Welcome to SuchenGems!
Sphene, also known as titanite, is a gemstone characterized by its brilliant fire, which can exceed that of a diamond, and its high dispersion. It is a calcium titanium silicate mineral that comes in colors like yellow, green, brown, and red. While its optical properties are stunning, sphene is relatively soft with a Mohs hardness of 5 to 5.5 and is often found with inclusions, making eye-clean and flawless specimens rare and valuable.
Physical and chemical properties
Chemical Formula:
CaTiSiO5
CaTiSiO5
(calcium titanium silicate)
Hardness: 5 to 5.5 on the Mohs scale
Color: Ranges from yellowish-green, green, and orange-brown to red and colorless, with chrome-green being particularly rare
Refractive Index: 1.843 to 2.110
Cleavage: Has good cleavage, is brittle, and has a high birefringence
Luster: Adamantine luster, meaning it has a diamond-like shine
Dispersion: High dispersion, which causes it to separate light into a spectrum of colors, creating "fire"
Pleochroism: Exhibits pleochroism, meaning it displays different colors when viewed from different angles
Appearance and value
Sphene is prized for its exceptional brilliance and fire, sometimes compared to or even exceeding that of a diamond.
The most desirable colors are bright green, particularly yellow-green and chrome-green.
Due to its softness, it is not recommended for daily wear in rings, but is suitable for earrings, pendants, or brooches if set properly.
Origin
Sphene crystals are typically found in metamorphic and igneous rocks like gneiss, schist, and granitic pegmatites.
Major sources include Brazil, Burma, India, Kenya, Madagascar, Mexico, Austria, Sri Lanka, and the USA.

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.
