Custom Design · Guided by Himmat
Bring Your Vision to Life.
Begin with a sketch, a reference image, or simply an idea. Himmat will help you shape the proportions, setting and details around how you want the piece to look and feel.
Choose every element: an IGI-certified lab-grown diamond or GRA-certified moissanite; solid 9K, 14K or 18K yellow, white or rose gold; Platinum Pt950; or Sterling Silver 925.
Approve before we craft: we confirm the design, specifications, expected timeline and price before production begins in Surat. Fully custom and made-to-spec pieces take longer and are non-returnable.
The first thing everyone notices is how bright the diamond looks. Even under normal indoor lighting it catches the light beautifully. The craftsmanship is excellent, and every detail looks clean and well finished.
I wanted a ring that would still look beautiful years from now, and this design feels completely timeless. The band is comfortable, the setting feels secure, and it pairs perfectly with my wedding band.

Answers last updated July 2, 2026
Will I have to pay customs duties or import fees?
No — you pay $0 at delivery. Signora Jewels ships every US order with all customs duties and import taxes prepaid (DDP), so your checkout price is final. Since the US ended its $800 duty-free exemption in August 2025, every jewelry import is assessed duty — ours is simply paid by us before your piece ships from our atelier.
Are lab-grown diamonds good for engagement rings?
Yes — over half of new US engagement rings now feature lab-grown center diamonds. They are real diamonds with identical brilliance and Mohs 10 hardness, and the lower price means lab-grown center stones average larger than mined ones at the same spend. Signora Jewels makes every lab-grown diamond engagement ring to order with IGI certification.
Is IGI certification as good as GIA for lab-grown diamonds?
Yes — IGI is the industry-standard laboratory for lab-grown diamonds, grading the majority worldwide (roughly 65% market share) on the same 4Cs used for mined stones. Every Signora Jewels lab-grown diamond comes with an IGI report, and the report number is laser-inscribed on the diamond’s girdle so you can verify it free at igi.org.
How long does it take to get an engagement ring from Signora Jewels?
About two weeks from order to your US doorstep. Each engagement ring is made to order at Signora Jewels’ Surat atelier in your chosen size and metal — 9K, 14K, or 18K gold or platinum — then shipped fully insured and tracked with all US duties prepaid. Shipping is free on orders over $500.
Do lab-grown diamonds hold their value?
Honestly, no — lab-grown diamonds resell for less than mined diamonds, whose own resale is typically only 25–50% of retail. Buy lab-grown for beauty and size-per-dollar, not investment: the much lower purchase price is what offsets the resale gap, letting you afford a larger, higher-clarity IGI-certified stone for the same budget at Signora Jewels.
Is it safe to buy an engagement ring online from an overseas jeweler?
Yes, when the classic risks are covered. Signora Jewels ships every US order fully insured and tracked with all duties prepaid, backs standard designs with a 30-day return policy, and certifies each lab-grown diamond with IGI — the report number is laser-inscribed on the stone and verifiable free at igi.org, so you can independently confirm what you bought.
