Diamond & Design Showroom
Our Mission
To provide our customers the highest quality jewelry in a local, neighborhood setting with the focus on excellent, personalized service.

We pride ourselves in working with U.S. designers, which allows for every feature, facet and workmanship of our jewelry to maintain the highest standards.
Our Team
Our committed sales team is non-commissioned, which supports our desire to foster long-term client relationships and offer unique and personalized service.

We are grateful to the fantastic customers who walk through our doors each day! They are the reason we have been voted the #1 Independent Jeweler in the Inland Empire for 3 years straight and #1 in Chino/Chino Hills for the past 5 years.

Your Trusted Neighborhood Jeweler
We take immense pride in being a family-owned and operated full-service jewelry store. We opened our doors to the Chino/Chino Hills community in 2005 and are humbled by the incredible client and community support we have received. Our business is customer-focused and run by our friendly and trusted staff, led by Certified Diamontologist Homeira Ghassemi and GIA Certified Diamontologist Atila Ghassemi. 

Because we desire to give our clients the most personalized and attentive services possible, we are thrilled to be open 7 days a week. And as a part of the local community, we have enjoyed the opportunities afforded us to give back to various local organizations through numerous donations and events. We’ve been in over 300 events for schools, churches, charities, and fundraisers in our local community. We truly feel that we can make a difference and it is by doing our best for ourselves and those of us around us. We are real people, not motivated by a corporate structure or shareholders.

We truly strive to be the “one stop shop” all the while doing it in a relaxed, fun, and inviting atmosphere. The level of service only found at only the highest end boutiques is now being brought to you without the stuffiness, price tags, or expectations. Family friendly and heavily invested in our local community, we are bridging the gap between high end boutique jewelers and corporate chain stores. Focusing on offering a fair value for a high quality jewelry and service, we are carving out a niche that is uniquely Diamond & Design.

Our Service
The Diamond & Design experience is bringing the old school level of service that has been lost. We hold our clients with the highest level of regard, with our prime focus being to deliver value and a positive EXPERIENCE… we understand that we are building a long term relationship! We want to be your jeweler for life, for any other future needs, and to build a real and genuine connection with those who walk into our store. We are bringing back that old school level of service and realness that has been lost in most businesses today.
Curated Collections
The collections we carry have been carefully selected from different USA based designers with a focus on unique and striking designs. A majority of the jewelry we carry is stocked only once, ensuring our clients jewelry is as unique as they are. Jewelry you will only find visiting the highest end boutiques – just without the tags. Not only are our jewelry pieces hand select, so are our diamonds.
