Blue Diamond Necklace in Silver, Gold & Titanium – “3 Box”

Michael Jensen turns geometry into something unexpectedly dynamic in "3 Box," a one-of-a-kind blue diamond necklace. Crisp architectural sections stack into a long, linear composition, but the mix of texture, color, and asymmetry keeps it from ever feeling rigid. A vivid blue marquise diamond becomes the focal point, almost suspended within the structure and pulling the eye straight through the center of the design.

The palette is especially striking. Cool blue anodized titanium plays against oxidized sterling silver and rich 22K yellow gold, creating layers of color that seem to shift with the light. Blue appears in both the titanium and the diamond, giving the pendant two distinct sources of color. Rather than relying on traditional gemstone sparkle alone, Jensen lets the surfaces and materials do just as much of the visual work. His background in both sculpture and engineering makes sense here: the pendant feels carefully constructed, but still distinctly artistic.

It's bold without being oversized and unusual without becoming difficult to wear. This feels less like a conventional pendant and more like a small piece of wearable architecture. Wear it at a simple neckline to give the form and contrasting tones room to stand out.

FAQ

Will the color I see on my screen match the necklace in person?
The blue anodized titanium, oxidized silver, yellow gold, and vivid blue diamond can all read a bit differently depending on the light around them, and your monitor adds its own variation on top of that. Screen settings, video cards, and browsers can all affect color slightly, so the necklace you receive may look a bit different than what you see here. By purchasing, you're acknowledging that possibility. If you'd like a true look before buying, we're happy to walk you through it over video chat.

Has the diamond been treated?
Yes. The marquise diamond is disclosed as irradiated, meaning it has undergone irradiation treatment to alter its color. Its blue should not be mistaken for the color of an untreated diamond.

Is the blue area of the pendant also diamond?
No. The blue area of the pendant is anodized titanium, a separate material from the gemstone.
