A 1ct marquise diamond ring features a marquise cut diamond weighing approximately 1 carat, typically measuring around 10.5mm x 5mm[3]. The marquise is an elongated, elliptical shape with pointed ends, also known as the navette shape, designed to maximize both visual size and brilliance[2][6]. This cut dates back to 18th-century France and was designed to resemble the lips of the Marquise de Pompadour[6].

The marquise cut diamond is notable for creating the illusion of a larger carat size compared to other cuts, making the wearer’s finger appear longer and more slender[2][6]. Prices for a 1ct marquise diamond can range from around $4,300 to $4,920, depending on quality and source[1]. Retail prices for 1ct marquise solitaire engagement rings can reach approximately $6,500, especially for GIA certified stones set in fine metal[7].

Key features of the marquise cut include:

  • Shape: Elongated with pointed ends, maximizing surface area and face-up size per carat[8].
  • Facet Count: Typically 56 to 58 facets for exceptional sparkle[2][6].
  • Best Settings: Prong settings are recommended to protect pointed ends; popular designs include solitaire, halo, and vintage-inspired rings[2][5].
  • Style Compatibility: Versatile for both classic and modern ring settings, and available in white, yellow, or rose gold and platinum[2][3].
  • Care Needs: Extra care should be taken to shield the pointed tips from chipping; regular prong checks are advised[2].

Marquise diamonds are also appreciated for their efficient use of rough diamond material and are considered a smart choice for those seeking a large-looking, distinctive, and elegant engagement ring[2][6].
