Breaking into the crowded flash-sale site industry is a daunting task. Therefore, GemLust knew it needed to do something to generate some positive word-of-mouth. The private online jewelry retailer in the mold of Gilt Groupe (members have to be invited to join the community) launched a promotion in late August where members were given a $100 credit to the site when they invited a friend to join the GemLust community and that friend made 
a purchase.
