Opal dot spiral 3D geometric pattern borosilicate glass pendant

This is a single handmade pendant made of borosilicate glass (heat-resistant glass). This is a glass piece with an opal in a three-dimensional geometric pattern. When light shines on the glass, the colors of the pattern appear vivid. When the opal is exposed to light, it reflects the light with a play of colors. The loop through which the string passes is made of transparent glass. The back side of the glass is made of transparent red-colored glass. *Notes about the design -There are small air bubbles near the opal. This piece is carefully handmade, but the shape, pattern, and position of the opal are not completely symmetrical or centered. Please check the photos and video of the piece. There is also a video of this piece, so please check it out. https://www.youtube.com/shorts/leQ_9OYZskM Length (including string threading point) approx. 3.2m Width (maximum point) approx. 2.5cm Thickness approx. 1.8cm Weight approx. 16g The opal used is an opal made with specialized technology that will not break even in high-temperature environments where heat-resistant glass melts. This is a one-of-a-kind glass pendant made by hand, melting heat-resistant glass at temperatures of over 2500 degrees with an oxygen burner using oxygen. The heat-resistant glass used as the material is harder and more transparent than ordinary glass, and is characterized by its anti-oxidation properties, which make it less likely to discolor or deteriorate, and its light weight. It is mainly used in the fields of physics, chemistry, and optics. The pendant string will be delivered in the same condition as the work image. (Brown wax cord, Mitsuyori string) The string has an adjuster, so you can adjust the length of the string by sliding the adjuster. The color of the string can be changed to beige or other colors.
