Your Ideal Partner for Diamonds, Gemstones, and Custom Jewelry Design -

K. Rosengart

K. Rosengart's 28+ years of experience in jewelry design and manufacturing, bench work, and stone setting makes us an ideal partner for designers and manufacturers looking for high-quality standards and attentive, personalized support. We are known for providing the finest diamond melee, but we also provide loose diamonds and gemstones in various shapes, sizes, and colors. In addition, we offer diamond cutting, sorting, bagging, testing, setting, and polishing services. Everyday consumers and jewelry stores looking to expand their service offerings often turn to us for our custom jewelry design services. At K Rosengart, we pride ourselves on the quality of our stones and designs. But of equal — or even greater — importance is our ongoing commitment to outstanding service. Our staff is as friendly as they are knowledgeable, as helpful as they are experienced. This caring and competence is coupled with prompt delivery and competitive prices. Not all diamonds are cut with equal precision and skill; and not all diamond supplier services offer the same quality and consistency. Demand the finest melee and impeccable service. And receive it with every order, with every stone. K. Rosengart: we are your dedicated diamond specialists.
