Always consider to use high quality gold for your ring
. Gold with different qualities like 10k, 14k, 18k, and 24k are found in the market. 24k gold is the purest among all but may not be suitable for your ring as it is soft and scratches or wears in a very short time. 14k gold is harder but 18k is perfect for your ring. Never forget to check the quality of gold you are going to buy. So, check whether the gold is hallmarked or not. Blue sapphire suits best in both white and yellow gold. After the selection of gold is done, design of the blue sapphire gold ring is another thing you need to consider. Classic design may be the best choice for your ring.
