Top Quality Engagement Rings: Choosing The Right Gemstone

You may either choose to buy a quality engagement ring with some real worth/value for your fiancé or fiancée, or you may buy a placeholder or temporary ring for him/her.

The topmost quality and best type of engagement ring for your fiancé/fiancée is an engagement ring with some real worth/value, which should ideally be your first choice. A quality engagement ring with some real worth/value will generally comprise of either a precious metal like gold or a valuable natural gemstone like diamond or both. 

The real worth/value of an engagement ring is the total sum of the real worth/value of its precious metal(s) and/or valuable natural gemstone(s).

You can use the following to chose or select one or more valuable natural gemstones with or for a top quality engagement ring with some real worth/value, for your fiancé/fiancée.

You can also use it to quickly determine if an engagement ring is a quality ring or not by simply checking the quality of its gemstone. An explanation on how to determine the quality of an engagement ring’s gemstone is available below.

Diamond And Non-Diamond Gemstones

Gemstones can generally be classified as diamond and non-diamond. Diamond gemstones can be colored or colorless, non-diamond gemstones are other gemstones apart from diamonds.

The quality of all types of natural gemstones except pearls are determined by their cut (proportion), clarity (flawlessness) and color grades while their real worth/values are determined by their cut, clarity, color and carat (weight) grades/values. Pearl as a gemstone uses a different set of grades.  


Cut Grades

The cut grades for all natural gemstones (except pearls) are from Excellent to Poor, that is, Excellent, Very Good, Good, Fair and Poor.

The depth % and table % of the cut of a gemstone can be used to further define how well-cut the gem is, both of these are sub-grades of the gem’s cut grade. Both are also more uniformly defined for diamonds than other gemstones. They may also not be available with the description of a ring on a store/jeweler’s website, hence you may have to ask for them directly.


Clarity Grades

The clarity grades for all natural gemstones (except pearls) are from Flawless to Included/Inclusions, that is

*   F - Flawless
*   IF - Internally flawless
*   VVS - Very, Very Small Inclusions (VVS1 and VVS2)
*   VS - Very Small Inclusions (VS1 and VS2)
*   SI - Small Inclusions (SI1 and SI2)
*   I - Inclusions (I1, I2, I3)

Inclusions are gemstone flaws, gemstones with a clarity grade of I (that is, I1, I2 or I3) have inclusions/flaws that may be or are likely to be visible to the eye, I grade inclusions will also have some negative impact/effect on the durability and/or appearance of the gemstone too.

For diamonds, the flaws/inclusions for the other grades’ (that is, IF through SI) cannot generally be seen with the unaided eye without a microscope, that is, they are eye clean.

For colored gemstones with SI1 and SI2 clarity grades however unlike diamonds some inclusions/flaws may be noticeable or obvious to the unaided eye, depending on some factors such inclusions/flaws may however not affect the value of the colored gemstone.


Color Grades

(a).  Colorless Diamonds

The color grades for colorless diamonds are

D, E, F – Colorless
G, H, I, J – Near Colorless
K, L, M – Faint Yellow
N, O, P, Q, R – Very Light Yellow
S-Z – Light Yellow

The more colorless a colorless diamond is the more valuable it will be.


(b).  Colored Diamonds

The color grades for colored diamonds are from Fancy Vivid to Faint, that is Fancy Vivid, Fancy Deep, Fancy Intense, Fancy Dark, Fancy, Fancy Light, Light, Very Light and Faint.


(c).  Other Gemstones (Non-Diamond Gemstones)

The color grades of non-diamond gemstones are specified with a description of their colors, that is, their grades may be described as blue, red, yellow, orangy red etc.

For some non-diamond gemstones, some colors are preferred or in high demand and are therefore more valuable than other colors, some color preference for some valuable non-diamond gemstones are as follows

Sapphire – Blue
Tanzanite – Blue

Two sub-grades of the color grade for non-diamond gemstones, that is, tone and saturation are also used to further define the quality of the gemstone’s color too. Tone defines how light or dark the gem’s color is, while saturation defines the intensity of its color.

For example, the ideal tone and saturation grades for some non-diamond gemstones are

*  Blue Tanzanite
Tone - 4 to 6
Saturation – 5

*  Blue Sapphire
Tone - 7 to 8
Saturation – 6


Both color sub-grades may also not be available with the description of a ring on a store/jeweler’s website too, hence you may also have to ask for them directly. You can learn more about tone and saturation at Finding The Perfect Engagement Ring.

You should note that for all top quality gemstones (that is, for both diamond and non-diamond gemstones) the minimum cut grade is Good, and all the clarity grades are from Flawless to SI.

You should generally use the cut grade of a gemstone to first of all determine how well-cut it is, and then use the depth % and table % of the grade to compare two gemstones with the same cut and specification.

You can use the tone and saturation grades of non-diamond gemstones with their color grades too.

●  Group A
Shape – Round
Luster - Excellent, Very Good and Good
Surface – Clear and Lightly Spotted

Carats And Value

Carats are generally used together with the cut, color and clarity grades of gemstones to determine their worth/values. The higher the quality and grades of a gemstone the more valuable and expensive it will be. The more carats a gemstone has the more valuable/expensive it will also be too.

You can use the cut, color, clarity and carat of a gemstone or the gemstone in an engagement ring to choose or get a gemstone/ring of some specific worth or value. You can learn more about engagement rings and determining their real worth/value at Finding The Perfect Engagement Ring.

All the grades of a pearl gemstone will generally affect its value and the higher or topmost the grades of a pearl gemstone are, the more valuable and expensive it will be too.


Treated Gemstones

If a gemstone is treated (that is, enhanced), its value is usually lower than an untreated gemstone with the same specification.


Other Certificates Institutes Apart From GIA

If your gemstone or engagement ring’s gemstone is graded with some other grading system apart from GIA, you may generally find some information on the internet on how the grades from different institutes can be converted and evaluated with each other.


You can review the cut, color, clarity and carat grades/values of each of the engagement rings on this page to see how some of these can be applied. You may click on the rings to get more details about their specifications.
