People in the Ancient Society of Korea liked golden earrings. The Royal Family or the nobility wanted to make more splendorous golden earrings in order to display their high-ranking positions. However, appearances or production methods of golden earrings differ a little by countries, for example, Goguryeo, Silla, Baekje, Gaya, etc. Therefore, by closely examining articles discovered from tombs, we can know which country they were from. In particular, earrings of Goguryeo and Silla are similar to each other while those of Baekje and Gaya are similar. This would be closely related with political relationships between the two countries. The shape of golden earrings in the middle of the $5^{th}$ century A.D. is relatively simple. However, since the latter half of the $5^{th}$ century, golden earrings in the Ancient Society of Korea changed in the direction of long length or significantly splendorous surface decoration. Accordingly, we can estimate the period of production by analyzing golden earrings discovered from a tomb. In addition, the above trend was common all the earrings in the Ancient Society of Korea, which implies that each nation closely exchanged reciprocally at that time.
