Bold yet polished, the Bob Rollers Marlo Band Ring, Three-Tone Gold, Plain, High Polish takes its cue from the sculptural rhythm of rolling forms — smooth ceramic and metal volumes that catch the light as the body moves, pairing clean geometry with a modern, confident silhouette.

Made from GR3 jewelry-grade titanium steel — the balanced tier of our five-grade system, matched for everyday wear. It carries the look and the weight of fine jewellery without the heft, never rusts, and it contains no copper and no allergenic heavy metals, so it will never turn your skin green. Finished with 0.3 µm PVD thick gold plating, so it keeps its colour instead of fading or oxidising.

LOTTEDS Bob Rollers Collection — Precision-engineered jewellery
The Precision Collection

Engineered to Move With You

Rolling gears, fluid mechanisms and architectural lines — the Bob Rollers Collection brings precision engineering to fine jewellery.

Rollers collection craftsmanship detail

Light Enough to Forget You're Wearing It

Solid titanium — the metal used in aircraft and medical implants — so a full band weighs about half what a silver one does and never rusts in sweat or seawater.

The gold is bonded into the metal three to five times thicker than typical plated jewellery, so it keeps its colour instead of fading or going dull. Open cuffs adjust one size up or down, so it fits right the first time.

"Precision is not cold — it is the highest form of elegance, engineered to move with you."LOTTEDS Bob Rollers Collection

✦

GR2–GR6 Jewelry-Grade Titanium Steel

Our titanium steel is graded GR2 to GR6 — the same material family trusted for surgical instruments and aerospace parts, tuned here for jewelry. Each piece is matched to the grade its design and price call for.

❖

925 Sterling Silver

Solid 925 sterling silver, finished with heavy 0.3–0.5 micron PVD gold. Hard-wearing and colour-sealed, it resists tarnish and never turns black with daily wear.

◈

0.3–0.5 µm PVD Thick Gold Plating

Colour comes from PVD thick gold plating, not from the base metal — 0.3 to 0.5 micron, and the higher the number the longer it keeps its tone. 14K and 18K gold plating available on selected pieces.

Questions, Answered

Everything you need to know
Will it tarnish, fade or turn my skin green?
No — the colour is sealed in with 0.3–0.5 micron PVD thick gold plating over a solid metal core, so it resists fading, oxidation and any green mark on the skin. Store it in the pouch and keep perfume, lotions and chlorinated water off it, and it keeps its colour for years.
Is it safe for sensitive skin?
Yes. Our pieces are made from jewelry-grade titanium steel graded GR2 to GR6, plus solid 925 sterling silver on selected designs — no copper, no lead, no cadmium and nothing that commonly triggers a reaction. Titanium steel is the same material family used for surgical instruments and medical implants, so safety is not the question; the grades simply tell you how tough and corrosion-resistant each piece is.
Are the stones real?
Our centre stones are lab-grown diamonds and lab-grown gemstones; named stones such as malachite, mother-of-pearl and turquoise keep their own character. All accent stones are Lab-grown diamond at VVS clarity — the same fire as mined stones, without the mining.
What if it doesn't fit or I change my mind?
You have 30 days to return it for a full refund — no questions asked. We also offer a 2-year defect warranty and free resizing advice by email.
