While this specific gem has been acquired for a custom build, we can source similar natural options tailored to your preferred color, scale, and budget. Initial sourcing discussions and design estimates are complimentary with zero obligation. To reserve and ship curated partner gems to our Brookline shop under fully insured transit, a $500 deposit holds your stone, starts your custom 3D CAD design, and applies 100% toward your finished ring. Live partner inventory moves quickly across international trade vaults. Should a requested stone sell to another jeweler right before our hold goes through, we will gladly source comparable options for your review or issue a full refund if you prefer not to proceed. Once your stone is secured and CAD design begins, your deposit remains active as a dedicated credit toward your finished ring.

Master Jeweler’s Setting Ideas
To help you picture how a loose gemstone translates into a finished piece, we've combined Igor's 40+ years at the bench with a few different setting ideas:
18K Yellow Gold
Tapered Baguettes
Platinum
Claw Solitaire
18K Yellow Gold
Modern Bezel
Design Previews: These digital renderings are just to give you a feel for color, metal contrast, and setting styles. They are not final blueprints. Click any image to enlarge.
- Metal Pairing: Setting this teal sapphire in yellow gold draws out the stone's warm green notes, while mounting in platinum or white gold frames the blue undertones for a crisp, cool look.
- Style Ideas: Shown above in a low-profile double-claw setting with tapered baguette side stones, a clean platinum solitaire, and a full protective yellow gold bezel.
- At the Bench: The smooth, curved oval outline has no vulnerable points or fragile corners, making it versatile for claw prongs, flat tabs, or low-profile bezel mountings.
Craftsmanship: While digital renderings are great visual guides, the actual ring is built for real-world wear. Igor personally plans your specific mounting, calculating precise prong thickness, gallery depth, and structural support during your 3D design phase to guarantee a lifetime of durability.
Looking to create something similar?
If you love this look, we invite you to reach out or visit our Brookline shop to get started. We will search our supplier vaults free of obligation to share what natural sapphires match your preferred size and budget. Once you select the stone you would like to view in person, we require a $500 Vault Sourcing & Design Deposit to bring it in. Bringing your gem safely to our Brookline studio usually takes 4 to 7 business days, giving you a private 7-day viewing window. This non-refundable deposit covers fully insured transit, custom 3D design renderings for your setting (including up to 2 revisions), and a physical 3D resin model to try on. Best of all, the full $500 applies 100% toward your finished ring.
What if the sourced gem isn't quite right?
Your deposit remains completely versatile. It transfers 100% as a project credit toward sourcing another natural gem, choosing an in-house lab-grown diamond, or crafting a custom setting.
Note: The $500 deposit applies specifically to sourcing natural gemstones and is credited 100% toward your finished project. Final custom ring totals are calculated simply as: Selected Gem Price + Custom Mounting Design (plus applicable MA sales tax). Since every setting is built from scratch, the final cost depends entirely on the specific design we create together, ranging from around $2,000 for compact gems to $10,000+ for rare, high-carat stones. Exact quotes are provided during your in-person consultation (or shortly after, if we need time to calculate intricate bench labor or source specific side stones). Looking to maximize stone size within a specific budget? Custom engagement rings using our in-house lab-grown diamonds start at $2,000. Start your custom ring inquiry here.
