Want to win free diamonds? This is a good week to try. There are a flurry of social media campaigns taking place online from diamond jewelry makers and retailers looking to draw in new customers by giving away rocks to those who enter contests on Facebook fan pages.

AnaKatarina Eco Gioielli and Canada Goose: Win a socially responsible, ethically mined diamond bezel-set in an 18k white gold pendant. Valued at $2,500, the 0.60 ct. diamond is F color, SI2 in clarity, with no fluorescence.

Steve Padis Jewelry, San Francisco, and Passion Cut Diamond by ADR Kropveld: Win either a pair of 0.50 ct. Passion Cut Diamond halo-style earrings, or a 0.50 ct. Passion Cut Diamond halo-style pendant on a 16-inch chain. Made in 14k gold, both pieces are valued at $1,200. In its Passion Cut Diamond Giveaway, the dealer is partnering with three different retailers nationwide this fall in order to drive awareness to its 81-facet stone.

Northeastern Fine Jewelry in Albany, N.Y., hosted the first giveaway last month, and Johnson Jewelers in El Paso, Texas, will be responsible for next month’s giveaway.
