Weekday stones are gemstones assigned to each day of the week based on Vedic astrology, also called Jyotish. In this tradition, every weekday is governed by a planet known as a graha, and each graha has a corresponding ratna, or gemstone, that is said to channel its qualities. The Navaratna system groups nine such gems together as a sacred set: ruby, pearl, red coral, emerald, yellow sapphire, diamond, blue sapphire, hessonite, and cat's eye. Wearing the stone linked to a particular weekday and its ruling planet is a centuries-old practice meant to support the wearer's energy, focus, and well-being in ways aligned with that planet's influence.
The 7 Weekday Stones
Sunday — Sun (Surya) — Ruby
Sunday belongs to Surya, the Sun, the source of vitality and authority in Vedic astrology. The traditional stone is ruby, a red variety of corundum with a Mohs hardness of 9 and colors ranging from pinkish red to deep pigeon blood. Since fine natural rubies can be costly, red garnet (Mohs 7 to 7.5) and red spinel serve as accessible substitutes that keep the warm red tone associated with the Sun. Wearing a Sunday stone is believed to support confidence, leadership, clarity of purpose, and good health. The stone is often set so it touches the skin. Browse our Sunday stones jewelry collection for rings and pendants in these warm red gems.
Monday — Moon (Chandra) — Pearl
Monday is ruled by Chandra, the Moon, which governs emotions, intuition, and the mind. The classical stone is natural pearl, organic in origin with a Mohs hardness of only 2.5 to 4.5, prized for its soft white luster. Because fine saltwater pearls command high prices, moonstone (Mohs 6 to 6.5) with its blue or white adularescent glow is a popular modern substitute, as is cultured freshwater pearl. Wearing a Monday stone is said to support emotional balance, restful sleep, and a sense of calm. Pearls suit silver settings well and are often worn in rings or pendants. See our Monday stones jewelry selection for pearl and moonstone pieces.
Tuesday — Mars (Mangal) — Red Coral
Tuesday is governed by Mangal, the planet Mars, associated with courage, drive, and physical strength. The traditional stone is red coral, an organic gem formed from marine coral skeletons, with a Mohs hardness around 3 to 4 and colors from orange-red to oxblood. Carnelian (Mohs 6.5 to 7) offers a budget-friendly substitute in a similar warm red-orange range and is more durable for daily wear. A Tuesday stone is believed to support stamina, motivation, and protection against setbacks. Red coral is often set in silver or copper and worn on the ring finger. Explore our Tuesday stones jewelry range for red coral and carnelian options.
Wednesday — Mercury (Budh) — Emerald
Wednesday is the day of Budh, Mercury, the planet of intellect, speech, and communication. The assigned stone is emerald, a green variety of beryl with a Mohs hardness of 7.5 to 8 and color ranging from light spring green to deep forest green. Fine emeralds can be expensive due to natural inclusions, so green tourmaline, peridot, and tsavorite garnet work well as alternatives in a similar green family. A Wednesday stone is said to support clear thinking, learning, negotiation, and adaptability. Emerald suits both silver and gold and is often worn on the little finger.

Thursday — Jupiter (Guru) — Yellow Sapphire
Thursday belongs to Guru, Jupiter, the planet of wisdom, teachers, and growth. The traditional stone is yellow sapphire, a yellow variety of corundum with a Mohs hardness of 9 and colors from pale lemon to rich golden. Since yellow sapphire of good clarity is pricey, citrine (Mohs 7) and yellow topaz are common affordable substitutes that share the warm golden hue. Wearing a Thursday stone is believed to support learning, ethical decision-making, prosperity, and family well-being. It is often worn on the index finger, the finger associated with Jupiter. See our Thursday stones jewelry collection for yellow sapphire, citrine, and topaz pieces.
Friday — Venus (Shukra) — Diamond
Friday is the day of Shukra, Venus, the planet linked with love, art, beauty, and partnerships. The classical stone is diamond, the hardest natural gem at Mohs 10, usually colorless or near-colorless. Given the cost of fine diamonds, white sapphire (Mohs 9) and white topaz (Mohs 8) are practical substitutes with strong brilliance, and white zircon is another option. A Friday stone is said to support harmony in relationships, creativity, and refinement of taste. White gems suit both silver and white gold settings. Browse our Friday stones jewelry for white sapphire, topaz, and other Venus-linked gemstones.
Saturday — Saturn (Shani) — Blue Sapphire
Saturday is ruled by Shani, Saturn, the planet of discipline, patience, and long-term work. The traditional stone is blue sapphire, a blue variety of corundum with a Mohs hardness of 9 and colors from cornflower to royal blue. Because fine blue sapphire is expensive and Vedic tradition treats it as a strong stone best tested before regular wear, iolite, blue spinel, and amethyst are sometimes suggested as gentler alternatives. A Saturday stone is believed to support focus, endurance, and protection from obstacles. It is often worn on the middle finger.

How to Wear Weekday Stones
Setting choice matters in Vedic practice. Silver is generally preferred for cool or lunar stones such as pearl, moonstone, and blue sapphire, while gold is favored for warm or solar stones like ruby, yellow sapphire, and red coral. The stone should ideally touch the skin through an open back in the setting, allowing direct contact. Finger placement follows the planet: ring finger for Sun and Mars, little finger for Mercury, index finger for Jupiter, middle finger for Saturn, and various options for Moon and Venus. Some wearers also match the stone to its related chakra, with ruby linked to the heart and solar plexus area and pearl linked to the throat and heart.
You can wear more than one weekday stone, though most practitioners suggest starting with a single gem and observing how it feels over several weeks. Avoid pairing stones whose ruling planets are considered unfriendly in Jyotish, such as ruby with blue sapphire, until you have guidance from someone familiar with your chart. The traditional time to begin wearing a new stone is during the bright half of the lunar month, on the weekday of its ruling planet, often in the morning hours. Cleanse the piece with clean water before first wear, and clean the setting regularly to keep the gem in contact with the skin.
Frequently Asked Questions
Do I need to wear a weekday stone every day?
No. Some wearers rotate stones by weekday, putting on ruby for Sunday, pearl for Monday, and so on. Others choose a single stone matched to their ruling planet in their birth chart and wear it daily. Both approaches are part of the tradition, and you can pick whichever fits your lifestyle and jewelry collection.
What is a good affordable substitute for blue sapphire?
Iolite is the most common substitute for blue sapphire, offering a violet-blue color at a fraction of the price. Blue spinel and tanzanite are other options in the blue range, and amethyst is sometimes suggested when a gentler stone is preferred. These alternatives keep the cool blue tone associated with Saturn without the cost of fine sapphire.
Can I wear sterling silver with weekday stones?
Yes. Sterling silver suits cool-toned stones such as pearl, moonstone, emerald, diamond substitutes, and blue sapphire very well. For warm stones like ruby, red coral, and yellow sapphire, gold is the traditional preference, though many modern wearers choose silver for consistency across their jewelry. The most important factor is that the gem remains in good contact with the skin.
How do weekday stones differ from birthstones?
Birthstones in the Western system are tied to the calendar month of your birth and were standardized by jewelers in the early twentieth century. Weekday stones come from Vedic astrology and are tied to the planet ruling each day of the week. The two systems overlap at times, for example ruby appears in both July birthstones and Sunday stones, but they draw on different traditions and logic.
