Tourmaline is extremely popular among collectors and is a well-known gemstone. It is the most multicolored mineral type known, occurring in virtually every color of the spectrum. Individual stones are often multicolored and are unsurpassed in their beauty. The color of some Tourmaline can be enhanced through Heat treatment. Some greenish stones can be made deep green, some brownish-red stones can be made red, and some light pink stones can be made colorless through heating. Tourmaline has many interesting optical properties. Many green and blue specimens are strongly pleochroic. Indicolite is one of the most valuable and collectible of all elbaite Tourmalines, with hues spanning from lighter to deep, intense blues. Cutting indicolite can be a task for even the most skilled of cutters, as it is strongly Pleochroic and appears darker when viewed down the crystal. This factor must be taken into consideration when cutting, as a loss of transparency and brilliance can occur in darker specimens.

White crystal slightly off the table was well concealed in all the videos and pictures posted but the sapphire has great color. Thanks for the prompt shipping, received in a week's time from payment via Registered Mail.
Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'un utilisateur est prêt à enchérir pour le produit. Notre système enchérira ensuite automatiquement au nom de cet utilisateur, augmentant progressivement l'enchère pour maintenir sa position d'enchérisseur le plus élevé, jusqu'au maximum spécifié.
Lorsqu'il y a une icône indiquant "Enchère automatique", cela signifie que notre système place activement des enchères pour l'utilisateur en fonction de son enchère maximale. Cela peut donner l'impression que les utilisateurs surenchérissent eux-mêmes, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des utilisateurs.
