Training- G.I.A. As a Graduate Gemologist, I have been a part of Van Horne Jewelers since I was old enough not to be underfoot, which adds up to over 40 years. My father, Madison Knight Sr., and I are co-owners of the store. In addition to the extensive G.I.A. training received, I’ve basically been a part of every operation of the store. From being a goldsmith, to traveling to buy diamonds, I’ve done it all. I enjoy the challenges of the retail business and especially like having a part in some of the happiest moments in our customers’ lives. Most recently, I’ve designed a custom jewelry database, Guild Jeweler, and have implemented it at my store and in 50 other stores around the country. It is through this comprehensive software suite that we are able to effectively manage our many customers and the complex aspects of owning/managing a premier jewelry store.
