Cobalt spinel is a rare and prized variety of spinel gemstone known for its vibrant blue hue, often rivaling the color of fine sapphires. This intense blue color is primarily due to the presence of cobalt ions within the crystal structure. Natural cobalt spinel can range in color from a rich, saturated blue to lighter shades with hints of violet.
Spinel is a mineral that comes from Afghanistan, Brazil, Burma (Myanmar), Cambodia, Kenya, Russia, Sri Lanka, Tanzania, Thailand and Vietnam. Spinel is a durable gemstone with a hardness of 8.0 on the Mohs Hardness Scale. Spinel is cut in many shapes and sizes.

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.
