[On sale August 8th, 10 PM JST] Mexican Cantera Opal 5.079 ct Loose Stone (Filled) with Japan-Germany Gemstone Appraisal

Opal is a gemstone characterized by iridescent flashes of light. There are several types of opal, and among them, Cantera Opal is popular with collectors. Many enthusiasts are drawn to it as it evokes the dynamism of the Earth, and it is a gemstone that can be fully enjoyed even in its loose form. Cantera opal naturally has many 'can' (holes or cavities). Photography is done using a penlight.

This is a Cantera Opal from Mexico. Its beautiful play-of-color is captivating, and it comes with an appraisal report from the Japan-Germany Gemological Institute. This Cantera Opal has undergone a rare filling treatment. This is a reinforcement treatment where resin is filled to prevent the separation of the play-of-color area from the host rock and to enhance durability, and this fact is noted in the appraisal report.
