Weight of Pleaser heels

Hi. Does anyone know if the transparent pleasers are any lighter than the solid coloured ones of the same model? https://www.pleaserusa.com/ProductDetail.asp?div=1_PLEASER&dpt=10_PF&ctg=40_7_HEEL&STYLE_CD=TABOO%2D708&PROD_CD=TAB708%2FC%2FM For example this one. I swear the black ones are filled with rocks. I want a lighter one but I also want the same size platform and heel height. Thanks!
