Did Helzberg jewelry carry Carl arts costume jewelry?

Helzberg Diamonds primarily focuses on fine jewelry and diamonds rather than costume jewelry. Carl Art, known for its high-quality costume jewelry, is not typically associated with Helzberg's offerings. While Helzberg may have carried a variety of jewelry brands, it is unlikely they featured Carl Art's costume pieces as part of their main inventory. For specific historical product lines, checking Helzberg's archives or contacting them directly would provide the most accurate information.
