If you’re ready to begin the custom design process, or if you just want to get a feel for how it all works, you can visit our Bellevue, WA or Seattle, WA showroom in person or reach out to us through our website. We’ll walk you through exactly what to expect at every step along the way, and we’ll use all of the technological tools at our disposal to ensure that you can visualize and approve every detail of your design before we ever cast anything in metal.
Diamond Solitaire
The only gemstone in this ring is a large trillion diamond. Trillions are triangle shaped with equilateral sides. The diamond is cradled in three prongs made of 18k yellow gold. They are rounded and gracefully flow down into the setting to meet at the base. Diamond Engagement Rings
The head of the ring holds the center diamond, and the prongs meet to attach to the band, while a semi-cathedral arch rises up from the band to connect with the basket and supports that allow the center diamond to be safely held in the ring. It is considered a low profile setting.
Customization Options
If you're interested in customizing this ring, you could begin by choosing a different type of metal. Platinum or white gold would give this ring an immediate icy look with the sharp angles of the trillion. In contrast, rose gold would add even more contrast to the diamond. To add a bit more sparkle, you could add pave diamonds to the basket bars below the diamond.

Customizing This Design
Any Joseph Jewelry item can be customized or used as the starting point for a new custom design. The gemstones, metal, proportions, setting style, surface details, and overall profile can be adjusted to better match your preferences, style, and budget.
Every custom piece begins with a conversation about what you want to create and what matters most to you. You work one-on-one with a designer to refine the concept, review the design direction, and create a detailed 3D CAD image of the item before it is made.
After the design is approved, we can create a wax model so you can review the piece physically. This step helps you evaluate scale, proportions, shape, and overall presence before final production begins.
Once the wax model is approved, our jewelers craft the finished piece with attention to structure, finish, stone security, and long-term wear. Each adjustment is reviewed carefully so the final item feels intentional, balanced, and made specifically for you.
You do not need to have every detail figured out before starting. If you like this item but want to change the stone, metal, size, shape, width, engraving, or overall style, we can guide those decisions through the custom design process.
Quality & Craftsmanship
At Joseph Jewelry, quality begins with the structure. We follow strict design and construction standards for metal thickness, weight, stone support, setting security, and long-term durability. These details help ensure the item is substantial enough for everyday wear while still maintaining a refined appearance.
We do not design custom jewelry to be unnecessarily thin or fragile. If a setting, band, gallery, or accent detail needs more support, we address it before production begins. The goal is to protect the stones, preserve the shape of the ring, and create a piece that can be worn confidently over time.
Gemstone selection is also part of our quality process. We help choose the center stone, side stones, and melee diamonds used in each ring, reviewing them for cut, color, clarity, consistency, and how well they fit the design. Even when a ring is designed around a specific budget, we maintain careful standards for the materials and craftsmanship that determine the quality of the finished piece.
Before completion, each custom piece is reviewed for proportion, comfort, stone security, finishing, and long-term wear.
Care & Warranty
All Joseph Jewelry custom pieces are supported by our lifetime warranty. We also provide long-term care, including complimentary cleaning and regular inspection, so your jewelry can be maintained properly over time.
Routine inspection is especially valuable for pieces worn every day. It allows the setting, stones, and overall structure to be checked as the jewelry is worn.
