Blue Diamond is considered to be one of the most expensive and rarest types of Diamonds. This blue gemstone came to market in huge demand most probably after it was featured in the Super Hollywood movie “Titanic” where Rose was seen wearing it and later threw it in the sea as gratitude of love to Jack. A perfect gemstone to gift to your beloved on your 60th anniversary helps in strengthening the will power and inspires to take better care of our health.
