About Our Pricing

What does your pricing include?

FAQ

What is your turnaround time?

Craftsmanship is at the heart of everything we do, and each piece is meticulously handmade in our California workshop with a production time of approximately 4 to 8 weeks. Timelines may vary depending on the specifics of your order, but quality is never rushed.

Can I send you a stone to set into one of your rings or just buy your settings?

All of our rings are sold exclusively with one of our curated diamonds as a packaged set. Loose diamonds and settings are not sold separately.

What does diamond curation mean? How does the diamond selection process work?

If you’ve watched our YouTube videos, you’ll know we emphasize that a diamond’s beauty and brilliance cannot be judged by a grading report alone—it must be evaluated by the human eye. That’s why we meticulously curate and hand-select only the top 3–5 diamonds tailored to your preferences, ensuring you receive the best possible options that meet or exceed your expectations!

Are your diamonds ethically sourced?

At By Bonnie Jewelry, we believe that a diamond’s beauty should extend beyond its brilliance—it should also reflect ethical and environmentally responsible origins. Whether you choose a Natural Diamond or a Lab Diamond, we prioritize transparency and responsible sourcing throughout our entire jewelry-making process.

How to Measure Your Wrist

Finding the Perfect Size

You'll need:

  • A soft measuring tape
  • A pen or marker

Steps:

  1. Wrap the measuring tape snugly around the widest part of your wrist.
  2. Mark the point where the tape overlaps with a pen or marker.
  3. Adjust your measurement based on your preferred fit. We recommend:
    • For a close fit, add ¼” - ½” to your wrist measurement.
    • For a comfortable everyday fit, add ¾” - 1”.
    • For a relaxed, loose fit, add 1” - 1 ¼”.
  4. Refer to our size chart to find your ideal bracelet or bangle size.
