Most people know their birthstone by month, but there is an older and equally charming tradition: a lucky stone for the weekday you were born. Each day of the week has been linked for centuries to a celestial body — the Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the Sun — and each of those carries its own gemstones, colors, and themes. Finding your weekday stone is simple, fun, and surprisingly personal.
Unlike monthly birthstones, which are shared with millions of people born in the same month, your weekday stone adds a second layer to your story. Many people combine both: a monthly birthstone for identity and a weekday stone for everyday luck. You can check your monthly stone in our birthstones by month chart and then find your weekday match below.
How the Weekday Tradition Works
The names of the days still carry their planetary origins in many languages: Monday is the Moon’s day, Saturday is Saturn’s day, and Sunday is the Sun’s day. In English, Tuesday through Friday preserve Norse versions — Tyr, Odin (Woden), Thor, and Frigg — but in astrological tradition they correspond to Mars, Mercury, Jupiter, and Venus. The history of the seven-day week shows how widely this system spread across cultures.
In Vedic astrology and Thai tradition — where each weekday even has its own lucky color — gemstones are assigned to these planetary rulers. The list below blends those widely used correspondences into one practical guide. Treat it as tradition and inspiration: wear the stone as a reminder of the quality its planet is believed to represent.
Monday to Wednesday: Moon, Mars, Mercury
Monday (Moon) — Pearl and Moonstone. Monday-born people are often described in folklore as sensitive, intuitive, and family-oriented. Moonstone is traditionally associated with calm emotions and intuition, while pearl symbolizes serenity. An AVENSU moonstone bracelet is a gentle everyday choice for Monday birthdays. Learn more in our moonstone meaning guide.
Tuesday (Mars) — Ruby and Red Coral. Tuesday carries the energy of Mars: courage, drive, and action. Ruby is traditionally linked to vitality and confidence, and red stones in general are believed to suit people who lead and compete. If ruby is beyond budget, garnet offers a similar deep-red look at a friendlier price.
Wednesday (Mercury) — Emerald. Wednesday-born people are linked to Mercury, planet of communication, trade, and quick thinking. Emerald is the classic Mercury stone in Vedic tradition, believed to support clear speech and good judgment in business. Green aventurine and jade are popular everyday alternatives; our green aventurine meaning guide explains its luck associations.
Thursday to Sunday: Jupiter, Venus, Saturn, Sun
Thursday (Jupiter) — Yellow Sapphire and Citrine. Jupiter is the planet of expansion, wisdom, and good fortune, so Thursday stones are among the most explicitly luck-focused. Yellow sapphire is the traditional choice in Vedic practice; citrine, traditionally associated with optimism and abundance, is the accessible alternative many people wear daily.
Friday (Venus) — Diamond and White Stones. Friday belongs to Venus, planet of love, beauty, and art. Diamond is the classic Venus stone, but clear quartz and white sapphire carry the same bright, clear symbolism at everyday prices. Our clear quartz meaning guide shows why clear quartz is called the most versatile stone. Rose quartz also fits Friday’s Venus theme for those who prefer pink; see our rose quartz meaning guide.
Saturday (Saturn) — Blue Sapphire and Amethyst. Saturn represents discipline, patience, and long-term reward. Blue sapphire is its traditional stone, believed to reward steady effort. Amethyst and black obsidian are common alternatives; obsidian’s protective tradition is covered in our obsidian meaning guide.
Sunday (Sun) — Ruby and Sunstone. Sunday-born people get the Sun: vitality, visibility, and leadership. Ruby appears again here as the Sun’s classic stone in Vedic tradition, while sunstone and amber-toned citrine offer warm, golden alternatives. An AVENSU citrine or sunstone-style bracelet makes a bright Sunday gift. Browse options in the AVENSU shop.
Combining Your Weekday Stone with Other Traditions
Your weekday stone does not replace your other stones — it layers with them. A common approach is a bracelet that pairs your weekday stone with your zodiac stone; our element guides to lucky stones for Fire signs and the other elements make that easy. Others combine the weekday stone with a stone for a current goal, such as green aventurine for a new business or amethyst for calmer sleep routines.
For gemstone facts such as hardness and durability — useful before choosing a daily-wear stone — the Gemological Institute of America (GIA) is the standard reference. Softer stones like pearl are better kept for occasional wear, while quartz-family stones suit daily bracelets well.
