At the base and the top of the crystal award, there's a section made of beautifully patterned marble. The marble provides a solid and contrasting foundation for the clear crystal section. Its hue is a rich, forest-like green color, with variations in tone and veining adding depth and character to the design. The transition between the crystal and the marble is seamless, further enhancing the award's luxurious aesthetic. The award features a circular emblem, adorned with a 15, and other text, all in a vibrant golden hue. The font used for the inscriptions is a classic, readable style.  

 

This design, combining clear crystal with green marble, together creates a piece that is visually engaging and truly memorable. The award is a treasure, celebrating the meaningful occasion.
