🏔️ Collector's Piece: 3.8ct Deep Blue Mt. Antero Aquamarine
This is a Museum-Quality Collector's Piece, an exceptional $3.8\text{ct}$ Aquamarine with significant provenance and artistry.
Source and Rarity: Mt. Antero Blue Star Claim, U.S.A.
North American Provenance: This gem was ethically sourced from the Mt. Antero Blue Star Claim in Colorado, U.S.A., a renowned, high-altitude locality famous for producing some of the finest American beryl. Gems from Mt. Antero are highly sought after by collectors due to their limited availability and American origin.
The Coveted Dark Blue: Aquamarine is typically a light, delicate sky-blue. However, this specimen exhibits a darker, more intense blue than is common for the species, especially for Mt. Antero material. This deep saturation—often a signature of the best finds from this specific claim—elevates it far above the standard aquamarine, placing it in a rare and desirable class.
Precision Faceting
Custom Precision Cut: The rough material was entrusted to a master lapidary to maximize its unique color and brilliance. The stone features a custom precision facet design, moving beyond standard commercial cuts (like the brilliant or step cut).
Maximum Performance: This custom design uses specific, calculated angles and geometric patterns to overcome the pleochroism and relatively lighter tone typical of aquamarine, resulting in a phenomenal display of light return, superior sparkle, and a visual depth that maintains the rich, darker blue color saturation across the entire $3.8\text{ct}$ face.
Summary
This $3.8\text{ct}$ gem is more than just an Aquamarine; it is a convergence of rare provenance (Mt. Antero, U.S.A.), exceptional, dark color, and expert artistry (custom precision faceting). It is a top-tier investment piece perfect for the serious gem collector or as the centerpiece of an heirloom-quality custom jewel.
