Jewelry Design Pure Infinity Pendant by Bettina Gomez-Latus The pendant is made of 18K red gold and a topaz with 92.14 ct. The gemstone setting and the suspension are made of a single wire. It runs from narrow to wide in an infinite loop without touching at the crossing point. The mounting of the pendant is slanted, however this allows the jewel to hang straight on a chain without tilting back or forth.
