Kendall Jenner, Bella Hadid, Jennifer Lopez and Demi Lovato were just a few of the many celebrities to accessorize with big hoop earrings in 2017 – and that makes it a popular jewelry trend for 2018. Over the last half century, hoop earrings have popped in and out of style, with their biggest moment in the 1960s and early 1970s. But the style is far older: It was in vogue as long ago as 2500 BCE among Sumerian women, as well as in ancient Greece and Rome. Hoops even dangled from the earlobes of pirates. Now the look is back in a BIG way – meaning jumbo-size hoops.
"Diamond"
Diamonds, rarity equals value. With diamonds in the normal range, value is based on the absence of color, because colorless diamonds are the rarest. With fancy color diamonds—the ones outside the normal color range—the rarest and most valuable colors are saturated pinks, blues, and greens. In all cases, even very slight color differences can have a big impact on value .Diamonds with red or reddish colors are extremely rare and highly valued. Pure pinks are more popular than diamonds that are purplish, orangy, brownish, or grayish. Trade professionals market some very attractive stones in this category as “rose-colored,” and some stones with purplish tints as “mauve” diamonds.Blue diamonds are extremely rare. They generally have a slight hint of gray, so they’re rarely as highly saturated as blue sapphires. Their color is caused by the presence of boron impurities—the more boron, the deeper the blue , Fancy green diamonds are typically light in tone and low in saturation. Their color often appears muted, with a grayish or brownish cast. The hue is generally in the yellowish green category. In most green diamonds, the hue is confined to the surface, and rarely extends through the entire stone. That’s why cutters try to leave as much of the natural rough around the girdle as possible.Green diamonds get their color when radiation displaces carbon atoms from their normal positions in the crystal structure. This can happen naturally when diamond deposits lie near radioactive rocks, or artificially as a result of treatment by irradiation.
"Gemstone"
Ruby, Emerald, Sapphire (also fancy coloured sapphires), Padparadscha sapphire, Rubellite, Spinel (red-pink), Aquamarine, Morganite, Isavorite and mandarin garnet Tanzanite. Quality is the major part and covers the main visual characteristics of the gemstone, consisting of colour, clarity and transparency as well as cut and brilliance.Rarity considers the relative availability of this type of gemstone in the market. It includes the gemstone variety, its size and the absence, presence and severity of treatment. Salience addresses the extent of exceptionality and attractiveness of a gemstone beyond the objective characteristics of the quality category. It is best seen as the gemstone’s capability to stick out of the crowd.
