Update, part 2. I went to Brazil with my family. Loved it. I didn’t buy as many gemstones as I would have liked (I imagined I’d find a giant warehouse / market / street fair with stones everywhere, and me leaving with two full suitcases, but that wasn’t the case), but Rio de Janeiro is more beautiful than I could have imagined so I let that expectation go. We did go to a couple of small gemstone museums / jewelry stores, and they had great examples of rough, award-winning specimens, and a large selection of stuff for sale (but more on that in a later post).
