Playing on the contrast between black and white, and influenced by the shape of the club on playing cards, this bold and distinctive collection mixes silver & black faceted onyx. Originally called 'twenty-one', when Blackjack was introduced in the United States, gambling houses offered bonus payouts to stimulate players' interest. One such bonus was a ten-to-one payout if the player's hand consisted of the ace of spades and a black jack (either the jack of clubs or the jack of spades). This hand was called a "blackjack", and the name stuck to the game even though the ten-to-one bonus was soon withdrawn.

Elegant glistening black onyx mixes strikingly with silver to create a winning combination.
