Spinel is a crystalline mineral, often found in a variety of colors, and prized as a gemstone. Chemically, it's a magnesium aluminum oxide (MgAl2O4) and is known for its hardness and durability, ranking 8 on the Mohs scale. Spinel is frequently mistaken for rubies and sapphires, especially the red and blue varieties, and can be found in igneous and metamorphic rocks.
Here's a more detailed description:
Appearance:
Color: Spinel exhibits a wide range of colors, including red, pink, lavender, violet, blue, green, brown, and black.
Crystal Structure: It typically forms in the isometric (cubic) system, often as octahedral crystals.
Luster: Spinel has a vitreous (glassy) luster.
Transparency: It can be transparent to translucent.
Chemical and Physical Properties:
Chemical Formula: MgAl2O4.
Hardness: 8 on the Mohs scale.
Refractive Index: 1.718.
Specific Gravity: 3.60.
Cleavage: Spinel has no true cleavage, meaning it doesn't break along specific planes.
Single Refractive: It is singly refractive, meaning light doesn't split into two rays when passing through it.
Occurrence:
Spinel is found in various geological settings, including:
Igneous rocks: Rocks formed from cooled magma or lava.
Metamorphic rocks: Rocks altered by heat and pressure.
Contact metamorphic limestone deposits: Limestone altered by the heat of nearby magma.
Gravel deposits: Often found alongside corundum (ruby and sapphire).
Localities: Spinel is found in many locations worldwide, including Myanmar, Sri Lanka, Tanzania, and others.
Historical Significance:
Spinel has been historically confused with rubies and sapphires due to its similar appearance.
Some famous historical gems, like the "Black Prince's ruby" in the British Crown Jewels, are actually spinel.

Perché gli utenti superano se stessi?
Quando viene fatta un'offerta, questo è l'importo massimo che una persona è disposta a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto dell'offerente, aumentando gradualmente l'offerta fino al massimo per mantenere la sua posizione di miglior offerente.
Quando c'è un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente piazzando offerte per l'offerente in base alla sua offerta massima. Questo potrebbe sembrare come se gli offerenti stessero superando se stessi, ma è semplicemente il risultato del sistema che aggiorna l'offerta per riflettere il limite massimo degli offerenti.
