Selling Valentine's memento in stained glass

After new year celebration, the young and not anymore young get excited with valentines celebrations. They're thinking of the best keepsake their loves would heartily give to their sweet loves. Others prefer to sell symbolic roses, rings but for the young generations they like something unique and as far as my observation is concerned, they prefer to give their loves stained glass with roses inside. They can keep them for years. Will this be a good business one time during valentines day?
