EXCLUSIVE
It's 59 in Big D, but the forecast calls for ICE -- 215 CARATS worth -- around Dez Bryant's neck ... 'cause the Cowboys superstar ordered $200k worth of RIDICULOUS jewelry.
Bryant hit up Johnny's Custom Jewelry in Houston ... and commissioned a Cuban Link chain and bracelet ... as well as 5 "X" pendants (ya know, Dez throws up the "X").
King Johnny -- the shop's owner -- tells TMZ Sports Dez wanted something unique ... so he designed and fabricated each piece, diamond by diamond ... which took 2 months.
The breakdown: bracelet & chain, 175 carats. The 5 "X" pendants, 40 total carats.
