LELRA | Black Tungsten Blue Groove Blue Anodized Interior Beveled Wedding Ring — 8mm
The LELRA is a handcrafted black tungsten carbide men's wedding band, 8mm wide, with a brushed black tungsten body, a single recessed deep-blue center groove, and a deep-blue anodized aluminum interior sleeve visible on the inside of the band. Built comfort-fit, inside-laser-engravable, and backed by our lifetime warranty — a wedding band where black exterior hides a pop of blue on the inside.
The Metal
Tungsten carbide is the hardest wedding-band metal made — roughly 4× harder than titanium and 10× harder than 18k gold. That's not marketing language; it's a measurable Mohs hardness of 8.5–9. In practical terms: this band will not scratch from keys, tools, gym equipment, or daily contact with desks, steering wheels, or phone cases. It will look the same in five years as it looks the day you open the box.
The black exterior tone is a PVD (physical vapor deposition) finish bonded to the tungsten core at the molecular level — not paint or plating. It won't peel, strip, or wear through. The blue groove is PVD-filled at the same molecular level. The blue interior sleeve is anodized aluminum — a hard oxide coating that locks the color into the metal. The metal is fully hypoallergenic and nickel-free. The beveled profile chamfers the outer edges.
The Blue Groove with Blue Anodized Interior
The LELRA is a hidden-color wedding band. From the outside the ring reads mostly black: brushed black face, polished black beveled edges, with one deep-blue groove line splitting the center. Turn the ring inward and the inside of the band reveals a full deep-blue anodized aluminum sleeve — a bright flash of sapphire color lining the interior where only the wearer sees it most of the time.
That interior color is the story. Anodized aluminum creates a hard oxide layer with color locked into the metal surface itself, not painted on. It's a technique borrowed from aerospace and performance hardware — durable, scratch-resistant, and vivid. The outside keeps the ring grounded in masculine black; the inside rewards the wearer with something personal only they know is there.
Who It's For
The LELRA is for the man who likes a secret in his everyday objects — a blacked-out exterior anyone can see, with a vivid blue interior only he notices every time he takes the ring off. If you wear technical hardware (performance watches, precision tools) or simply love the concept of hidden color, this is the band.

Care Instructions
Clean with warm water, a drop of mild dish soap, and a soft cloth — the anodized aluminum interior is fully water-safe. Dry thoroughly. Avoid strong alkaline or acidic cleaners (bleach, oven cleaner, acetone) which can over years etch anodized finishes. For polished black tungsten exterior, a microfiber cloth buffs out fingerprints. The blue interior stays vivid for the life of the ring with normal care.

Frequently Asked Questions
Q: What is the blue interior made of? A: Anodized aluminum — a hard oxide-coated aluminum sleeve with the color chemically locked into the metal surface. It's durable, scratch-resistant, hypoallergenic, and holds the sapphire-blue color indefinitely.
Q: Does the blue interior stay blue forever? A: Yes. Anodizing isn't paint — it's a color-embedded oxide layer that's part of the aluminum surface itself. It won't wear off, fade, or peel under normal daily contact.
Q: Can I engrave the LELRA? A: Yes. Free inside laser engraving is included — up to 30 characters, any font. Engraving is laser-cut into the anodized interior and appears as a bright line against the blue.
Q: Will tungsten scratch from daily wear? A: No. Tungsten carbide is rated 8.5–9 on the Mohs hardness scale — roughly 4× harder than titanium and 10× harder than 18k gold. Keys, tools, gym weights, steering wheels, and daily contact will not scratch the surface. After ten years of wear, it will look the same as the day you unboxed it.
Q: Can this ring be resized? A: No — tungsten is too hard to bend or stretch. Instead, we include a replacement sizing program: if your finger size changes within the lifetime of the ring, send the ring back and we'll replace it with the new size for a small handling fee. The ring itself will never deform on your finger.
Q: What's the warranty? A: Lifetime warranty on defects plus lifetime replacement sizing — the two things that matter on a wedding band you wear every day. If the ring breaks, cracks, or fails under normal wear, we replace it. If your finger size changes, we replace it in the new size.
Every ring you purchase from us includes a lifetime warranty and lifetime resizing. We make our jewelry with great care, using top-quality materials and skilled craftsmanship. We guarantee that our products are free from defects. If, by any chance, a piece of jewelry doesn't meet our high standards, we will replace it under our warranty.
