The Regent Diamond represents one of the most valuable colorless diamonds ever discovered, with a price driven by rarity, history, and exceptional cut. Understanding its market valuation requires looking beyond carat weight to clarity, origin, and public auction context.
Because this stone is not traded daily, pricing insights come from auction records, museum insurance values, and expert appraisals rather than open market listings. The following sections break down the key factors that shape the Regent Diamond price.
| Attribute | Details | Impact on Price | Reference Source |
|---|---|---|---|
| Origin | Discovered in the Golconda region of India, circa 1698 | Historic Golconda origin adds a significant premium | Gemological literature and museum archives |
| Weight | 140.64 carats rough; 141 carats polished | Large size places it among top-colorless diamonds globally | Smithsonian and French mineralogical records |
| Color Grade | Type IIa, colorless, historically described as near-colorless to white | Top color grade strongly supports elevated valuation | Published gemological reports and historical descriptions |
| Clarity | VS to VVS range with minor inclusions visible under magnification | High clarity adds value but is secondary to color and provenance | Expert gemological assessments |
Historical Auction And Sale Pricing
Publicly documented sales of the Regent Diamond remain limited, yet each recorded transaction influences how the market estimates its value today. Professional appraisers reference these events when modeling price scenarios for comparable large colorless diamonds.
Adjustments over time reflect currency fluctuations, insurance replacement costs, and evolving collector demand. This means the Regent Diamond price is best understood as a range rather than a single fixed number.
Current Market Valuation Methods
Valuing a legendary gem like the Regent relies on comparative sales of exceptional colorless diamonds, discounted cash flow models for museum pieces, and insurance replacement estimates. Appraisers consider the cost to source, cut, and insure a similar quality stone in the current market.
Because the diamond is part of a national collection and not listed for sale, analysts rely on proxies such as the Graff Pink, the Idol’s Eye, and other Golconda-origin stones to benchmark price per carat. These benchmarks, combined with macroeconomic factors, shape the estimated valuation range.
Ownership History And Influence On Price
The ownership trajectory of the Regent Diamond from its mining in India to the French crown affects its rarity premium and desirability. Provenance documentation, exhibition history, and royal associations are included in valuation models as intangible value drivers.
Collectors and institutions often assign higher values to gems with clear historical narratives, which helps sustain elevated price estimates even in uncertain markets. This historic narrative is a core component of how the Regent Diamond price is framed by experts.
Gemological Specifications Driving Value
Cut quality, symmetry, and craftsmanship influence light performance and market desirability, which in turn affect the Regent Diamond price. Although recutting is not an option today, its original French cut remains a benchmark of 18th-century lapidary skill.
Advanced gemological analysis, including spectroscopy and growth zoning studies, helps authenticate origin and treatment status. Full transparency about these specifications supports more accurate price assessments by institutions and insurers.

Experts use historic sale proxies, price per carat benchmarks from top colorless diamonds, and insurance replacement models adjusted for size, color, and provenance.
Can the Regent Diamond price be compared to other famous diamonds like the Cullinan or Koh-i-Noor?
Direct comparisons are limited, but analysts do benchmark it against other large colorless stones of Golconda origin to derive relative valuation ranges and per-carat premiums.
