For those who don’t know what Yaqut is, let me explain. Yaqut is an arabic word meaning sapphire. The word is used for girl’s name in Arabic countries. However, when it comes to gemstone and specially red Yaqut then it means red sapphire. Red sapphire is known as ruby, so as per your saying you should wear an opaque ruby gemstone. BUT, ruby and blue sapphire don’t go together and they should not be worn together.
So, if you’re already seeing favourable situations by wearing blue sapphire then I would suggest you to continue wearing it and don’t go for ruby gemstone.
