Anyone here investing in gold?

Just want to know if anyone here is investing in gold and if it is worth it. I (35 F) just recently started my gold collection. I initially am not into gold accessories but my students and their parents (I am in the Middle East) give me gold jewelry as gifts every end of the school year so I now have a little collection of gold. I have also recently started buying piece by piece. I just want to know if this is a good investment or just stop collecting? Pros and cons? Thank you.

UPDATE: Thank you very much to all who took time and responded to my post. It was really good hearing your thoughts and gave me a better idea about investing in gold. I am located in Dubai, UAE so there are plenty of options when buying. Again, thank you all and I will keep your tips in mind.
