无起拍价 ~ 天然黑电气石晶体，搭配石英与斜长石的组合 标本- 25 g - (7)
This lot consists of seven natural Black Tourmaline (Schorl) crystals associated with Quartz and Feldspar matrix.
The crystals display classic elongated prismatic habit with vertical striations typical of tourmaline. The contrast between the deep black crystals and the white quartz matrix enhances visual appeal.
Some pieces show clean terminations, while others are partially embedded in matrix. Minor edge contacts and surface imperfections are consistent with natural extraction.
Total combined weight: 30 grams.
All specimens are natural and untreated.
3 g – 31 × 12 × 10 mm
5 g – 30 × 15 × 10 mm
3 g – 18 × 9 × 8 mm
