Write a Sri Lankan jewelry... There are many gem shops near Galle Castle ... Moslin has more shops, but the individual is not very recommended. Although things are cheap and do not guarantee quality, you need to buy a gem to buy a CIA certificate ... In addition to color, purity, cutting, The gemstones are divided into fire and not burned. The market is more than 90 [%]. The CIA certificate has been written on it. Basically, the gem shops have Chinese. The bargaining price is at least half price. The ability depends on your ability. I went to several jewelry stores. There is a jewelry store that has been open for more than 60 years. It is the best one I have ever been to. Many people who don't understand will say it is expensive. People who understand will not say it. I also bought a sapphire ring and starlight sapphire ring at half price. It feels very good! If you know gems very well, there is also a gem market in Sri Lanka. Near the mine, you can pick stones yourself and go back to find someone to cut and polish the gems. Buy gems carefully ... Don't buy ... if you don't understand.
