The Trion Rhombus Ring is a 4mm titanium band cut with flat rhombus and triangle facets across its face. Each plane catches the light at a slightly different angle, so the ring flashes from many directions as your hand moves. It's geometric, structured and unisex, and it comes in US sizes 6 to 12.
Geometry, not decoration
A plain band reflects light in one smooth arc. The Trion breaks that arc into many angled planes. Each rhombus and triangle reflects light on its own, so the ring shimmers with small, shifting flashes rather than a single shine. There are no stones and no added detail. The surface geometry does all the work.
Made for any hand
At 4mm wide, the Trion has a confident, clearly intentional presence. It's a standard width for men's rings and a bolder, architectural choice for women's. Sizes run from US 6 to 12, from the smaller ring finger through to larger hands. Wear one alone as a single considered ring, or stack it beside smooth bands for contrast.
Built for real life
Titanium handles water, sweat and humidity well, and it won't tarnish. The rhodium plating gives the facets their bright, white finish. Over time it may soften first on the sharp facet edges, because rings take more knocks than any other jewellery. Take it off for heavy lifting or gym work to keep the facets crisp.
Geometric precision. Quiet structural confidence.

A 4mm band fits slightly snugger than a thin ring. If you're between sizes, choose the larger one.
FAQ
What does the faceted surface look like?
The band's face is cut into flat rhombus and triangle planes in a repeating pattern. Each facet catches the light at a different angle, so the ring flashes with small, shifting points of light as your hand moves.
How do I find my ring size?
Measure the inside diameter of a ring that fits you well, and match it to the size guide. Or wrap a strip of paper around your finger, mark where it overlaps, and divide that length by 3.14.
Does a 4mm ring fit differently?
Yes, a little. Wider bands cover more of the finger, so they feel slightly snugger than thin rings. If you're between sizes, choose the larger one.
Is the Trion suitable for men?
Yes. Sizes US 9 to 12 cover most men's ring, middle and index fingers. Its geometric design reads as considered rather than decorative, which suits a single daily ring.
Can I stack the Trion?
Yes. Its angular facets contrast well with smooth plain bands and stone-set rings, making each ring in the stack stand out more.
Can I wear it in the shower?
Yes. Titanium handles water, sweat and heat. Over time, the rhodium plating may soften first on the facet edges, which is normal wear for a faceted ring.
Will the Trion tarnish?
No. Titanium doesn't tarnish the way silver can. To keep the facets crisp and bright, take it off for heavy lifting and gym work.
Is it suitable for sensitive skin?
(To be finalised once the material is confirmed.) If it's pure titanium: "Titanium is one of the most skin-friendly metals, and is well tolerated even by very sensitive skin." If it's titanium steel: "Titanium steel is well tolerated by most people. If your skin is very reactive, MNML's pure titanium pieces are the most reliable choice."
Does it come with packaging?
No. The Trion is part of the Elements collection and ships without a box. A gift box is available separately.
