Amethysts as Table Decorations

I have always wanted to make a tablescape full of amethyst clusters....imagine it's 15 feet long and narrow with purple violets and hyacinths and muscari and fresh green moss tucked in and classic black cast iron urns filled with tall white dogwood branches.....and maybe rows of glasses of some fun sparkling lavender colored cocktail.......but for now I shall be content with our little display underneath the orchid table. :)
