Marquise-shaped diamonds, also called Navette diamonds, have pointed ends that resemble a boat sailing on water. Marquise-shaped diamonds need to have a certain thickness to let light travel and reflect inside, which gives them their stunning brilliance and fire. This unique shape blends classic and modern styles, making it perfect for special anniversaries or engagements. Marquise diamonds symbolize walking hand in hand through life's ups and downs, no matter what challenges you face together.
