5.45CT Natural Katlang Topaz stone
Weight:(5.45)CT
Stone:(Topaz)
Origin:( Pakistan From Katlang)
Treatment: Natural Topaz( Not radiated)
Topaz is a silicate mineral made of aluminum and fluorine with the chemical formula Al2SiO4(F, OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden brown to yellow-orange.[7] Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.
Topaz is a nesosilicate mineral, and more specifically, an aluminosilicate mineral.[9] It is one of the hardest naturally occurring minerals and has a relatively low index of refraction. It has the orthorhombic crystal system and a dipyramidial crystal class.[10]
It occurs in many places in the world. Some of the most popular places where topaz is sourced are Brazil and Russia.[7] Topaz is often mined in open pit or alluvial settings.

Perché gli utenti superano se stessi?
Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
