Hi RaggedMonk, yes- these are for sale now. My wife Melanie and I are custom jewelers and all of the jewelry that you see on this thread was drawn by our CAD artist. We can modify it in any way that you wish, and can produce it in most common jewelry materials like sterling silver, white or yellow gold (14K, 18K, 22K), palladium 950, or Platinum 900 or 950.
We don't have a price list because we don't know the weight of a finished piece of jewelry to fit you. If you want a copy of our policies and procedures just ask- this includes information on the fees incurred for each step in the process. Most of the cost of a ring would be in the weight of the metal- except for silver because that is the most economical material. In that case, making the model of your ring to cast (including the CAD design) is the most costly component. Some people shy away from silver because it tarnishes, but we simply plate it with rhodium- just like white gold and platinum are plated with rhodium- and that problem is solved.
Let me know if you have any questions!
