A vibrant, slanted section of blue, a marbled pattern, cuts diagonally across the crystal, adding a dynamic and unique element.  Embedded within the crystal, the color blue evokes a sense of depth and contrast.  On the crystal's surface, two connected hearts in shades of red, with a golden outline, are visible, symbolizing love.  Accompanying this, golden text conveys a message. Furthermore, the 15th-anniversary mark adds a touch of gold. The base on which it is resting appears to be smooth marble. The crystal is likely intended to be a long-lasting memento. The materials and design combine to create a lasting tribute to a special occasion.
