The Bob Aura Convex Dome Ring, Sapphire is built around light. An interplay of interlocking links and a full pavé of Sapphire, lab-grown diamond creates a continuous halo of brilliance that moves with the wearer and lifts even the simplest outfit.

Made from GR5 jewelry-grade titanium steel — the aerospace-grade tier of our five-grade system, with the best strength-to-weight in the family. 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 0.5 µm PVD thick gold plating, so it keeps its colour instead of fading or oxidising.

LOTTEDS Bob Aura Collection — Convex dome jewellery
The Radiance Collection

Wear Your Own Light

The convex dome — a perfect, glowing hemisphere — is the soul of the Bob Aura Collection. Minimal, architectural, and luminous from every angle.

Aura collection craftsmanship detail

Sized So the Stone Sits Right

The centre stone is matched to the band width, so it stands on the hand instead of tipping forward. The stones around it are set by hand at an even height.

Nothing catches on sleeves. Choose titanium for lightness or steel for weight.

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.
