Selecting One Carat Diamond Rings

One Carat Diamond Rings are graded for certification by laboratories using grading criteria. Four of these criteria are critical to understand when making a diamond purchase or investment. Known as the “Four C’s” these criteria are: color, cut, clarity and carat.

Color is the result of the composition of a diamond and it does not change. When a jeweler is describing the color of a diamond they are referring to the presence or absence of color in white diamonds. Because a diamond with no color allows maximum light to pass through, colorless one carat diamond rings are preferred for their sparkle. color1

Cut refers to a diamonds reflective quality. Most one carat diamond rings are cut with 58 facets. The brilliance of diamonds is heavily dependent on the cut. The different angles and the finish of a diamond determine its ability to reflect light and cause its brilliance and fire. Remember that the cut of a one carat diamond ring can have an impact on its durability as well as its beauty. Some cutting faults can make a diamond prone to breakage. A diamond that is cut too thin can also cause light to leak out of the back and the diamond will lose some of the sparkle and appear not to shine. So, as you can see the Cut is probably the most important of the Four C’s.

During the formation process, inner flaws, or inclusions occur in most diamonds. The number and size of these inclusions determine what is referred to as the clarity of a diamond. One Carat Diamond Rings that are clear create more brilliance and therefore are rarer and highly priced. To be considered“flawless”, a diamond must have no surface or internal imperfections visible upon being viewed by a skilled diamond grader using 10 power magnifications.

Carat is the unit of weight by which diamonds are measured. One carat is equal to 200 milligrams. A carat is divided into 100
segments called points. 150 points would equal one and a half carats. When you go to the store to make that all important diamond purchase, do not be shy! Ask questions, get the answers needed to make an informed purchase. Shopping for one carat certified diamond rings enables you to make an informed selection. Knowing the “four C’s” allows you to comparison shop and purchase the best diamond at a fair price. But, before making a purchase, shop around and decide what shapes and styles really appeal to you. Enjoy your one carat diamond rings for years to come!

One Carat Diamond Rings' Clarity

A one carat Diamonds' Clarity can have a large impact on beauty and price. Clarity is an important aspect of a one carat diamond ring, and it is important to know how to grade the clarity of a diamond before you buy one carat diamond ring. It is actually quite easy to learn how to grade the clarity of a diamond. There are basically two things that you must understand: Diamonds with visual inclusions and blemishes, and
those that are ‘eye clean’ meaning that there are no inclusions or blemishes that can be seen with the naked eye. From there, the
clarity of a diamond is further broken down into subcategories.

Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so. Clarity actually refers to the internal and
external imperfections of the diamond. The best one carat diamond rings, of course get a grade of FL or IF – Flawless or Internally Flawless –
meaning that it is perfect. A grade of I-1, I-2 or I-3 means that the diamond is imperfect, with a grade of I-3 being the worst.

Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is slightly imperfect.

The Diamond Clarity’s Chart

Clarity Is Measured On A Scale Of FL to I3.

*(FL=Flawless) Flawless Means No Inclusions Or Blemishes Of Any Kind When Examined By A Skilled Grader Under (10X) Magnification

*(IF=Internally Flawless) This Means No Inclusions, and only insignificant surface blemishes are present.

*(VVS1 & VVS2= VERY VERY SLIGHTLY INCLUDED)

*(VVS1) Inclusions in this grade can be EXTREMELY DIFFICULT to see and are only visible from the pavilion, and only with (10X) magnification.

*(VVS2) Inclusions are still difficult to see but easier than (VVS1) You would most likely need (10X) magnification to see them. It is unlikely that the naked eye would be able to see any inclusions in a VVS2 diamond.

* (VS1 & VS2= VERY SLIGHTLY INCLUDED) Minor inclusions are present. These inclusions are SOMEWHAT easy-to-Difficult for a trained grader to see under 10x magnification. It is still unlikely that a naked eye would be able to detect these inclusions.

FL to VS Grades Could Be Considered Unnecessarily Good-Or Luxury Grade. If The 4 C's Are Well Balanced, An (SI) Grade Diamond Can be Very Impressive! The Engagement Ring Above Has An (SI) Grade Center Diamond
* (SI1 & SI2= Slightly Included) Inclusions are seen easy-to-very easy by an experienced grader using (10X) magnification. Possible For the naked eye to see the inclusions without the aid of magnification if looking at the diamond CLOSELY. This would be more true of an (SI2)

When shopping for a one carat diamond engagement ring, these two grades are certainly worth Considering. Especially if you are working with a limited budget.

* (I1/I2/I3= IMPERFECT!!!) OBVIOUS INCLUSIONS-These Inclusions Can Usually be seen VERY EASILY without magnification. Inclusions in I3 Diamonds may even THREATEN the durability of the diamond.
