1.04ct Natural White H/SI1 Elongated Old Mine Cut Diamond

Overview: A natural 1.04ct white diamond (H color, SI1 clarity) cut in an elongated Old Mine profile. Its subtle 1.19 length-to-width ratio creates a flattering look on the finger, while broad antique facets give it traditional vintage fire.

Vault Availability: Held in our supplier's U.S. vault. Daily changes in live wholesale availability mean direct online checkout is disabled. If this exact gem sells before your in-person order is locked in, our jeweler will immediately source similar options in cut, color, and budget for your review.

Want to see this stone in person?
We invite you to visit our Brookline shop to sit down with our bench jeweler and begin your project. To view this stone in person, we require a $500 Vault Sourcing & Design Deposit to order it in for you. Fully insured transit from our domestic U.S. partner vault typically takes just 2 to 3 business days to reach our Brookline bench for your 7-day private viewing window. This deposit covers transit, custom 3D CAD design renderings for your mounting (with up to 2 revisions), and a physical 3D resin model to try on, with 100% applied toward your finished ring total.

What if the stone isn't the right fit?
If you view the stone in person and prefer a different color, shape, or size, your $500 deposit transfers completely toward sourcing an alternate vault gem or crafting your custom setting.

Note: The $500 deposit applies specifically to Vault 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). Every setting is built from scratch, so the final cost depends entirely on the specific design we create together—ranging anywhere from $2,000 for compact gems to $10,000+ for rare high-carat stones. Exact, binding quotes are provided during your in-person consultation (or shortly after, should Igor need time to calculate intricate bench labor or source specific accent stones). Looking to maximize stone scale within a specific budget? Custom engagement rings using our in-house lab-grown diamonds start at $2,000. Start your custom ring inquiry here.
