centuries, sapphire (mainly blue) was considered the birthstone of April. However, in the 16th century in Poland, Jewish mystics and jewelers introduced the tradition of wearing birthstones, and diamond replaced sapphire for April. This shift was later reinforced in 1912, when the American National Retail Jewelers Association officially assigned diamond to April and moved sapphire to September, largely for commercial reasons—to ensure a mix of high-end and affordable stones for each month.
From an astrological perspective, diamond as April’s birthstone is questionable. In Western astrology, most of April falls under Aries, where the Sun is exalted. Since diamond is a Sun stone, wearing it could intensify an already dominant energy. In Vedic astrology (Jyotish), April is divided between Pisces (ruled by Jupiter) and Aries (ruled by Mars), making neither diamond (Venus) nor sapphire (Saturn) a natural fit.
Thus, the choice comes down to sapphire, based on Christian tradition, or diamond, as defined by the American Jewelers Association. The decision is yours.
