Here is a description of the paperweight from this angle:
Faceted Starburst Geometry: The square paperweight features a molded or cut inner rim with distinctive triangular, prism-like points pointing inward from each of the four sides, creating a dynamic, geometric starburst pattern.
Vibrant Prism Colors: The corners and edges are treated with a rich rainbow gradient. In this lighting, you can clearly see distinct sections of deep blue, amber gold, emerald green, and ruby red.
Light Refraction: Because of the sharp, faceted cuts along the inner walls, the colored edges project outward, casting sharp, beautiful rainbow-colored flares onto the dark surface to the left and right of the piece.
Surface Presentation: It is resting on a dark, matte, or finely speckled black surface, which heavily contrasts with the clear glass and makes the refracted color spectrum pop intensely.
