0.15 Ct. Hauyne from Germany

This transparent 0.15 carat cushion shaped blue hauyne measures 4.74 by 3.36 by 1.60 millimeters, and has been fashioned with a mixed brilliant cut to balance optimal light return and face up color saturation. The mixed brilliant configuration pairs a brilliant style crown with modified pavilion faceting, producing strong scintillation from the crown facets while preserving depth of tone through controlled pavilion angles. Proportions yield an approximate depth of 39 percent, which gives a broad, vivid table presentation that maximizes perceived size for a stone of this weight. Clarity is graded slightly included at eye level, indicating small internal features that do not materially interrupt light transmission or overall transparency, and the excellent polish enhances facet definition and contrast. Color is a vivid, saturated blue, uniformly distributed, and the material is unenhanced, natural, and of German origin, attributes that collectively underscore its gemological integrity and desirability.

From an investment perspective this untreated German hauyne from The Natural Gemstone Company occupies a niche but increasingly recognized segment of the colored stone market. Transparent hauyne of vivid saturation and no enhancement is uncommon, and provenance from a historic European source adds provenance value that appeals to collectors and connoisseurs seeking verifiable, stable assets. The small size and superior cutting make this piece highly wearable and marketable, which can improve liquidity relative to uncut or poorly finished specimens. Because the stone is untreated, it avoids the market risks associated with heat or diffusion treatments, and the excellent polish and well executed mixed brilliant faceting increase appeal to both designers and investors looking for stones that perform well in jewelry without compromising rarity. Buyers should note that hauyne has moderate toughness and should be set accordingly to protect its surface and facets to preserve long term value. For clients who prioritize documented, untreated origin and superior cutting, this 0.15 carat cushion blue hauyne represents a technically compelling acquisition with realistic potential for appreciation as demand for distinctive, natural gem species continues to grow, and The Natural Gemstone Company can provide full provenance and handling recommendations to support long term stewardship.
