Antique cigar holder around 1900

Antique cigar holder (cigar mouthpiece) made of amber with two metal rings. The larger front ring bears an illegible hallmark and has a small dent. Dating to around 1900, it comes with its original leather case, embossed in gold letters with “ECHT NATURBERNSTEIN.” Used but well-preserved in its original condition. Age-appropriate signs of use. Dimensions: approx. 6.7 cm / 11 mm inner diameter / 8 g.
