Questions04

Before you choose a shape.

  1. The difference lies in value, quality, and trust.

    • Value: We consistently offer prices not only below natural diamonds, but also lower than most lab-diamond retailers.
    • Quality: We select only CVD-grown diamonds, certified by IGI or GIA — and re-verified in-house by our own gemologist, both the certificate and the stone itself.
    • Heritage: Rooted in New York's Diamond District since 2011, we craft every piece in-house — from sourcing to setting, with no middlemen.
    • Customization: Owner-made and custom-made, from classic solitaires to one-of-a-kind creations designed around your vision.

  2. Yes — lab-grown diamonds are 100% real diamonds. They are graded by the same international standards (the 4Cs: cut, color, clarity, carat) as mined diamonds. Each Bow Tie Lab Diamond is certified by IGI or GIA.

  3. All Bow Tie pieces are made to order. Standard designs are typically crafted in 5 to 7 business days, while custom pieces take at least 3 weeks. Once ready, every order ships via FedEx Next Day delivery — fully insured, with tracking sent the moment it's on the way.

  4. Yes. Bring a shape, a stone or a photo to the Custom Studio. We draw it with you, choose the stone together and set it at our bench on 47th Street.
