Welcome to SuchenGems!
Sphene, also known as titanite, is a rare calcium titanium silicate mineral prized for its exceptional brilliance and fire, often exceeding that of diamonds, and is characterized by its wedge-shaped crystals derived from the Greek word "sphenos". It exhibits a wide range of colors, including yellow, green, brown, red, orange, pink, and black, with green and yellow-green varieties often being the most valuable due to their rarity and appeal.
Key Characteristics and Properties:
Chemical Composition:
A calcium titanium silicate (CaTiSiO5) with trace impurities of iron and aluminum, and sometimes rare earth metals.
Appearance:
Crystals are typically wedge-shaped and can be found in various colors, with a resinous to adamantine luster.
Dispersion:
Sphene has a very high dispersion (0.051), meaning it significantly refracts white light into spectral colors, creating a brilliant "fire".
Hardness:
It is relatively soft, scoring 5.0-5.5 on the Mohs hardness scale, making it somewhat fragile for everyday wear without careful setting.
Transparency:
Jewelry-grade sphene is transparent, though it can also occur as opaque or translucent specimens.
Trichroism/Color Change:
Some specimens can exhibit dichroism or even trichroism, displaying different colors when viewed from different angles. Rare specimens may even show color change under different lighting conditions.

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.
