Faux Turquoise Pin

No manufacturing information I can find - that doesn't mean there is not a mark that I can't find. I am not a collector or dealer of jewelry and am just selling what I've collected for personal use over the last 40 years. This pin/brooch is almost 2 inches across. I do not know the metal content, but it shows no wear or damage. I always wondered if the smaller stones were genuine, because they have the normal striations of turquoise. If they are man made, then care was taken to give a natural appearance. The clasp is in an undamaged secure condition. Please email for a photo of the back. The large stone has what looks like a manufacturing flaw. You feel it more than see it, because it is like a tiny bump. It does not look or feel like damage. All stones are in place and tight. If you have any questions or would like additional photos, please email. I need your zip code to calculate the postage.
