What Exactly Is Tanzanite?

Tanzanite is a blue-to-violet variety of the mineral zoisite. One reason it’s so captivating is its natural “color play” — many stones show different hues depending on the angle and lighting.

Pricing varies widely based on color, clarity, size, and cut. (In other words: there isn’t one “average” price that stays accurate for long.)

  • Mineral Family: Zoisite (a variety known as tanzanite)
  • Color Range: Blue, violet, purple (often with subtle color zoning)
  • Hardness: 6–7 on the Mohs Hardness Scale
  • Rarity Note: Found in one small region of Tanzania — limited supply

Tanzanite Color, Quality & What to Look For

Tanzanite is famous for its blue-violet range. Many stones also show pleochroism (different colors from different angles), which gives tanzanite depth and personality.

  • Blue-Violet: The most classic and most sought-after look
  • Violet-Purple: Softer, romantic tones that still feel luxurious
  • Color Zoning: Natural bands or areas of color inside the stone

When evaluating tanzanite, jewelers often consider:

  • Color: Rich saturation without looking gray or washed out
  • Clarity: Eye-clean stones are typically preferred
  • Cut: A well-cut stone improves sparkle and helps “show” the color
  • Treatment: Heat treatment is common and generally accepted

Symbolism & Meaning of Tanzanite

Tanzanite is often associated with transformation, intuition, and a calm, centered sense of clarity. Its blue-violet palette feels both modern and timeless — a beautiful choice for milestones, anniversaries, and meaningful personal gifts.


Is Tanzanite Durable for Daily Wear?

Tanzanite can absolutely be worn often — but it’s best worn with a little extra care. At 6–7 on the Mohs scale, it’s softer than sapphire and diamond, so it’s more vulnerable to scratches and impacts.

  • Avoid contact with harsh chemicals (cleaners, chlorine, etc.).
  • Remove jewelry during strenuous activities and heavy lifting.
  • Store away from harder gemstones (like diamonds, sapphires, and topaz).
  • If you love rings for everyday wear, consider protective settings and mindful wear habits.

How to Clean & Care for Tanzanite Jewelry

Cleaning Tips

  • Use warm water, mild soap, and a soft brush.
  • Rinse thoroughly and dry with a lint-free cloth.
  • If you’re unsure about your stone’s setting or treatment, choose the gentlest cleaning method.

Avoid

  • Harsh chemicals
  • Steam cleaning and extreme heat
  • Ultrasonic cleaners (best avoided for tanzanite)

Storage

  • Store in a soft pouch or lined box.
  • Keep separate from harder gemstones to prevent scratching.

Styling Tanzanite – Cool, Elegant & Modern

Tanzanite pairs beautifully with both bright metals and warm tones — it’s one of those gemstones that can look refined, edgy, or romantic depending on the design.

  • Argentium Silver: Clean, modern, and makes blue-violet tones pop (a MONOLISA signature look)
  • 14k Gold: Adds warmth and contrast for a richer, luxe feel
  • Minimal Settings: Let the color and pleochroism do the talking
