Maybe. To be honest pamor identification is not my strongest suit. Could be Bendo Sagodo though.
Given the type of setting used and the over all quality of the mendak itself i would tend to think these "stones" are more likely glass. But i don't really know of any way to properly identify gemstones through internet photos. The only way to be sure about what these are would be to bring them into a jeweler and have them take a closer look. I've done this before and in most cases jewelers are quite interested seeing something as unusual as this in their day-to-day business, especially if they do indeed turn out to be gemstones as opposed to glass or paste. I've never been charged for such an assessment. Can't guarantee you will have the same luck, of course.
