2.70 Ct.Tw.Total Carat Weight Tourmaline Pair from Mozambique

This matched pair of emerald cut green tourmalines presents precise technical attributes that make them exceptional candidates for a halo setting, the left stone weighing 1.33 carats with dimensions 7.40 by 5.84 by 3.93 millimeters, and the right stone weighing 1.37 carats with dimensions 7.57 by 5.64 by 4.17 millimeters. Both stones exhibit classic step cut geometry with long rectangular tables and graduated step facets across the crown and pavilion, producing broad, clean flashes of light rather than scintillation oriented around brilliant facetting. Clarity is graded very very slightly included when evaluated at eye level, and the excellent polish and well defined facet junctions enhance light return and edge crispness. Color presents at medium intensity with evenly distributed saturation, and the stones have been heat treated to optimize hue and stability. Origin from Mozambique is consistent with the clean crystalline structure and uniform zoning evident under loupe examination, and the measured proportions yield a well balanced crown to pavilion relationship that maintains depth without appearing windowed under typical face up viewing.

In a halo setting these technical characteristics translate into a design advantage, as the broad table and stepped facet planes serve as a canvas for a precisely calibrated halo of melee diamonds. A narrow single row halo of small brilliant cut diamonds set closely to the girdle lines will frame the rectangular outline, increasing perceived size and enhancing perceived color saturation through contrast with near colorless accents. For maximum optical impact select a cool white metal such as platinum or 18 karat white gold to provide high contrast and to promote crisp white reflection from the halo, while a warm yellow gold halo can be chosen to deepen the green tone for a vintage appearance. Prong placement should prioritize unobstructed table view and secure the corners typical of emerald cuts, or a partial bezel that leaves the crown facets free will protect girdle edges while maintaining the step facet signature. The slight size difference between the stones is modest and works well for a pair of earrings, matched ring and pendant, or an asymmetric two stone design where orientation and halo proportions are adjusted to equalize visual weight. For detailed mounting plans and gem matching recommendations please consult The Natural Gemstone Company to ensure the halo proportion, diamond color and metal choice optimally complement the unique facet architecture and color of these tourmalines.
