The Lumo in Blue – UV Glow Stainless Steel Ring
Bold by day, electric by night. The Lumo in Blue is a ring that shifts with the light — a deep sea blue by daylight, transforming into an intense electric blue under UV. With its clean flat profile and glowing centre channel, this ring blends subtle elegance with a spark of something unexpected.
Crafted from marine-grade stainless steel and handmade in the UK, it’s a piece that doesn’t just sit on your hand — it comes alive with you.
Crafted to Endure
Made from premium 316L marine-grade stainless steel, the Lumo ring is built to last. It won’t tarnish, rust, or discolour your skin. Its strength makes it ideal for everyday wear, while its resistance to distortion means it keeps its shape even under pressure.
A Comfortable Fit
The flat band gives the Lumo a modern, structured profile. At the centre, a 1mm groove is hand-filled with high-grade UV glow powder. When charged with sunlight or the included mini UV torch, the pigment comes to life — glowing for up to 12 hours after activation.
Handmade Just for You
Each Lumo ring is handcrafted in our workshop and can be engraved inside with your own message, date, or name. The Blue version featured here transitions from a rich ocean tone to a vivid electric blue — but other colour options are also available:
– Sunset: Fuchsia by day, peach glow under UV
– Lime: Deep teal green that glows neon green
– Zing: Lemon yellow that transforms into vivid neon yellow
The True North Promise
We include a complimentary ring sizer and free UK shipping with every order. Your ring also comes with a small UV torch to keep the glow going, wherever you are. If you need help choosing your colour or size, we’re here to guide you.
