Values based on locations

Hi, I am pretty new to the gemstones game. I was wondering if gems are more valuable or less valuable based on the location they were found or mined in? Is that a thing? I recently found an attraction to many gems when I was in certain countries in the middle East. I was worried about the ramifications of purchasing these gems from countries amidst a war or whether or not it would lower their value. Any ideas?

Sure that could matter, but the bottom line is that it all depend on what you have. Do you know what you bought? Post some pics.
