1 Carat Transitional Cut Diamond Engagement Ring Platinum.  This interesting Art Deco engagement ring features a dazzling 1.01 carat transitional cut diamond and is set in platinum. The shoulders contain .24 carats of accent diamonds of which are round cuts as well as baguettes. The center stone is set with fishtail prongs inside a square shaped element that separates it from the rest of the accent stones. The shoulders split and run toward the center with bezel set baguettes that are separated from the center by milgrain detail and more round cut diamonds. The ring contains 1.33 carats of diamonds but their placement creates a much larger look that that would imply, in a very interesting design nonetheless.
