Speaking of heart-shaped sapphires, of course the first thing that comes to mind is the "Heart of the Ocean" from the movie "Titanic".
The color combination of rose gold and royal blue sapphire has a great visual effect, creating a classic and retro style, making the heart-shaped sapphire more elegant and beautiful.
The heart-shaped sapphire matches the style of the surrounding stones very well, giving it a unique girlish look.
