1.6 ct Radiant Lab Grown Diamond (Colour F, Clarity VS1, IGI Certified)

Premium Quality in a Radiant Cut. Certified.

F color and VS1 clarity represent a premium quality combination that experienced diamond buyers consistently seek out — near-colorless at the top of the scale, eye-clean with exceptional transparency, and independently certified by the International Gemological Institute. At 1.6 carats in a radiant cut, this stone delivers the bold, rectangular presence and brilliant-cut fire of the radiant shape in a size that is substantial, wearable, and genuinely beautiful. This is the center stone for a ring that will be worn with complete confidence every single day.

The Specifications

• 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 1.6 carats, this is the stone.

The Radiant Cut: Bold, Brilliant, and Versatile

The radiant cut brings together the best qualities of two iconic diamond shapes — the bold, substantial rectangular outline of the emerald cut and the explosive fire and scintillation of the round brilliant. Its cropped corners eliminate the vulnerability of the princess cut's sharp points, while its brilliant faceting delivers a display of light that step-cut shapes simply cannot match. At 1.6 carats, the radiant cut's rectangular silhouette creates a presence on the finger that appears larger than a round brilliant of the same weight, making it one of the most efficient shapes for visual impact per carat.

The Annie Connection

The radiant cut is the same diamond shape featured in The Annie — our 7.51 carat named original engagement ring with hidden halo and accented band. If you love the character of The Annie and are considering a custom ring at a more accessible price point, this 1.6 carat F/VS1 radiant offers the same bold, brilliant shape with premium quality grades. Contact us to discuss custom setting options inspired by The Annie 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 F color, VS1 clarity, radiant cut, and 1.6 carat weight.

Setting Recommendations

A 1.6 carat radiant cut works beautifully in a wide range of settings — a four-prong solitaire that showcases the rectangular silhouette cleanly, a halo that adds surrounding brilliance and apparent size, or a three-stone setting with tapered baguette or half-moon side stones. 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.
