Shop best sellersOne family workshop in Surat. Delivered across Manchester, duty-paid.
Every Signora piece is made to order in our family workshop in Surat — the city that cuts and polishes most of the world’s diamonds — and delivered to any Manchester address with duties and import taxes settled before dispatch. No middlemen, no showroom markup.
On 22 October 2004, physicists at the University of Manchester published the first unambiguous isolation of graphene — carbon in a sheet one atom thick — lifted from ordinary graphite with adhesive tape. In 2010 Andre Geim and Konstantin Novoselov received the Nobel Prize in Physics for those experiments. A diamond is that same element. Nothing else about it is different.
The hardest material we know and the thinnest one are both simply carbon.
What separates them is arrangement. In a diamond every carbon atom is locked to four others in a rigid three-dimensional lattice; in graphene they lie in flat hexagonal sheets. Himmat Mangukiya, our founder, is the third generation of a Surat family in the diamond trade — he joined at nineteen, in the city that cuts and polishes the overwhelming majority of the world’s diamonds. Every stone we set is carbon in the first arrangement, grown, cut and set to order, reaching Manchester in about fourteen days with duties already paid.
Below: how it reaches you, and what it costs when it lands.
Signora Jewels is an independent jeweller. It is not affiliated with, endorsed by, or a member of any organisation named above; the history here is offered as context only.
Our workshop is in Surat, and it stays in Surat — that’s where the craft is. But our UK client-care team works from the West Midlands — a phone call away from Manchester, in your time zone — so there’s someone to reach before you order and after your piece arrives. Ask us anything: sizing, stone specs, delivery dates, or whether a design will suit the way she actually wears her hands.
Every piece is crafted and dispatched from the Surat workshop. Publishing the address is deliberate — you should know exactly where your ring is made.
The Engagement Gallery is where most stories begin — but it isn’t where our workshop stops. The same cutters and setters make lab grown diamond rings for every occasion, wedding bands for him and her, diamond tennis bracelets, necklaces and pendant sets, solid gold chains, and lab grown diamond earrings — each made to order in solid 9K, 14K, or 18K gold or platinum, never plated.
Whether you’re searching for lab grown diamonds in the UK for a proposal, a moissanite solitaire on a sensible budget, or coloured gemstone jewellery that doesn’t follow the crowd, the promise stays the same: IGI- and GRA-certified stones, about two weeks door to door, and nothing owed at delivery — from the city centre to the Peak District edge.
Some people fall for a setting. Others start with the stone. Browse IGI-certified lab-grown diamonds by shape, carat, colour, and clarity — live inventory, with the price you’d actually pay — then tell us the setting you want built around it.
Browse loose diamondsAbout 7 business days to craft your piece in our Surat workshop, then roughly 7 days of insured transit to any Manchester address — around two weeks in total. Fully custom designs take a little longer.
No. We ship duty-paid (DDP) to the United Kingdom. Duties and UK import taxes are settled by us before your order leaves the workshop, so the price at checkout is the final price. The courier will not ask you for anything at the door.
Checkout is in US dollars. You can switch the site to pounds to see an approximate price, but the amount charged is the USD figure — your bank converts it at their rate. Free express shipping applies over $500.
Yes — standard designs can be returned within 30 days, and we cover the return shipping and duties. Fully custom, made-to-spec pieces are non-returnable.
Every lab grown diamond is IGI-certified and every moissanite is GRA-certified. The certificate ships with your piece.
Sterling silver 925; yellow, white, and rose gold in 9K, 14K, and 18K; and platinum Pt950. Solid metal only — never plated or vermeil. Our white gold is palladium-based, nickel-free, and rhodium-finished, making it a strong choice for sensitive skin.
Order with our sizing guidance, or ask on a consultation call first — we’d rather get it right the first time. Because all manufacturing is in Surat, we can’t resize after delivery; a trusted local jeweller can handle sizing quickly and inexpensively. Read the ring resizing guide.
Pick a design and configure the metal, carat, and size — or commission something fully bespoke with our team.
Your piece is made to order at our family workshop — about seven business days at the bench, with certified stones set by hand.
Roughly seven days of insured, tracked transit. Duties and UK import taxes are settled before dispatch — you owe nothing at your door.
Around two weeks, door to door — anywhere in Manchester and across the UK.
The price at checkout is the price. Duties and UK import taxes are settled by us before your piece leaves India — the courier will not ask you for money at the door.
Standard designs, 30 days, full refund. We pay the return shipping and the duties. Fully custom pieces made to your specification can’t be returned — we’ll tell you which is which before you order.
Read the returns policyAgainst manufacturing defects, for as long as you own the piece. If something fails at the bench rather than in wear, we put it right.
Read the warrantyLab-grown diamonds arrive IGI certified, moissanite GRA certified. The paperwork is in the box, and the report number matches the stone you were sold.
