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.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
