Diamond jewellery stood out as the preferred choice for most of the stars attending the American Music Awards, including Carrie Underwood, Jennifer Lopez, Mary J. Blige and Shakira. Long shoulder-grazing drop earrings, a diamond bracelet and ring were worn by Underwood. Lopez wore a 5-carat diamond wraparound ring designed by Ofira, black and colourless diamond geometric circle earrings designed by Lorraine Schwartz, a white gold and diamond encrusted wraparound twisted cuff and dome diamond ball ring. Blige wore Lorraine Schwartz jewels - 30-carat diamond encrusted geometric earrings, a diamond mesh cuff, all worth around $800,000. Shakira wore Ofira's black gold, black and colourless diamond ring and blackened diamond bangles, while Kate Hudson dressed up with Anita Ko's white gold and diamond ring earrings, two white gold and diamond spike bracelets and a white gold pavé band, reports say.

One of the jewellery trends exhibited at the awards was wearing multiple rings on one hand, as did stars like Rihanna wearing Neil Lane's designed two black and colorless diamond and platinum rings with Sutra's rose-cut "3x3" diamond ring. Music artist Jay-Z wore a Martin Katz designed diamond lapel ring and pin. The function also saw some artists adorning gemstones including garnet in platinum, rose amethyst in pink mother-of-pearl.
