大型巴西电气石（Schorl 黑电气石 + Verdelite 绿电气石），具绿色透明度 – 5315 g

宏伟而迷人的天然样本，含有明显的 Verdelite 区域（绿电气石）的 Schorl（黑电气石），来自巴西——全球最著名的电气石产区之一。
该样本呈现发育良好的棱柱状晶体，具有明显的垂直平行条纹，这是电气石的典型特征。晶体结构清晰，赋予作品强烈的美学冲击力。
最具吸引力的特征之一是存在的绿透明区域，在逆光照射时尤为明显。这一效果源于晶体在不同生长阶段的自然分区，受到收藏家特别欣赏。

Impressive natural specimen of black tourmaline (Schorl) with visible green tourmaline (Verdelite) zones, originating from Brazil, one of the most important sources of high-quality tourmaline.
The specimen features well-developed prismatic crystals with strong vertical striations, typical of tourmaline. The crystal structure is clearly visible and gives the piece a strong visual impact.
A particularly attractive feature is the presence of green translucent areas, clearly visible when the specimen is backlit. This effect is caused by natural crystal zoning formed during different growth stages and is highly appreciated by collectors.
The piece is partially embedded in its original pegmatitic matrix, likely composed of quartz and feldspar, enhancing its natural and aesthetic appeal.
