For those born in the month of March, the official gemstone is the Aquamarine. It can range in color from a very pale shade, almost colorless, which is also the most valuable, to a most sought-after deep-blue aqua.
English Mastiff is the largest dog breed in the world by considering the mass. This breed has an average weight of 68-110 kg and shoulder height of 27-33 inches. On 26th September 1981 the Guinness book of world records recognized an old English Mastiff named Zorba as the heaviest and longest dog in the world.
Considered the largest of all dog breeds, the English Mastiff's name seems to fit its best descriptions: massive. This giant dog breed is all brawn and power on the outside, but deep down it is a lovable, mushy companion--and often a bit of a couch potato! These dogs can top the scales at 220 pounds and be 30 or more inches tall. However, it looks like a large percentage of the weight is in their huge heads.
