After doing business for over 30 years, as Bernie Helmick's Diamonds and Gold, and a successful re-branding, here at CDI we strive to make each and every one of our loyal customers experience unique, personal, and private. With our location in an office setting we are able to not only ensure an experience unlike any other, we also offer pricing significantly lower than any competitor accompanied by higher quality all due to our low overhead environment. We have our own in house Graduate Gemologist that does insurance appraisals on the spot. At CDI we have a combined 60 years total experience, not only in retail, but also in wholesale, independent engagement ring line design and manufacturing, and attendance for over 30 years of both domestic and international industry trade shows.
