Bench Notes on C4 Tone & Elongated Oval Mounting:
C4 sits in the warm honey-gold range of the champagne color scale. Step cuts feature flat, parallel facets that emphasize body color and clarity over surface brilliance. How that color presents in a finished ring depends on the mounting choices:

• Metal Choice: Setting in 14K or 18K yellow or rose gold unifies the honey-gold body color with the setting. Setting white prongs or a platinum head around the stone creates a clean contrast that frames the slender oval outline.
• Elongated Proportions: At 6.89mm long by 3.70mm wide, this stone features an elongated 1.86 length-to-width ratio suited for north-south solitaires, modern east-west mounts, or protective bezel settings.
• Basket Design: Parallel step facets require clear light entry through the sides and pavilion. An open wire basket allows light to pass through the stone without dampening its body color.

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. Insured transit and U.S. customs entry from our partner vault typically take 4 to 7 business days to reach our Brookline bench for your 7-day private viewing window. This deposit covers fully insured 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).
