IGI-Certified 18k Gold Round-Cut Diamond Stud Earrings (3/4 cttw, H-I Color, SI1-SI2 Clarity)

No jewelry wardrobe is complete without a classic pair of diamond stud earrings. Simple enough for daytime wear, yet radiant with evening attire, they offer sophistication and versatility all in one beautiful package. These classic studs, available in 18 karat white or yellow gold, showcase single round-cut diamonds with a total weight of 3/4 carat, held securely in four-prong settings. They are featured on posts with friction-back closures.

These are fine quality diamonds, with exceptional brilliance. They are near-colorless, with a minimum color rating of H-I, and appear white to the eye. The clarity rating of these diamonds is Sl1-2, meaning there are small inclusions that can be seen somewhat easily under 10x magnification. These inclusions are not visible to the unaided eye, however, and the diamonds appear clear in the mounting.

Diamond Clarity: 
No two diamonds are alike. A diamond's most distinguishing characteristics are its inclusions, marks that are often invisible to the naked eye. However, under a jeweler's magnifying loupe or microscope they can look like crystals, tiny rivers, or clouds. A diamond's clarity is determined by the presence or absence of inclusions--fewer inclusions mean better clarity--and how visible they are. The greater a diamond's clarity, the greater its brilliance and value. A diamond categorized as internally flawless will have no inclusions, but this is extremely rare.



Diamond Color:
Though diamonds come in a wide range of colors, colorless diamonds have traditionally been considered the most valuable. Most diamonds are graded on a scale using the letters of the alphabet, from D (colorless), the best grade, through Z (a light yellow). It is difficult for the untrained eye to notice such variations in color unless stones are being compared side by side.




Diamond Carat Weight:
A diamond's weight is measured in carats, with one carat being equivalent to 100 points. You will often see a diamond referred to as a 3/4-carat stone or a 75-point diamond. Larger stones are often more highly valued, but size should not be the only consideration--high brilliance, which varies according to clarity, cut, and color grade, is highly desirable in a diamond.



Diamond Certification:
A diamond certificate represents independent verification that the stone purchased has all the qualities of cut, color, clarity, shape, and weight expected. It is a further indication of the condition and value of that diamond as represented on our site. Such certificates are issued by several agencies employing highly trained gemologists and provide an unbiased and accurate evaluation of the diamond. These gemologists scrutinize each stone to analyze its dimensions, clarity, cut, color, finish, symmetry, and other details.
Diamonds purchased from the Amazon.com Collection may be certified by the Gemological Institute of America or the International Gemological Institute.  The type of certificate provided will be noted in the product specifications of your jewelry purchase; if you do not see a certificate type noted, one will not be provided.

Our Diamond Policy:
Amazon.com sources high-quality diamonds from some of the world's largest suppliers.  All our diamond suppliers certify that to their best knowledge their diamonds are not conflict diamonds.

Diamond Care:
Diamonds, as the hardest substance on earth, are resistant to damage. However, diamond jewelry is set in different metals, and care will vary from piece to piece. Diamonds should be cleaned in a solution of one part ammonia to six parts water, using a gentle scrubbing brush to remove any dirt. It is a good idea to have them cleaned once a year by a professional jeweler, at which time the security of the setting can be checked as well. Diamond jewelry should be stored in a soft cloth pouch to ensure that the stone will not scratch other jewelry.

Gold Purity

The purity of gold is measured in karats. Pure gold measures 24 karats but is too soft in this state to be used effectively in jewelry. So it is alloyed with other metals--silver, copper, nickel, and zinc--to increase its strength and durability. Common measurements once the alloy is added are 18 karat (75% gold), 14 karat (58%), and 10 karat (47.7%). In the United States, the legal karat limit for the metal to still be considered gold is 10 karats. A higher karat measurement in gold content indicates a greater value of the jewelry piece. Gold jewelry should always be stamped with the karat mark, either 18k, 750 (European marking for 18k), 14k, 585 (European marking for 14k), or 10k. In addition, to assure its quality, the piece should be stamped with the manufacturer's trademark or country of origin.

Gold Color

The color of gold may vary based off of the type of metal alloy included and the percentage of the metal alloy used. Most commonly, gold is available in yellow, white and rose coloring.

Yellow gold is the most common color and is usually alloyed with silver and copper. Yellow and white gold are similar in strength and malleability, making them perfect for jewelry that is worn daily.

White gold is alloyed with nickel, copper, and zinc--and while it looks similar to platinum, it has vastly different properties.

Rose-colored gold is alloyed with copper and is often used to accent white or yellow gold. The saturation of color varies from piece to piece and according to gold content.

Caring For Your Gold Jewelry

To keep gold shining and scratch-free, avoid contact with chlorine and other harsh chemicals. Do not wear jewelry during rough work and be sure to store it in a fabric-lined jewelry box or pouch. To clean gold jewelry, use warm water, a mild soap, and a soft bristled brush, if needed.
