Good to know
Frequently asked questions
Are lab-grown diamonds real diamonds?
Yes — a lab-grown diamond is a real diamond, chemically, physically and optically identical to a mined one, with the same 10/10 hardness and brilliance. The only difference is origin: ours are created responsibly rather than mined. We work only with lab-grown.
Are your diamonds certified?
Every diamond is independently certified by GIA, IGI or GCAL, so its quality is documented and verifiable.
How are Margot Vane pieces made?
Each piece is handcrafted to order in our in-house NYC atelier by our own bench jewelers — artisans with 10 to 15+ years of experience. Nothing is mass-produced; every ring is made one at a time.
What does "made to order" mean for me?
From the first conversation to the final polish, your piece stays in-house and passes through familiar hands — sketched, set and finished with the same care from beginning to end. It means a little more time, and a piece made properly.
How do lab-grown diamonds compare to mined diamonds?
They offer the same beauty as mined stones, created responsibly — no mining, and no harm to people or the planet. Best-in-class quality, without the extra markup.
Are they ethically and environmentally responsible?
Yes. Because every diamond is lab-grown, there's no mining — and none of the environmental or human cost that extraction can carry.
What metals do you use?
Lab-grown diamonds set in 14k and 18k gold — yellow, white and rose — and platinum, chosen for beauty, durability and integrity.
Will my piece last a lifetime?
Every stone is set by hand with deliberate attention to symmetry and long-term security. Each piece is made to endure — meant to be worn, kept and passed down.
Do you offer custom pieces?
Yes — made-to-order is at the heart of what we do. Have a piece in mind or a custom request? We'd love to hear what you're dreaming of and help bring it to life.
What do you make?
Engagement settings, loose lab-grown diamonds, and earrings — each made to order.
