The most common hallmark stamps for 18 karat gold are 18K or 750 that indicate 75% gold purity. 18k yellow gold is an alloy made up of 75% pure gold and 25% alloy (12.5% copper, 12.5% silver).
Aquamarine, like emerald, is a variety of a mineral called beryl. Aquamarine is a blue or cyan variety of beryl and occurs at most localities which yield ordinary beryl. Aquamarine is most often light in tone and ranges from greenish blue to blue-green. The color is usually more intense in larger stones, and darker blue stones are very valuable. The serenely colored aquamarine invokes the tranquility of its namesake, the sea. In fact, the name “aquamarine” is derived from the Latin word aqua, meaning water, and marina, meaning the sea. This gemstone is mined mainly in Brazil, but it is also found in Nigeria, Madagascar, Zambia, Pakistan, and Mozambique. The ancient Romans believed that aquamarine would protect against any dangers while travelling at sea, and that it provided energy and cured laziness. Large gemstones have been found all over the world, including one gemstone found in Brazil that weighed over 240 pounds. Aquamarine grows in large, six-sided crystals that can be up to a foot long. This makes it a great gemstone to be cut and polished in larger carats for bold statement jewelry pieces. Not only is aquamarine one of the March birthstones, it’s also used to celebrate 19th wedding anniversaries. It’s a beautiful gemstone with little or no yellow in it, so it looks great in many settings with different colored metals and gemstones.
Diamonds are a form of the element carbon with a crystal structure. Diamond's great hardness relative to other materials has been known since antiquity, and is the source of its name derived from the ancient Greek ἀδάμας that means "unbreakable". Diamonds are the hardest natural substance on earth and rate a 10 on the Mohs Hardness Scale. Diamond is also known as April's birthstone. They are thought to be first recognized and mined in India many centuries ago. Four characteristics, known informally as the "Four Cs", are now commonly used as the basic descriptors of diamonds: Carat, Clarity, Color and Cut. This system was developed by GIA (Gemological Institute of America), one of the major gemological associations internationally recognized to evaluate diamond characteristics. The carat weight measures the mass of a diamond and the clarity is a measure of internal defects of a diamond called inclusions. GIA’s D-to-Z diamond color-grading system measures the degree of colorlessness: the finest quality as per color grading is totally colorless, which is graded as D color diamond across the globe, meaning it is absolutely free from any color. Last, the cut of a diamond describes the quality of workmanship and the angles to which a diamond is cut.
