Ring

Abstract

The first portion (P 1 ) of the band ( 1 ) of the ring ( 10 ) has the first ditch portion ( 2 ) into which the first stone ( 4 ) that is a diamond is fitted. On the other hand, the second portion (P 2 ), which faces the first portion (P 1 ), has the second ditch portion ( 3 ) into which the second stone ( 5 ) that is a blue sapphire or the like is fitted. In the first usage pattern of the ring ( 10 ), the ring ( 10 ) is worn so that the first stone ( 4 ) is on the back of the hand. In this condition, the second stone ( 5 ) on the palm side does not come in contact with any part of the hand. The second usage pattern where the second stone ( 5 ) is on the back of the hand is realized by rotating the band 1 approximately half-turn. Thus, the single ring can be used in two different ways without making the wearer feel a sense of incongruity.
