Diamond Design

Since 2005, Diamond Design has established itself as a family-owned and operated full-service jewelry store serving the Chino Hills community. Our commitment to personalized service and high-quality craftsmanship has earned us recognition as the #1 Independent Jeweler in the Inland Empire for three consecutive years and the top jeweler in Chino/Chino Hills for five years. We specialize in bridal jewelry and custom designs, working exclusively with U.S.-based designers to ensure exceptional workmanship and unique pieces that reflect individual styles. Our non-commissioned sales team prioritizes long-term client relationships over transactional interactions, fostering trust and satisfaction. With over 25 years of international diamond expertise, we hand-select diamonds based on visual excellence rather than certificate metrics, guaranteeing superior sparkle and value.

Our dedication extends beyond commercewe actively support local schools, charities, and community events through donations and partnerships. As a neighborhood jeweler, we maintain seven-day-a-week availability while preserving the boutique-level attention that distinguishes us from corporate chains. Our philosophy combines traditional service values with modern design sensibilities, creating a welcoming environment where customers feel valued rather than pressured. Through meticulous curation of collections and emphasis on ethical sourcing, we ensure every purchase represents both personal significance and enduring quality.
