Argh, after finally finding a diamond that I like (see this thread) that was from an Australian store, it seems that setting it locally is going to blow my budget as I was quoted $5000 for a design based on the harmony setting from Whiteflash which I modified to a 6 prong and increased the shank thickness near the head. My mockup and the original harmony are below. Sorry for the poor photoshop skills.

Original Harmony

This means that I may have to choose another diamond, getting the setting from the same place. Seeing this is kind of similar to the standard harmony, which costs $2150 in platinum, what kind of price do you think I could expect from Whiteflash? Does anyone have any experience with custom rings from Whiteflash (are they good to work with, especially if you are from another country)?
