4.84 Ct. Tourmaline from Tanzania

This pink tourmaline presents a precise balance of weight, proportions, and finish, offering a refined option for the connoisseur. At 4.84 carat the stone measures 12.22 by 8.51 by 5.93 millimeters, presented in a classical emerald cut that emphasizes linear light return and color saturation. The clarity grade is very very slightly included when evaluated at eye level, which translates to minor internal features that do not detract from the visual transparency or the clean table window. Color is evaluated at an intense intensity, a saturated mid to deeper pink with excellent hue purity and minimal brown or orange modifiers, a characteristic that is particularly desirable in tourmalines from Tanzania. The surface finish is of excellent polish, every facet meeting with crisp junctions and minimally noticeable facet openness. This specimen has been heat treated to stabilize and intensify the pink hue, a standard and stable enhancement for tourmaline, and The Natural Gemstone Company documents the treatment and origin as Tanzania in our inventory notes.

The emerald cut faceting schema employed on this stone has been executed to maximize both color evenness and step related luster. The open table and broad step crown planes allow uninterrupted view into the pavilion, while the parallel pavilion steps are calibrated to preserve depth of tone without creating heavy windowing or extinction. Proportions have been judged to produce controlled light leakage, so the gem appears lively under varied lighting conditions, with even color distribution from table to girdle. Facet junctions are aligned to maintain symmetry, and the girdle thickness is consistent so that setting preparations can be made with minimal rework. The cutter has intentionally emphasized longer step facets along the length to reinforce the emerald cut silhouette, granting the stone architectural elegance and optical stability. The excellent polish accentuates facet brightness and enhances the perception of clarity, allowing the very very slightly included clarity grade to remain a technical descriptor rather than a visual limitation.

From a durability and daily wear perspective this pink tourmaline is well suited to routine jewelry use when properly set and cared for. Tourmaline registers between seven and seven and a half on the Mohs hardness scale, a hardness that resists abrasion from everyday contact while remaining workable for precise cutting and setting. Toughness is generally fair to good in tourmaline, with no true basal cleavage that would create a pervasive weakness, however the crystal structure does admit localized brittleness, so protection from sharp knocks and hard impacts is prudent. For daily wear in rings we recommend a protective setting approach, such as a bezel or raised gallery with secure prongs, to shield the corners inherent to an emerald cut. The heat treatment applied to enhance color is considered stable under normal wearing conditions, but exposure to sudden thermal shock should be avoided. Routine exposure to harsh chemicals and abrasive cleaning agents can affect polish and metal work, and aggressive ultrasonic or steam cleaning is not recommended without prior consultation, therefore gentle cleaning with mild detergent and a soft brush is the preferred maintenance method.

Provenance and craft context add measurable value to this piece, making it appropriate for a bespoke commission or a refined production setting. The origin from Tanzania places the stone among a known source of well colored tourmalines, and our documentation through The Natural Gemstone Company includes the origin and enhancement details for transparency. The combination of an intense pink hue, very very slightly included clarity at eye level, and an excellent polish make this gem versatile for a variety of design languages, from clean modern solitaires to architectural halo settings that complement the step cut geometry. Given the measured dimensions and weight, typical ring sizes will display an elegant presence on the finger without overwhelming proportionality, and the emerald cut profile allows for secure bezel or prong attachments with minimal pavilion reduction.
