I agree with Rosanna: can you, please, send an another pic? because I saw so much fake chevrons which are an elaborate imitation bead with some salt, sand or acid .... to persuade that she is old and it's difficult, sometimes, to see what it's fake or true. We can't see exactly the whole bead and it's a little vague: it's would be better with the whole bead not so near and the from the side. Is it possible?
