投资界获悉，近日广东潮宏基实业股份有限公司（简称"潮宏基"）向港交所递交上市申请，拟冲刺"A+H"上市，中信证券为独家保荐人。 这是国内最早的珠宝品牌之一。1997年，潮汕父子廖木枝、廖创宾创立潮宏基，从百货商场的自营小金店转型，一路成长为超1500家门店的知名连锁品 牌，于2010年在深交所上市。如今"A+H"盛行，潮宏基也奔向了港股。 港交所正在掀起一股"黄金潮"——老铺黄金股价大涨，上市不到1年市值翻20倍；不久前周六福登陆港交所，总市值突破200亿港元。而在港交所门外，还 排着一支队伍。 潮汕父子卖黄金，要IPO了 在汕头潮阳，廖创宾所在的村子几乎都以黄金加工为生。1972年出生，廖创宾16岁辍学后便随父亲在外闯荡，不到20岁就加入了父亲廖木枝的黄金代工生 意。 和村子里其他人一样，廖木枝很早就干起了黄金代工的活，前期收购黄金，后委托加工再转卖，赚取部分利润。但到了1993年前后，广州、深圳等地出现 一批港资、台资黄金加工企业，潮汕地区的加工作坊逐渐失去竞争力。 廖氏父子决定转型。他们承包了汕头工艺集团的黄金首饰加工车间，再招揽大量工人，把目光放在珠宝与K金首饰设计上。K金是黄金与其他金属熔合而 成的 ...
