Your Guide to Buying One Carat Diamond Earrings

A pair of diamond earrings is often regarded as an indispensable element in a jewellery collection. Although generally considered the world's most precious gem, a diamond can work equally well with affordable way to add diamonds to one's collection.

Before purchasing a pair of one carat diamond earrings, it is important to understand the "four C's" of diamond evaluation: cut, colour, clarity, and carat weight. These factors affect the stone's appearance, particularly its ability to reflect light with brilliance and fire. In addition, it helps to have an idea of what shape and design is most fitting to the wearer, depending on their style. Informed buyers can assess a diamond's individual qualities and find a beautiful pair of one carat diamond earrings that fits within their price range.

History of Diamonds

Early accounts of diamonds come from Sanskrit writings dating back to the fourth century B.C., when they were already considered valuable. Their use in Europe began in the thirteenth century, when small amounts of diamond were used to adorn royal garments and regalia. In the sixteenth century, with developments in faceting, larger stones were used, and the diamond became a more prominent feature. In France, diamond was originally reserved exclusively for the king's use, but a century later diamonds were worn by aristocrats and even members of the merchant class.

Vasco de Gama's 1499 discovery of the passage to the Orient via the Cape of Good Hope meant that Europeans could trade directly with India, then the only source of diamonds. The eighteenth and nineteenth centuries saw an increase in the supply, boosted by trade with South America, the discovery of diamonds in South Africa, and the sale of the French crown jewels after the death of Napoleon III.

Diamond mines are located in at least 25 countries worldwide, excluding Europe and Antarctica. About 130,000,000 carats of diamonds are mined annually.

Conflict Diamonds and the Kimberley Process

One issue in the diamond industry involves the issue of conflict diamonds, also referred to as blood diamonds. These have been sourced from mines that are run by forces opposed to internationally recognised governing bodies. Profits from these diamonds help fund arms purchases, illegal activities, and military actions against those governments.

The Kimberley Process, introduced by the United Nations in 2002, is meant to be a way of certifying a diamond's origin, so as to distinguish responsibly-mined diamonds from conflict diamonds. Many diamond retailers now adhere to the Kimberley Process.

Understanding Weight: One Carat Diamond Earrings

Diamonds are measured according to weight in carats (ct). The term carat derives from the carob seed, whose consistent size and weight was used to balance the scales when measuring gems. One carat weighs 200 milligrams, or 0.2 grams.

For diamond earrings, the weight expresses the sum of the two individual stones. For example, in a one carat pair of diamond studs, each stud weighs 0.5ct.

Diamonds are most commonly mined in small quantities; larger stones are much more rare, which explains why heavier diamonds are costlier than their weight in two smaller diamonds of equal quality.

Diamond Cut

Most gemmologists consider the cut of a diamond to be the most important factor. Diamonds are cut by skilled professionals, ideally to maximise the stone's reflective qualities. Facets are cut into the stone to create a myriad of tiny sides from which light bounces. Proportions must be controlled since being too shallow or deep results in a loss of light through the bottom or the sides. For an ideal cut, some mass of the stone must be sacrificed; deeper or shallower cuts are an attempt to preserve the size, while compromising some of its reflective capacity.

Diamond Cut Ratings

Diamond cuts are evaluated according to their reflective capacity. The following chart outlines the ratings.

Cut Grade



Highest possible rating; maximum amount of brilliance and fire

Very Good

May have overlapping qualities with an "ideal" cut, possibly with some reflectivity sacrificed to preserve size of stone; slightly less expensive


Most light that enters is reflected; however, may be shallower or deeper to optimise stone size


Focus on size rather than brilliance; still a quality cut

Buyers should keep in mind cut's relation to the brilliance of a diamond. Smaller diamonds with a quality cut are often more beautiful than heavier ones with less reflective capacity, and because of their cut, they appear larger than they are.

Diamond Colour

Diamonds are also evaluated according to colour. The presence of nitrogen in some diamonds gives them a yellowish tint, which in some cases can affect the stone's transparency and therefore brilliance. Therefore, many gemmologists regard colour as the second-most important factor in choosing a diamond, after cut.

Diamond colour is graded from D to Z, with D indicating a perfectly colourless diamond: the most desirable and valuable grade. Gradations in colour can be exceedingly subtle, however, so that the naked eye would have difficulty differentiating between some of the different colour ratings. In general, they break down as follows: colourless (D, E, F), nearly colourless (G, H, I, J), faint yellow (K, L, M), very light yellow (N, O, P, Q, R), and light yellow (S, T, U, V, W, X, Y, Z).

Diamond Clarity

Clarity ratings describe the amount of marks, or flaws, a diamond possesses. Internal marks are called inclusions, while surface marks are called blemishes. Inclusions are a natural feature of the stone created during its formation and may include clouds, feathers, crystals, or knots. Blemishes occur during the cutting and polishing process. The chart below explains the different grades of clarity.

Clarity Grade


Flawless (F)

Magnified ten times, no inclusions or blemishes can be detected; exceptionally rare

Internally Flawless (IF)

Magnified ten times, no inclusions, but may may have miniscule blemishes; extremely rare

Very, Very Slightly Included (VVS1, VVS2)

Indicates presence of a few very small inclusions and/or blemishes that are difficult to perceive when magnified by ten; excellent quality

Very Slightly Included (VS1, VS2)

Indicates presence of very small blemishes or inclusions, such as clouds, feathers, or small crystals, which can be observed with effort when magnified by ten; high quality

Slightly Included (SI1, SI2)

Indicates presence of inclusions such as clouds, feathers, or knots, which are visible when magnified by ten, though very difficult to detect with naked eye; good quality

Included (I1, I2, I3)

I1 indicates larger inclusions that are clearly evident when magnified by ten, and may be seen by naked eye; I2 and I3 indicate presence of inclusions visible to the naked eye and may affect brilliance; I3 is rarely used for jewelry

While such a range of gradations may be confusing to the consumer, they should keep in mind that even slightly included diamonds can appear flawless to the naked eye, and represent substantial savings compared to those with greater clarity. Therefore, deciding which clarity level is right depends largely on one's budget.

One Carat Diamond Earring Styles

Diamond earrings are available in a number of different styles to suit various occasions and personal fashion senses. The most common styles are studs, clusters, hoops, and various other dangling styles.

Diamond Stud Earrings

Diamond studs are perhaps the most ubiquitous form of diamond earrings. Featuring one or more diamonds in a simple setting that holds the stones at the centre of the earlobe. Studs are available in a number of sizes, including one carat.

Diamond Cluster Earrings

Diamond cluster earrings feature a cluster of small diamonds, and possibly other gems. They may be studs or dangling earrings. The effect of several small stones set in various designs has a striking effect, perfect for fancy occasions.

Diamond Hoop Earrings

Diamond hoop earrings feature several small diamonds set into a metal hoop that hangs from the earlobe. Hoops come in different sizes; small huggies are better for professional situations, while larger ones are perfect for dressy evenings out. Hoops also come in different variations, including ovals and hearts.

Diamond Chandelier Earrings

With their intricate designs and tiered, dangling structure, diamond chandelier earrings create a dramatic impact. These are an excellent choice for formal occasions.

Other Dangling Diamond Earrings

Dangling diamond earrings hang below the earlobe, sometimes several centimeters, for an extravagant, flattering look. Dangling earrings may feature a single solitaire diamond at the end of a silver or gold earring, or any number of other designs and configurations of smaller stones.

Diamond Certification

Diamond earrings can be an investment, and one way to verify the value of the stones is through an independent certification process. Certified diamonds have been evaluated by one of several internationally recognised organisations: the International Gemological Institute (IGI), the Gemological Institute of America (GIA), or the European Gemological Laboratory (EGL). These institutions are not connected with the buying or sale of the diamond, and provide an unbiased assessment of a diamond's "four C's": cut, clarity, colour, and carat weight.

Buyers should note that in order to be certified, diamonds must be at least 0.25ct each, with a colour rating of G. For colour ratings of H or I, they must be at least 0.30ct.
