Chapter 10: Choose Your Stone First
Choose Your Stone First
Live-sourced natural diamonds, lab-grown diamonds, and gemstones, now searchable by shape, carat, color, and clarity, before you ever look at a setting.

Most jewelers show you a finished ring and let the stone stay a mystery. I've always thought that was backwards, so I built the part of Bravais that lets you do it the other way: pick the stone first, on its own terms, and build the setting around it.
That part of the site just got a lot more useful. You can now search live inventory across three collections, natural diamonds, lab-grown diamonds, and gemstones, filtered by shape, carat, color, and clarity. Every result is a real, available stone, not a rendering or a placeholder. What you see is what you can order.
What's New
Three collections, each pulling live inventory:
| Natural Diamonds | Filterable by shape, carat, color, and clarity. Clarity disclosed exactly as it grades, I1 and SI2-SI3 included, never softened. |
| Lab-Grown Diamonds | Same filters, defaults to VS clarity and F+ color unless a listing says otherwise. |
| Gemstones | Filterable by stone type, shape, and carat. Treatment disclosed on every listing, heat, dye, clarity enhancement, or untreated, stated plainly. |
Once you've found the stone, it pairs with a custom Bravais setting, hand-carved and cast to fit that exact stone, or a Stack Pack or Bridal mounting sized to match.
How We Price
Every stone is priced on the same public schedule, no negotiation, no exceptions:
| $1 – 1,500 | 1.99x |
| $1,501 – 2,000 | 1.82x |
| $2,001 – 2,500 | 1.72x |
| $2,501 – 4,000 | 1.62x |
| $4,001 – 5,500 | 1.57x |
| $5,501 – 7,000 | 1.52x |
| $7,001 – 8,500 | 1.42x |
| $8,501 – 10,000 | 1.37x |
| $10,001 + | 1.32x |
Smaller stones carry a higher multiple to sustain the cost of sourcing, disclosure, and hand-finishing at every tier. No warehouse, no showroom, no sales floor. You're paying for the stone, the sourcing relationship, and the hand that sets it.
Because inventory updates in real time, availability and exact pricing can shift between the moment you browse and the moment you order. The number you see at checkout is the number that holds.
For Something Rarer
Some stones don't move through a calibrated supply chain at all, and that's exactly what makes them worth pointing you toward. Natural Canadian-origin diamonds and Australian sapphires through Misfit Diamonds. Hand-cut, unusual-cut stones through Caleb Quashen, who I purchase from annually for Stone & Wild. Precision fantasy cuts through John Dyer. These aren't part of the live feed and I don't hold or track their stones, I point you to their work as inspiration, and if something resonates, I source it as a custom inquiry from there.
Start your selection, or reach out if you already know what you're looking for and don't see it yet. Custom stone sourcing is part of what I do.
