Yes, this was done by a Redditor. You guessed right.
When DisturbedRobot met his girlfriend at a Battlestar Galactica party, he knew he had to put a ring on it. So he came up with the idea of making a ring that looks like a Cylon and aimed for the stars. He used the gold / diamonds from his grandmother’s ring, had his sketches modeled in Maya and then reforged by jewelry crafter Craig Elliott into the scifi based on his specifications.
