Sphene, also known as titanite, is a brilliant and colorful gemstone prized for its exceptional fire—the dispersion of light into a rainbow of colors, often surpassing that of diamond. Here's a brief description:
Sphene (Titanite) Overview
Color: Most commonly green, but also occurs in yellow, brown, reddish, or even black. Vivid green and yellow-green stones are the most valued.
Luster: Adamantine to sub-adamantine (very shiny and sparkly)
Hardness: 5–5.5 on the Mohs scale
Crystal System: Monoclinic
Refractive Index: 1.84–2.10 (high, contributing to its brilliance)
Dispersion: 0.051 (very high; more fire than diamond)
Transparency: Transparent to translucent
Composition: CaTiSiO5 (calcium titanium silicate)
Notable Characteristics
Fire & Brilliance: Due to its high dispersion and refractive index, sphene displays spectacular fire.
Birefringence: Strong double refraction causes a slightly "blurry" look when viewed under magnification.
Rarity: Sphene is relatively rare in gem quality, making it a collector's stone.
Care
Because of its relatively low hardness, sphene is best suited for pendants, earrings, or collector pieces rather than rings worn daily. Avoid harsh knocks or abrasive cleaning.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
