Zodiac signs and their Roho stones
Each Roho zodiac necklace is a double-sided 925 silver constellation coin. The stars are lab-grown CVD diamonds, clearly labelled, and the brightest star holds the sign's stone, which follows the month in which most of the sign falls. Dates use the tropical zodiac and can shift by a day from year to year.
