I'm glad to help. I have found that the cost of structures increases with subsequent  purchases. I didn't keep track of the original costs, or the cost for the second and third of each structure. For most structures the cost will be for the 4th puchase of each, except where noted. I'm not aware of any discounts to be had. Here are the costs in diamonds for 4th purchases: Fruit Tree 360; Masher 560; Garden Patch 570; Bakery 580; Bog 590; Jeweler (for the 2nd purchase) 130; Diamond Extractor 3,200; Workshop 600; Juicer 610; Ice Machine (for the 2nd purchase) 150; Cooking Pot 660; Apothecary (for the 5th purchase) 1,050; Weavers 730; Candy Factory 750; Tailor 790; Toy Factory 860. Note that I have only one Jeweler and one Ice Machine so far. I do remember that the cost of my third Diamond Extractor was 1,600 and I "think" the second was 800, so it appears the cost doubles with each subsequent purchase, although I can't confirm this for all structures.
