About Cornerstone Service
Cornerstone has been owned and operated by Wesley & Beth Grau since 1983. Wesley started in business as an independent service provider of watches, clocks, and jewelry to the retail jewelry industry in 1982 then in 1983 he and his wife Beth purchased their own retail establishment which was named Cornerstone Jewelry. They continued to provide service to other retail jewelry businesses under the name Cornerstone Service Center as well as work directly with retail clients of their own, expanding their service to include jewelry manufacturing and repair. They closed their retail store in 2003 to take positions establishing a service department for a luxury watch dealer. In 2011 they decided to return as an independent service provider to both retail jewelers and private clients.
Committed to helping our customers stay on time.
