In the United States and Canada, the ring sizes are the numeric figures. Every region has its own measuring units and you can convert between these standards by using online size charts. The size starts from 0 and goes above 15 or 16. If you do not know your ring size, ask some jeweler to measure it for you or go online and look for some how-to-measure-size guide.

Blue diamonds and their significance:
Diamonds are precious; colored diamonds are extraordinarily expensive; and blue diamonds are royal rich and luxurious. They match blue sapphires but have outstanding brilliance and durability. Blue diamonds come in different shades ranging from light sky blue to deep velvet blue color. You should go for the one that matches your skin tone. Remember, whichever diamond you select, it should not reflect any purple, green or yellow hues.
Picking blue diamond for ring size 9:
As ring size 9 is for quite fatter and bigger hands, if you go for a solitaire blue diamond ring, make sure your diamond is big enough to match your fingers. An almost 2 ct diamond would do well for size 9. Different styles of rings can alter the diamond size. For example, if you are going for a blue diamond eternity ring, you would require several smaller diamonds and the total carat weight might come out to be 0.30 for size 9. Choose the ring style, diamond carat weight and ring band width carefully for your fingers.
