I like collecting gemstone. This is a hobby, not an investment. Amber is one of the most popular gemstones in recent years, while diamond is also a classic stone in the world. It is hard to say which gem is good or not as it has its beauty. If you want to buy one for investment, you need to consider the worth. If you just put it in your jewellery, you can choose what you like at an affordable price. I will post some articles for you to show the different natural stone.
