Since ancient times, the Romans have loved the four-petaled flower that symbolizes happiness and joy, so Bob has drawn inspiration from this beautiful flower that blooms in the Eternal City to design Quatuor jewelry. Bob diamonds bloom into a breath-taking four-petal flower. The diamonds are specially cut to form delicate petals. This spiral ring reinterprets the beauty of nature with a luxurious and gorgeous light.

Made from GR4 jewelry-grade titanium steel — the high-toughness tier of our five-grade system, built for structured pieces that keep their shape. 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 0.4 µm PVD thick gold plating, so it keeps its colour instead of fading or oxidising.

LOTTEDS Bob Quatuor Collection — Four-petal flower jewellery
The Quatuor Collection

Where Luck Blossoms

Four petals, one perfect symmetry. The Bob Quatuor Collection reimagines the quatrefoil — the four-leaf clover of Gothic architecture and royal gardens — as modern jewellery.

Quatuor collection craftsmanship detail

Symmetry You Can See

Four equal leaves, matched by hand so the shape stays true when you look straight at it. Every corner is rounded and polished smooth.

Nothing catches on knitwear, and nothing scratches when you stack two together for a wider band.

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 the gold colour fade, oxidise or turn my skin green?
The colour is a 0.3–0.5 micron PVD gold finish bonded into the surface, not a dipped coating, so it resists fading and keeps its tone with normal wear. A green mark on the skin comes from copper — our titanium steel is copper-free, and the higher the grade the more inert the metal. Perfume, chlorine and abrasive contact are what shorten any plated finish, so put jewellery on last and take it off first.
Is it safe for sensitive skin, and can I wear it in water?
Yes to both. The base is jewelry-grade titanium steel — the material family specified for surgical instruments and implants, copper-free and nickel-controlled — and the finish means skin never sits on reactive metal. It is waterproof and sweat-proof, so showers, workouts and travel are fine; just rinse and dry after chlorine or salt water.
Are the stones real?
Our centre stones are lab-grown diamonds and lab-grown gemstones, with hand-set brilliant-cut diamond pavé set by hand at VVS clarity. Named stones such as malachite, mother-of-pearl and turquoise are selected for colour and quality. Nothing is a simulated stone pretending to be something else.
What if it does not fit or I change my mind?
Contact us within the return window set out in our Refund Policy and we will send the instructions and return address. We also help with sizing by email before you order — send us your measurement and we will tell you which size to take.
Which titanium grade is this piece, and why?
Every piece carries exactly one grade, shown on its product page, in the highlights and in the description. The scale only runs one way: GR2 is the purest and softest, and each step up in number adds toughness, corrosion resistance and resistance to oxidation. Light pieces worn close to the skin use the lower grades; bracelets, cuffs and rings that must hold their shape move up; the top grades are reserved for our most demanding designs and price levels.
How long does shipping take, and how do I track it?
Orders are packed and handed to the carrier quickly, and delivery time depends on your destination — current processing windows, rates and delivery estimates are listed in full on our Shipping Policy page. Every parcel ships with tracking and the link is emailed as soon as it leaves us. If tracking stalls for several days, message us and we will chase the carrier.
