The mirror appears to have v-grooving to create the diamond pattern, there are less expensive ways to make the look of v-grooving using a tape or you can have the design sandblasted/etched into the mirror, but it won't have the beveled edge look of v-grooving. The frame can cost more than the mirror depending on the frame you choose, so if you choose a less expensive frame that helps reduce the cost. A commercial glass company in your area should have access to ordering v-grooved glass or getting the tape. If you still need help we may be able to get you to a company that can help you.
