One and a Half Carats. F Color. VS1. The Elongated Cushion. Premium Quality. Certified.

F color is the third-highest grade on the GIA scale — essentially colorless, appearing absolutely white and brilliant with no detectable warmth in any setting or lighting condition. VS1 clarity is the stronger of the two VS grades, delivering inclusions that are invisible to the naked eye and extremely difficult to find even under magnification. At 1.61 carats in an elongated cushion cut, independently certified by the International Gemological Institute, this stone delivers the cushion's signature soft, pillowy brilliance in a premium near-colorless, completely eye-clean quality combination — at a price that makes this level of quality genuinely accessible. This is the center stone for a ring of genuine beauty and everyday confidence.

The Specifications

• Certification: IGI Certified — International Gemological Institute; independent third-party verification of F color, VS1 clarity, elongated cushion cut, and 1.61 carat weight
• Origin: Lab-Grown — Physically, chemically, and optically identical to a mined diamond; conflict-free and ethically sourced

Why F/VS1 Is a Premium Quality Choice

F color sits at the very top of the near-colorless range — just two grades below the theoretically perfect D color — and is essentially indistinguishable from D or E to the naked eye in virtually all conditions. VS1 clarity is the stronger of the two VS grades, delivering inclusions that are invisible to the naked eye and extremely difficult to find even under magnification. Together, F/VS1 delivers a stone that looks and performs at the highest level — completely colorless in appearance, completely eye-clean in clarity, and certified to confirm it. For a buyer who wants premium quality at 1.61 carats, this is the stone.

The Elongated Cushion: Romantic, Flattering, Wearable

The elongated cushion cut's longer length-to-width ratio creates a more finger-flattering appearance and a larger face-up surface area than a square cushion of the same carat weight, while its rounded corners and brilliant faceting deliver the warm, pillowy light performance that makes the cushion cut one of the most beloved shapes in engagement ring history. At 1.61 carats, the elongated cushion is the ideal size for a ring that is beautiful enough to be noticed and comfortable enough to wear every single day — the sweet spot between presence and practicality.

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 looking for an accessible entry point into the elongated cushion, this 1.61 carat F/VS1 stone offers the same romantic silhouette with premium quality grades at a price that makes a custom Diana-inspired ring genuinely within reach.

IGI Certified: Complete Confidence

This diamond is certified by the International Gemological Institute (IGI), providing independent, third-party verification of the F color, VS1 clarity, elongated cushion cut, and 1.61 carat weight. The certificate travels with the stone and provides permanent documentation of its specifications.

Setting Recommendations

A 1.61 carat F/VS1 elongated cushion works beautifully in virtually any setting style — a simple four-prong solitaire that showcases the cushion's soft silhouette, a hidden halo that adds brilliance without obscuring the outline, or a pavé band that adds continuous sparkle along the shank. F color pairs beautifully with all metal tones — white gold and platinum for a cool, luminous look; yellow gold for a warm, vintage-inspired character. Contact us to discuss custom setting options.
