<Characteristics of Pure Gold>

A crystal of gold atoms, pure gold, the highest quality. As far back as the 10th century BC, pure gold was used lavishly in the temple built by King Solomon. It is also said that gold was used for Buddhist statues and ritual implements adorned with pure gold. In medieval Europe, the work of goldsmiths led to its use in crowns and jewelry. Pure gold has captivated people throughout history with its beauty and aura. Historically, pure gold has been used in treasures, crafts, jewelry, and architecture since ancient times.

① Purity
K24 = 99.9% pure gold
K18 = 75% pure gold
K10 = 42% pure gold

② Specific Gravity
K24 = Specific gravity: 19.13-19.51
K18 = Specific gravity: 14.84-16.12
K10 = Specific gravity: 11.42-13.09
Silver 925 = Specific gravity: 10.35

The higher the purity of gold, the heavier it is. K24 pure gold is approximately twice as heavy as silver. The atomic weight, which represents the relative ratio of atomic mass, is 197 for gold, 108 for silver, and 64 for copper. Gold is about twice as heavy as silver and three times as heavy as copper.

③ Strength
K24 = Soft
K18 = Practical hardness
K10 = Quite hard
Silver 925 = Fairly soft

K24 pure gold is soft, so it will dent or deform if handled roughly. It is suitable for those who can enjoy the "time" and aging of the product, cherishing it like a dog, cat, or leather product. Bangles and rings will be delivered with a practical thickness that resists deformation.

④ Color Change
K24 = Does not tarnish
K18 = Tarnishes
K10 = Tarnishes
Silver 925 = Tarnishes

Pure gold does not tarnish, so it never loses its beauty. This is why pure gold has been used in treasures, crafts, jewelry, and architecture since ancient times.
