I'm already disqualified from rule #1, but I'll enter anyways because I love SM and Mene! Mene sells pure 24 karat gold and platinum jewelry priced transparently by gram weight. This is unheard of in the Western culture as there is a widespread myth that 24K is "too soft" for daily wear. Also, the actual jewelry weight is almost always hidden by other sellers- so you never know how much precious metal content you're actually getting. Mene smashes all these things with its innovative, honest and efficient business model.

@goldmatters and I used to showcase Mene jewelry battles to demonstrate just how much value you get: https://steemit.com/mene/@goldmatters/mene-pure-gold-vs-75-not-gold-challenger-gold-jewelry-battle

My favorite piece (and newly acquired) is the gold narrow groove ring. At 15 grams of solid gold this beauty packs a punch. And the infamous LOD loves it :)
