In feng shui, the number 11 is often considered a special number because it represents a blend of spiritual strength and the positive meaning of the number 1. The number 1 symbolizes a favorable beginning and brings many good omens. The doubling of the number 1 to form 11 not only means double luck but is also a symbol of sublimation and success.
Meanwhile, in Sino-Vietnamese, the number “5” is pronounced “Ngũ,” and this pronunciation is similar to the word “Phúc.” Therefore, people in the past believed that this number symbolized the “Five Blessings,” including Wealth, Nobility, Longevity, Health, and Peace. From that, the presence of the number 5 is believed to bring luck and prosperity.
From this, people have passed down the belief that those who own objects related to both of these numbers, such as an 11.5 ly diamond, may have a fulfilling life with double luck and positive growth. The meaning of an 11.5 ly diamond is harmony and balance, creating favorable conditions for new beginnings, success, and prosperity in every aspect.
