Description

This 17.61 ct Rubellite from Antsirabe, Madagascar combines impressive size, a striking violet pink color, and an unusual flat trillion cabochon cut. With its bold outline, smooth surface, and expressive natural character, it is a gemstone that stands out clearly from more conventional faceted stones and offers excellent potential for bespoke jewelry as well as for a fine gemstone collection.

Rubellite is especially valued within the tourmaline family for its rich pink to red color range and its lively, elegant appearance. This stone shows an attractive violet pink tone that feels vivid and refined at the same time, giving it a distinctive presence with both warmth and individuality. In cabochon form, the color appears especially smooth and concentrated, while the polished surface creates a soft glow rather than the sharper reflections of a faceted gem.

The flat trillion cabochon cut gives this rubellite a particularly original and modern look. Its triangular shape creates a strong design identity, while the flatter cabochon profile emphasizes color, outline, and natural character in a very direct way. This makes the stone especially suitable for statement rings, bold pendants, and one-of-a-kind designer jewelry in which the gemstone itself defines the style of the finished piece.

At 17.61 ct, this rubellite has substantial visual impact and clear collector appeal. Originating from Antsirabe, Madagascar, it combines notable provenance with uncommon cutting and vivid color, making it attractive not only for important jewelry creations but also for collectors who appreciate exceptional colored gemstones with individuality.

A remarkable flat trillion cabochon rubellite from Madagascar with vivid violet pink color, unusual shape, and outstanding potential for bespoke jewelry or a refined gemstone collection.
