Andesine occurs in various colors, from red and honey-red to orange, yellow, champagne, and green. The semi-precious gemstone often shows greenish hints and a faint metallic shiller (or labradorescence). Some are even color-changing, displaying different hues under different types of lighting.

All plagioclase feldspars are composed of albite (sodium aluminum silicate) and anorthite (calcium aluminum silicate) in varying compositions. Other plagioclase minerals include bytownite, moonstone, oligoclase, and spectrolite, among others.

Andesine has a ratio of 30 to 50 percent anorthite to 50 to 70 percent albite, so some mineralogists classify it as an albite variety.

In terms of habits, andesine rarely forms as crystals; when it does, they’re usually small. Andesine crystals often display Albite, Pericline, and Carlsbad twinning. Usually, andesine is found in granular or massive habits.

Here’s an overview of andesine’s mineral traits:

  • Chemical formula: (Na,Ca)[Al(Si,Al)Si2O8]

  • Mohs hardness: 6 to 6.5

  • Color: White, gray, green, yellow, red, orange, pink, champagne, golden

  • Crystal structure: Triclinic

  • Transparency: Transparent to opaque

  • Refractive index: 1.56 to 1.57; Increases with higher calcium content

  • Density: 2.66 to 2.68; Increases with higher calcium content

  • Cleavage: Perfect on {001}, good/distinct on {010}

  • Fracture: Subconchoidal or irregular/uneven

  • Streak: White

  • Luminescence: Fluorescence (weak); Red, blue, pink, yellow, or yellowish-brown in SW-UV, violet in MW-UV, and yellowish-white, orange, or orange-red in LW-UV

  • Birefringence: 0.009

  • Pleochroism: None

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
