4.04 ct Elongated Cushion Lab Grown Diamond (Colour E, Clarity VS2, IGI Certified)

Four Carats. Near-Flawless Color. The Elongated Cushion.

E color is the second-highest color grade on the GIA scale — essentially colorless, appearing absolutely white and brilliant with no detectable warmth under any conditions. At 4.04 carats of E color and VS2 clarity, independently certified by the International Gemological Institute, this elongated cushion is a stone of exceptional quality and extraordinary presence. The elongated cushion's soft, pillow-like silhouette and longer profile flatter the finger beautifully while delivering the pillowy, romantic brilliance that has made the cushion cut one of the most beloved diamond shapes in fine jewelry. This is a center stone for a ring of genuine distinction.

Why E Color Is Exceptional

E color sits at the very top of the near-colorless range — just one grade below the theoretically perfect D color — and is essentially indistinguishable from D to the naked eye in virtually all conditions. In a cushion cut, E color delivers a stone that appears absolutely white and brilliant from every angle, in every light, in every metal. There is no warmth to consider, no setting color to compensate for, no trade-off to make. E color is the choice of the buyer who wants the best — and at this price for a 4-carat elongated cushion, it represents exceptional value for the quality delivered.

A Transparent Note on VS2 Clarity

VS2 clarity means inclusions are not visible to the naked eye in typical viewing conditions. In a cushion cut, the brilliant faceting pattern helps mask inclusions effectively — more so than step-cut shapes like the emerald or Asscher — making VS2 a strong clarity choice for this shape. We recommend reviewing this stone's IGI certificate and contacting us to discuss the specific nature and position of any inclusions before purchase. We are fully transparent about this stone's characteristics and will answer every question honestly.

The Elongated Cushion: Romantic, Flattering, Unmistakable

The elongated cushion cut is one of the most sought-after diamond shapes in contemporary fine jewelry — a soft, pillow-like silhouette with rounded corners and a longer profile that flatters the finger beautifully while delivering exceptional, pillowy brilliance. Unlike the standard cushion, the elongated ratio creates a more finger-flattering appearance and a larger face-up surface area, making the stone appear even more substantial than its 4.04 carat weight suggests. It is the cut that has captivated collectors and brides alike for its combination of romantic softness and genuine presence.

The Diana Connection

The elongated cushion is the same diamond shape featured in The Diana — our 5.51 carat named original engagement ring. If you love the shape of The Diana and are considering a custom ring around a stone of your own choosing, this 4.04 carat E/VS2 elongated cushion is an exceptional starting point. Contact us to discuss custom setting options inspired by The Diana or any other design.

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 E color, VS2 clarity, elongated cushion cut, and 4.04 carat weight.

Setting Recommendations

A 4.04 carat elongated cushion is most beautifully showcased in settings that honor its soft, romantic silhouette — a simple four-prong solitaire, a hidden halo that adds brilliance without obscuring the cushion's outline, or a three-stone setting with half-moon or tapered baguette side stones. All metal tones work beautifully with E color — white gold and platinum for a cool, luminous look; yellow gold for a warm, vintage-inspired character. Contact us to discuss custom setting options.

Perfect For

• A custom engagement ring center stone with exceptional color quality and romantic cushion brilliance
• A buyer who wants E color — near-flawless — at an accessible price for the carat weight
