2.04 Ct. Tourmaline from Mozambique

This 2.04 carat emerald cut brownish pink tourmaline presents a studied combination of precise cutting and superior material characteristics, offered by The Natural Gemstone Company. The stone measures 8.77 x 6.08 x 4.80 mm, and exhibits an emerald cut with well defined step facets and gently truncated corners that emphasize planar color zones and directional flashes. Clarity is graded very slightly included evaluated at eye level, which means that inclusions are minimal and do not interrupt the overall transparency when set for normal viewing distances. Color intensity is classified as intense, a strong saturation that reads immediately to the eye and translates into vivid presence in jewelry. Polish is excellent across the table facets and bezel facets, which speaks to meticulous lapidary technique and precise control of polishing laps and diamond grits during the final finishing stages. Enhancement is heat treated, and the treatment is disclosed as standard practice used to stabilize and refine the natural hue. Origin is Mozambique, a region noted for producing tourmalines with robust chroma and complex color zoning, and provenance is part of the technical profile we provide with every piece.

From a faceting and proportion perspective this emerald cut has been executed to optimize both color saturation and directional light return. The overall depth measures 4.80 mm, which yields an aggregate depth ratio of approximately 64.7 percent when referenced to the mean of length and width. This depth ratio falls into the preferred range for step cut rectangles, allowing the pavilion steps to present broad contiguous flashes of color rather than excessive windowing or darkness. The emerald cut crown and pavilion planes are arranged in successive parallel steps, each plane precisely aligned to maintain symmetry and to control the path of light through the crystal lattice. The larger table facet provides a clear window into the body color and internal features, while the bezel facets and crown steps moderate the return of light to produce a calm, even color field with occasional flashes at facet junctions. The girdle has been faceted and finished to a controlled thickness, minimizing susceptibility to chipping while allowing secure setting options. The combination of intense color intensity and a very slightly included clarity grade means that in many mounting designs the stone will read as eye clean and strongly colored, qualities prized by both connoisseurs and designers.

The genesis of this tourmaline can be traced to deep seated geological processes that took place millions of years ago in Mozambique, where late stage granitic pegmatites formed during the final cooling phases of a crystallizing granite body. These pegmatitic environments concentrate volatile rich melts, including boron bearing fluids, and provide the chemical milieu necessary for tourmaline crystallization. As the melt cooled slowly, large prismatic crystals were able to grow, incorporating trace elements such as manganese and iron into the crystal structure. Manganese acts as the chromophore that produces pink to red hues in tourmaline, while varying ratios of iron and other transition metals introduce brownish overtones and modulate saturation. The crystal grew in zones, layer upon layer, and microscopic growth discontinuities, fluid inclusions, and fine needle like mineral inclusions became trapped within the lattice. Over geological timescales these pegmatites were uplifted, weathered, and exposed, allowing miners to recover well formed crystals. The particular interplay of trace element chemistry and slow growth is what yields a brownish pink bodycolor with the depth and complexity evident in this specimen.

When evaluating this gem for purchase consider the technical advantages it offers as a wearable centerpiece. The emerald cut showcases color in a restrained, sophisticated manner, making it ideal for engagement rings and classic pendants where a controlled play of light and a bold field of color are desired. The very slightly included clarity evaluated at eye level reflects a material that retains strong transparency and minimal blemish visibility, while the excellent polish ensures clean facet junctions and minimal surface abrasion after setting. The heat treated enhancement has been applied to bring out the stone s optimal hue and to ensure color stability under common wear conditions, and the Mozambique origin provides a geological narrative that enhances provenance and collector interest. At The Natural Gemstone Company we emphasize full disclosure of origin and treatment, and we present this 2.04 carat emerald cut brownish pink tourmaline as a technically refined gem, ready to be incorporated into fine jewelry where its combination of cut, color, and craftsmanship can be fully appreciated.
