A diamond engagement ring is a special purchase and carries a lot of emotional weight. As such, it is completely normal to feel stressed out about the shopping process especially if you are a first-timer.

Given the complexities in navigating the world of diamonds, how do you make the best decisions to pick out a breathtaking engagement ring? To begin with, it is important to understand the basics of diamond quality and how diamonds are classified in the market.

In this guide, I will provide you with a starting point to the ubiquitous diamond quality chart and highlight the 4Cs you need to know. I will also reveal some practical insights to help you get better value for money when choosing a diamond.

Primer on 4Cs of Diamond Quality Chart

4Cs of diamond quality chart gia reference

The Gemological Institute of America (GIA) created the 4Cs (cut, color, clarity and carat weight) to establish the quality of a diamond and as a means of universal communication so that consumers across the world know exactly what they are buying.

Each of the 4Cs affects the value of a diamond and are important aspects you need to understand when shopping for a diamond engagement ring.

Cut: The sparkle and brilliance exhibited by a diamond is a result of carefully engineered proportions and precise facet polishing. Cut quality is what determines whether a diamond will look lively or dull and it has the greatest influence on its appearance.

There’s a whole science behind understanding diamond cut and it can get a little technical for beginners. That’s why I’ve broken it down into an easy to understand section here for you to read.

Color: Diamond color is graded on a scale of D (colorless) to Z (light yellow/brown). The market places a price premium on colorless diamonds due to their relative rarity and popularity with consumers. In real life, the differences between color grades are very subtle and not easily picked out by the untrained eye.

However, many consumers wrongly believe that the better the color grade, the better the sparkle a diamond has. Color grades do not define a diamond’s sparkle. Cut does.

Clarity: The majority of natural diamonds have some form of impurities and clarity is an assessment of the inclusions found in the polished diamond. The quantity, type, location and visibility of the inclusions will determine the clarity grade and correspondingly, affect the value of the diamond.

Clarity is also the most misunderstood attribute of the 4Cs as many people get too hung up on buying higher grade diamonds which are more expensive. In reality, most inclusions above an SI1 clarity grade are invisible to the naked eye. For practical shoppers who want to get better value for money, I generally recommend SI1 or VS2 diamonds that are eyeclean because this helps you avoid the premium for higher clarity grades in the diamond quality chart.

Carat Weight: The weighing unit for a diamond where 1 carat is equivalent to 200 milligrams. Carat weight is an attribute that people prioritize because of its correlation to the visual size of a diamond. It is also important to note that diamond prices rise exponentially as carat weight increases.

Diamond Classification And How It Affects Prices

The price of a diamond is largely determined by the 4Cs found in the diamond quality chart. However, it is important to note that a variety of factors and nuances can affect the value of a diamond. This is what makes pricing a confusing topic for many beginners.

First of all, I want to point out the obvious that the value of a diamond would increase due to rarity factors like carat, color and clarity attributes. With all other things being equal, an internally flawless diamond is more expensive than a slightly included diamond. Likewise, a D color diamond is going to cost more than an I color diamond.

However, that’s the surface level of looking at diamond prices because things are much more complex in real life. If you ever wondered why diamonds with similar specifications often have large variations in their prices, that’s because there are subtle details that a grading report doesn’t reveal.

You will often see larger price variations in the SI1 clarity grade due to the nature of inclusions the diamonds have. While 2 diamonds can have the same clarity grade listed in a GIA report, it doesn’t mean that they are both the same!

1.04ct H SI1 diamond – $4,880

1.03ct H SI1 diamond – $5,930

For example, if an SI1 diamond had a single large, black crystal inclusion that can be easily seen by the unaided eye, it is going to be “penalized” compared to another SI1 diamond that is eyeclean and has well-dispersed crystal inclusions.

Likewise, just because a diamond is classified as a triple excellent by GIA for its cut quality doesn’t make it a top notch diamond. A super ideal cut diamond that is engineered for light performance requires more rough material to be used during the polishing process than a generic GIA 3X diamond. While the classification of these diamonds is similar on the GIA scale, the underlying cut quality and cost can differ greatly.

Similarly for color grading, many people fail to understand that the color grade of a diamond exists in a range and different underlying tones. Even though a GIA report doesn’t disclose these details, I color diamonds graded by GIA can have yellowish, brownish or even greyish undertones which impacts the value of the diamond.

Diamond pricing is more of an art rather than a science. In order to get a better idea of whether you are paying a fair price for a diamond, you need to look beneath the surface of the information presented by a grading report.

Many shoppers make a big mistake by buying “cheap” diamonds with underlying problems because their decisions are driven by seemingly lower prices and greed. The sharp and educated shopper who wants a bright, beautiful diamond makes a purchase based on tangible data instead.

And I sincerely hope you belong to the latter camp of shoppers after reading Beyond 4Cs.

The Various Types of Shapes And Classification of Cutting Styles

diamond shapes classification

Diamonds can come in a beautiful array of shapes and cutting styles. Very often, the terms diamond shape and diamond cut are used interchangeably but strictly speaking, they refer to completely different things.

The shape of a diamond basically refers to the outline the diamond has (e.g. heart shape, pear shape and round) and many of these terms are pretty self-explanatory. The cut quality of a diamond refers to the proportions and finishing that the diamond is polished to.

Most of the diamonds sold in the market are round brilliant diamonds that offer good brilliance and can easily complement different ring styles. While the most popular shape is the round diamond, the choice of shape selection is largely up to personal preferences.

If you are still looking around and aren’t sure what you like, check out the following list to find out more about them: Round, Princess, Oval, Cushion, Marquise, Pear, Emerald, Asscher, Radiant and Heart.
