Birthstones and gemstones by sign
Gemstone lore appears in Western birthstone charts, Jyotish ratna practice, and Chinese zodiac gift culture. Today's Horoscope publishes dedicated pages for Western sun signs, Vedic rashis, and Chinese animals, the three traditions with widely circulated stone associations.
We do not cover Tibetan, Celtic, Mayan, or Akan gemstone systems here because widely accepted historical mappings are thin compared with the three clusters below. Read what are birthstones? for a cross-tradition overview and limits.
Western gemstones
Western birthstone lists match sun signs and calendar months to gems that jewelers have sold for years. Think diamond for Aries and April, emerald for Taurus, and so on. Shops also sell alternate stones when the "official" gem is too expensive.
Vedic gemstones
In Jyotish (Vedic astrology), certain gems are linked to planets and rashis. Coral often shows up with Mars, pearl with Moon, yellow sapphire with Jupiter, though teachers disagree on weight, metal, and whether you should wear a stone at all.
