One way to dress up a clean-cut look: Throw on dozens of diamonds. Everyday outfits, which these days may consist of sporty tees and chic sweaters, can transform into statement ensembles when styled with a few pieces of gem-laden jewelry—in this case including rare pieces from the season’s sought-after high jewelry collections. Though it may seem out of place to wear big stones with casual clothes, stylist Elizabeth Fraser-Bell demonstrates the trick is to consider the neckline, the sleeve length and the color of each garment. In some cases, the jewelry can fit in like a puzzle piece. A double-layer V-shaped necklace from Graff made of 11 carats of diamonds and 17 carats of emeralds falls effortlessly inside the lines of an unbuttoned shirt, while the round crew neck of a T-shirt frames a Bulgari Serpenti choker. 

“Don’t be afraid to go big and clash,” says Fraser-Bell, who, for this shoot with photographer David Abrahams, played with the idea of preppy dressing mixed with extra-large precious pieces. A white turtleneck and beige cardigan provides a neutral backdrop to pile on Dior’s Rose des Vents emerald and diamond layered necklace with a pair of large ball hoops and a diamond starburst ring from David Yurman. The curve of a white-gold-and-diamond Pluie de Cartier High Jewelry necklace plays off the slouchy V-neck of a cable-knit sweater. A crisp black-and-white houndstooth blazer worn with Tiffany’s gold-winged pearl earrings and Van Cleef & Arpels’s onyx and mother-of-pearl pins looks ultra modern. Lastly, if you prefer simplicity, a lone pair of diamond earrings is always a good solution. A sleek style, such as Louis Vuitton’s La Cavalière diamond-and-white-gold earrings, go well with just about anything, including bare summer skin.  —Jenny Hartman
