Find Your Dream Engagement Ring

There’s no such thing as one-size-fits-all bridal jewelry. That’s why we provide every person who steps foot into our warm, welcoming jewelry showroom with customized service. We cater each part of the wedding ring shopping process to your needs.  As we discuss what you’re searching for in a ring, present you with options from our expansive selection of designs, and sort through your center stone options, we remain laser focused on making sure your ring has every quality you’ve been dreaming of. 

Create a Custom Design

We offer two types of custom engagement ring design at Diamond & Design. We can create an entirely new engagement ring from scratch or customize an existing design. For example, say you found a ring you like in our showroom, but some of the ring’s details aren’t quite right for you. We can adjust that ring’s design in order to create the exact ring you want. We can make a white gold ring in rose gold, add diamond side stones to a solitaire ring, adjust a ring’s proportions, and so on.

Hand Selected Diamonds in Ontario

Since our primary focus is bridal jewelry, we always have an excellent selection of loose diamonds in our showroom. We hand select every diamond within our collection in order to ensure we offer our customers the most beautiful certified diamonds. If you’re on the hunt for a center stone for your diamond engagement ring, visit our showroom and find out why hand-selecting diamonds is so important. 

Fine Jewelry at Diamond & Design

Alongside carrying the best selection of engagement rings and wedding bands in the Inland Empire, we offer an expansive selection of fine jewelry and fashion jewelry. Stop by and pick up a classic piece, like solitaire diamond stud earrings, a birthstone pendant necklace, yellow gold hoop earrings, a delicate promise ring, or a diamond anniversary ring. Or, discover unique designs that feature alternative metals or striking gemstones like alexandrite, morganite, and tsavorite. If you’re shopping on a budget, we also have a gorgeous range of affordable jewelry, including lab-grown gemstone jewelry, simulated diamond jewelry, and sterling silver jewelry. Whether you’re searching for a gift or something special for yourself, you’ll find a piece you adore in our selection.
