(not an investment diamond, as some sellers mistakenly claim)
When seeking a long-term investment, many people turn to natural diamonds. Although natural diamonds are beautiful, they are not investments. As soon as you leave the jewelry store, your diamond loses tens of percent of its value (VAT and the margin of several dealers). The price of the vast majority of diamonds is thus determined by the market and dictated by supply and demand. The story of diamond investment is merely a tale spun by diamond traders to sell their goods at high margins.
The 4 Cs of Diamonds
To help you navigate the diamond shopping experience and give you the facts, here are the key differences that set natural diamonds apart from lab-grown diamonds.
In the past, there was no universal standard for evaluating diamonds. Traders and jewelers relied on descriptive terms like "river" or "water" to denote highly colorless diamonds, while "Cape" referred to pale yellow diamonds from the Cape of Good Hope region in South Africa. The quality of a diamond's cut was vaguely described as either "well-made" or "poorly made."
This changed in the 1940s when Robert M. Shipley, the founder of the Gemological Institute of America (GIA), introduced the concept of the 4Cs—color, clarity, cut, and carat weight—to help his students understand the key characteristics of faceted diamonds. This concept, though simple, revolutionized the diamond industry.
Building on Shipley’s foundation, GIA President Richard T. Liddicoat advanced the methodology by creating the GIA D-to-Z Color Scale and the GIA Clarity Scale. He also developed scientific methods and procedures for the objective grading of diamonds.
The establishment of the 4Cs and the GIA International Diamond Grading System™ brought about two significant advancements: a universal language for communicating diamond quality and the ability for customers to clearly understand what they were purchasing.
Today, the 4Cs of Diamond Quality serve as the global standard for evaluating any diamond's quality. The GIA, as the originator of the 4Cs and the International Diamond Grading System™, is trusted worldwide by museums, auction houses, and consumers for grading some of nature’s most exquisite treasures.

Cut
The cut of a natural diamond plays a crucial role in how it interacts with light. The Cut Grading System evaluates a diamond's appearance by examining its brightness, fire, and scintillation, which together determine how a diamond reflects light, disperses it into colors, and sparkles.
Achieving maximum beauty in a natural diamond cut requires a blend of artistic skill and precise craftsmanship. Therefore, the diamond cut grade also considers the quality of the workmanship involved, including the diamond's proportions, polish, and overall symmetry.
Carat Weight
The carat of a natural diamond refers to its weight. The term "carat" originates from the carob seed, a small and consistently weighted seed historically used to balance scales in ancient gem trading. This method eventually led to the establishment of the metric carat as the universal standard of measurement.
One carat is equivalent to 200 milligrams. Diamonds weighing a full carat or more are becoming increasingly rare, with supply dwindling and only one major deposit discovered in recent decades.
Clarity
Natural diamonds originate from deep within the Earth and frequently possess unique markings known as inclusions or blemishes. These distinctive features often result from non-carbon elements or disruptions occurring during the intense heat and pressure conditions of a diamond's formation, serving as tiny time capsules that narrate the diamond’s natural history.
Clarity in diamonds measures the absence of these inclusions or blemishes. Diamonds that form without any such imperfections are exceedingly rare and are classified as "flawless" on most grading scales. These flawless natural diamonds are among the most valuable gems in the world.
Color
A natural diamond’s color grade is usually a measure of how colorless the diamond is. Most natural diamonds appear colorless to the average shopper, but actually have slight tones of yellow or brown. The closer the stone is to colorless, the rarer and generally more valuable it is. Natural diamonds are graded on a color scale ranging from D (colorless) to Z (heavily tinted brown or yellow).
Diamonds can also form naturally in almost any color imaginable because of factors apparent in the earth when they form. Most of these natural “fancy” colors are so rare that their value can be limitless, and they are graded on a scale more closely describing the visible color.
