{"title":"Saphirs taille trilliant – Pierres sur papier triangulaires pour créateurs","description":"\u003cp\u003eLa taille trilliant (ou trillion) est l'une des formes les plus audacieuses de la taille : un contour triangulaire à trois côtés égaux, des facettes brillantes rayonnant depuis le centre et une présence que peu de tailles égalent. Le saphir trillion a une allure moderne et géométrique, avec une surface vue de dessus qui paraît nettement plus grande que son poids ne le laisse supposer.
