as flawless when it has no inclusions or blemishes that can be seen by a skill grader, even if it's viewed under 10x magnification.
When they formed how many gem quality diamond crystals grow large enough?
The correct answer is A. One gem quality diamond crystal in a thousand grew large enough to yield a high quality finished diamond weighing 1 carat or more.
Which of the following can damage and discolor karat gold and sterling silver?
Chlorine, especially at high temperatures, can permanently damage or discolor your gold jewelry. Do not wear gold jewelry while using chlorine while using bleach or while in a pool or hot tub. You can remove tarnish with jewelry cleaner, or by using soap and water mixed with a few drops of ammonia.
What are Clarity Characteristics?
Diamonds are naturally formed in the earth as a result of intense heat and pressure; these conditions can often result in inclusions and blemishes within, and on the surface of the stone. Like a snowflake, the formation of each diamond is entirely unique and many consider these inclusions ‘birthmarks’ within the diamond.
Clarity Grades
The GIA has six clarity categories, which are then subdivided into 11 specific grades. These grades are:
Can I Rely on my Grading Report?
First, I must point out that GIA or AGS certification is absolutely essential when buying a diamond. It really is the only way to know what you are buying. You can absolutely rely on the GIA to provide you with accurate data regarding the quality of your diamond.
The Final Word
Like a fingerprint, inclusions in a diamond make each stone entirely unique. Small inclusions that are not visible by eye are a precious reminder of the miraculous, natural formation of diamonds within the earth, however larger inclusions and flaws can ultimately be detrimental to the fire and brilliance of your stone.
What is the color of a 6.61 ct diamond?
Left, prior to annealing, this diamond’s color was considered fancy yellow brown. Right, after annealing, this diamond’s color grade is “L” (faint yellow).
What does HPHT mean in diamonds?
HPHT stands for a high-pressure, high-temperature. This treatment is an effective tool for changing the color of certain diamonds, making them colorless, pink, blue, green, yellowish green, or yellow. Outside of a well-equipped grading laboratory, this form of diamond treatment is virtually undetectable.
What is GIA coating?
While many of these are not common in the market, GIA tests every diamond it grades for the presence of diamond treatments. Coating enhances a diamond’s color by masking an undesirable body color with an ultra-thin layer of chemicals or plastics. Another form of coating involves applying a thin film of laboratory-grown diamond to the surface ...
Does diamond treatment affect the value of a diamond?
While diamond treatments can increase a stone’s Color or Clarity, the presence of such enhancements may affect the diamond’s value – particularly if the price reflects its appearance after treatment.
What is clarity in diamonds?
Clarity refers to the surface irregularities (blemishes) and internal (inclusions) features of a polished diamond. Collectively, these blemishes and inclusions are termed as the diamond’s clarity characteristics.
What are the factors that affect the ultimate condition of a diamond?
Besides the forces of nature, rough diamond mining and polishing processes are also factors that affect the ultimate condition of the diamond. Since no two diamonds are alike and do not have the same exact flaws in similar locations, clarity characteristics behave like fingerprints.
