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
Luster: Sub-vitreous or pearly
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
Dispersion: Weak to none
Optical effects: Sometimes color-changing

なぜユーザーは自分自身を上回る入札をするのでしょうか?
入札する場合、これはユーザーが製品に入札する意思のある最大金額です。その後、当社のシステムがそのユーザーに代わって自動的に入札し、最高入札者としての地位を維持するために、指定された最大値まで入札額を段階的に引き上げます。
「自動入札」を示すアイコンがある場合、システムが最高入札額に基づいてユーザーに積極的に入札していることを意味します。これは、ユーザーが自分自身を上回って入札しているように見えるかもしれませんが、ユーザーの上限を反映するためにシステムが入札を更新した結果にすぎません。
