Why these prices are possible
- Lab-grown supply economics. Growing gem-quality diamond above ground removed the scarcity premium. Same crystal, same grading scales, radically different price.
- No retail middleman. We design, cast, and set in our own Diamond District studio and sell direct. A traditional retail chain adds a keystone markup between the workbench and the display case — buying direct removes it.
- No showroom overhead built into the stone. You're paying for the diamond and the craftsmanship, not a flagship lease.
What should make you suspicious of a price
- No independent certificate on a stone over ~1 carat. Grading is what makes a price comparable at all. Every eligible stone we sell is IGI certified and laser-inscribed.
- Vague specs. "H color-ish" and "eye clean" are not grades. Look for the letter and the clarity grade on a report.
- A price too far below the market. If a "3-carat D VS1" costs $400, it's a simulant or the grades are fiction.
