boroccus micro opal blue silver fume 3D geometric borosilicate glass pendant.

This is a handmade pendant made of borosilicate glass (heat-resistant glass). This glass piece features a three-dimensional pattern with many micro opals studded around a pattern created using silver. The loop through which the string passes is made of transparent, dark purple-colored glass. (It looks almost black.) The back side is made of black glass. *Points to note about the design of the piece. (This is a long text, but please read the text below when considering purchasing.) -There are air bubbles along with the micro opals in the areas where the micro opals are studded. There are about two air bubbles that can be seen if you look closely at the top of the pattern in the center. One of these bubbles can be confirmed as an air bubble, but the other bubble is very small and cannot be seen normally, but when exposed to strong light such as sunlight, the air bubble appears as a small black dot due to the white-blue pattern behind it. This black dot is near the surface of the glass, so we tried to remove the air bubble, but we were unable to remove it even after removing the glass on the surface. In order to prevent discoloration and deformation of the pattern, we decided to list it as it is. This black air bubble can be seen slightly to the lower right of the center of the pattern. The last product image is an introduction photo that focuses on the air bubble, but the air bubble is very small so it is not in focus. The price has been set taking these points into consideration. Size varies depending on the work. Please also check the size of the work. Size of the work Length (including the string threading part) approx. 3.3 cm Width (maximum part) approx. 2.5 cm Thickness approx. 2.4 cm. Weight approx. 21g (including the string part) Because it is a handmade work, the shape is not a perfect circle or sphere, and the pattern is not symmetrical or centered. There is also a video of this work, so please check it out. https://www.youtube.com/watch?v=f_NKs9t1c4g This is a one-of-a-kind glass pendant made by hand by melting heat-resistant glass at a temperature of over 2000 degrees using an oxygen burner. The heat-resistant glass used in the material is harder and more transparent than ordinary glass, and is lightweight and has antioxidant properties that make it less likely to discolor or deteriorate. This glass 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. It is a three-stranded string of black wax cord. The string has an adjuster, so you can slide the adjuster to adjust the length of the string steplessly. The color of the string can also be changed to navy or brown. Please let us know at the time of purchase. The work images and videos were taken outdoors on a sunny day. The appearance of colors may differ depending on the device used to display the image. We do not accept returns due to design reasons, so please check the images and feel free to contact us if you have any concerns. Since the product is made of glass, please handle it carefully to avoid impacts that may cause scratches or breakage.
