[QUOTE="Bronwen, post: 1055670, member: 5833"]It is undoubtedly elephant ivory. As far as I can determine, France was the source of these & Dieppe was the major ivory working center. Like many older ivory pieces, this one has developed some fine cracks. The only place you may find Schreger lines on this one is at the truncation line, the surface where the neck cuts off. They are only visible in cross section; the piece overall has been worked with the grain & the cracks have developed in that direction. Schreger lines are more conspicuous toward the outer edge of a tusk, so you may not find any if this piece of material came from deeper in. If you scroll through the examples in these boards, you will see that the fine cracks are fairly common: [URL]https://www.pinterest.com/cameotimescom/ivory-cameos-reliefs/[/URL][/QUOTE]
