Heidi Klum is another celebrity who loves a little color in her diamonds. Her engagement ring from husband Seal is a fancy yellow cushion cut diamond set in a thin band of small yellow pavé set diamonds. The center stone is estimated to be about 10 carats, and the value of the ring is more than $150,000.

The elongated cut nicely complements Heidi's long, slender fingers. Cushion cuts can be oval, like this one, or more of a rounded square shape, but we think this cut was a perfect choice for Ms. Klum's finger and style.
