6.81 Ct. Tourmaline from Brazil

This 6.81 carat oval pink tourmaline presents precise proportions and exemplary finishing, suitable for collectors and high end custom jewelry, The Natural Gemstone Company offers this transparent stone with dimensions of 14.67 x 11.10 x 7.07 mm, a length to width ratio of approximately 1.32, and a depth percentage of approximately 54.9 percent, values that fall into the preferred range for oval gems, the mixed brilliant cut combines a brilliant style crown with a carefully faceted pavilion to optimize both dispersion and overall light return, the table is generous enough to showcase the gem face up while the pavilion depth and facet arrangement minimize windowing and preserve strong face up color, the clarity grade is very very slightly included evaluated at eye level, meaning the stone reads effectively eye clean, the polish is excellent and the symmetry is carefully executed, the origin is Brazil and the stone has been heat treated, a standard and stable enhancement that intensifies the body color without compromising structural integrity.

The mixed brilliant faceting scheme used here is calibrated to enhance the inherent optical properties of tourmaline, the crown features a conventional brilliant array of star and bezel facets which scatter incoming light into lively scintillation across the table, the pavilion employs a combination of modified pavilion mains and triangular facets that deliver return rays to the viewer, these facet relationships produce a balance between contrast and brilliance, the refractive index range for tourmaline typically centers around 1.624 to 1.644 with birefringence that can create subtle doubling of facet edges, this stone exhibits pleasing dispersion given the cut proportions, pleochroism is present in tourmaline and this specimen shows directional saturation changes between slightly purplish pink and vivid warm pink tones when rotated, when setting this stone attention to orientation will preserve the most saturated face up color by aligning the long axis with the crystal optic axis.

Clarity wise the stone is graded very very slightly included at eye level, inclusions are minimal and do not interfere with the primary light paths or with the overall visual appeal, the excellent polish enhances both surface luster and the precision of facet junctions, the girdle has been finished to a consistent thickness to facilitate secure prong or bezel mounting, heat treatment carried out on this tourmaline was controlled to intensify hue and remove potential brownish modifiers, this procedure is stable and common practice in the trade for Brazilian tourmalines, it does not create structural weaknesses, the stone responds well to standard professional cleaning and routine care precautions apply, The Natural Gemstone Company documents origin and treatment so that the gem can be designed into heirloom quality pieces with full disclosure.

For custom design options, this 6.81 carat oval pink tourmaline adapts elegantly to multiple jewelry archetypes, in a solitaire ring the stone will command presence when elevated on four or six low profile prongs to allow light into the pavilion while maintaining security, a bezel in warm 18 karat rose gold will intensify the pink and provide a contemporary aesthetic, alternatively a platinum or 18 karat white gold setting with a discreet halo of round brilliant diamonds will accentuate brightness and create contrast, for colored stone pairings consider a graduated arrangement where small round tsavorite garnets or chrome tourmalines are set as accent stones to the sides, the green to emerald green saturation of tsavorite creates a complementary color contrast that emphasizes the pink hue, for a subtler palette choose morganite or pink spinel accents in lighter tone to create a monochrome, tonal composition that reads refined and cohesive.

When planning a bespoke piece designers should account for optical orientation and supporting accents, place the pavilion culet and main facet orientations to minimize light leakage, select diamond accent grades that will harmonize rather than overpower the pink body color, near colorless diamonds in G color and VS clarity or better will provide brilliance without introducing unwanted color interaction, custom shaped accent stones such as tapered baguettes or elongated navettes can echo the oval axis and create flow, for greater impact consider a three stone composition with two tapered green tourmalines flanking the central oval, metal choice will alter perceived saturation, warm alloys increase apparent depth and create a vintage expression, white alloys maximize crisp contrast, The Natural Gemstone Company can provide mock up CAD renderings and hand sketch proposals to illustrate these combinations and to determine exact measurements for settings and accent stones, our lapidary and design partners calibrate facet alignment and setting plans to preserve the gem face up color and to ensure secure mounting for daily wear.
