5.03 ct Marquise Lab Grown Diamond (Colour H, Clarity VS2, IGI Certified)

Five Carats. The Most Dramatic Shape in Fine Jewelry. Certified.

The marquise cut is the most dramatic diamond shape in existence — a long, pointed ellipse with a silhouette that elongates the finger more dramatically than any other cut, creates the largest face-up appearance per carat of any diamond shape, and delivers a brilliance that is entirely its own. At 5.03 carats of H color and VS2 clarity, independently certified by the International Gemological Institute, this marquise is a center stone of extraordinary presence — a stone that will stop conversations, command attention, and look genuinely spectacular on the hand. This is the diamond for the woman who wants to be noticed.

A Transparent Note on Color and Clarity

H Color in a Marquise: Unlike step-cut shapes such as the emerald cut, the marquise's brilliant faceting pattern is highly effective at masking color. H color in a marquise appears white and brilliant to the naked eye in virtually all settings and lighting conditions — an excellent value choice that delivers the look of a colorless diamond at a more accessible price point. In yellow gold, the warmth is completely invisible. In white gold or platinum, H color in a marquise remains an excellent choice.

VS2 Clarity in a Marquise: VS2 inclusions are not visible to the naked eye in typical viewing conditions. In a marquise, the brilliant faceting pattern also helps mask inclusions more effectively than step-cut shapes — making VS2 a strong clarity choice for this shape. However, marquise diamonds can occasionally exhibit a "bowtie" effect — a dark shadow across the center of the stone caused by light leakage — and the severity of this varies by stone. We recommend contacting us to discuss this stone's specific bowtie characteristics and reviewing the IGI certificate before purchase.

The Marquise Cut: The Most Elongating Diamond Shape

The marquise cut has a history as dramatic as its silhouette — legend holds that it was commissioned by King Louis XV of France, who wanted a diamond cut to mimic the shape of the lips of his mistress, the Marquise de Pompadour. Whether or not the story is true, the shape has endured for centuries as one of the most distinctive and flattering in fine jewelry. Its elongated, pointed outline creates the illusion of a longer, more slender finger more effectively than any other diamond shape, and its large face-up surface area means a 5-carat marquise appears substantially larger than a 5-carat round brilliant of the same weight. It is the diamond shape that delivers the most visual impact per carat — and at 5.03 carats, the impact is extraordinary.

IGI Certified: Complete Confidence

This diamond is certified by the International Gemological Institute (IGI), providing independent, third-party verification of every quality characteristic. The IGI certificate travels with the stone and provides permanent documentation of its specifications. We encourage all buyers to review the certificate carefully and contact us with any questions before purchase.

Setting Recommendations

A 5.03 carat marquise is most beautifully showcased in settings that honor its dramatic elongated silhouette — a simple two-prong or V-tip solitaire that protects the delicate points while allowing maximum light entry, or a three-stone setting with tapered baguette or trillion side stones that frame the marquise without competing with it. Yellow gold is a particularly beautiful pairing for H color, and the warm metal tone enhances the marquise's vintage-inspired character. Contact us to discuss custom setting options.

• A custom engagement ring center stone with maximum visual impact and finger-elongating elegance
