Gift her tomorrow with a gem born today—this 4.06 ct cushion-brilliant CVD lab-grown diamond, IGI-certified G VS1 with EX/EX polish & symmetry, is destined to become the heartbeat of an unforgettable proposal. Set into a platinum solitaire or a halo engagement ring, its perfect facets mirror the promise of forever, catching candlelight in every restaurant from Paris to Palm Beach. Once exchanged as wedding bands, the identical stone can be flanked by pavé diamonds to create a seamless “past, present, future” trilogy, symbolizing enduring love that outshines time itself. Beyond romance, the rarity of a 4-carat, eye-clean cushion commands the attention of collectors seeking portfolio-grade gems. Each stone arrives with laser-inscribed IGI tracking, ensuring authenticity and future liquidity in the fast-growing lab-diamond market. Finally, when birthdays, anniversaries or the December holidays call for a statement gift, present this diamond in a velvet box—an heirloom-in-waiting that whispers luxury without the ethical baggage of mining.
Meet the stone that rewrites the rules of luxury: a 4.06-carat Cushion Brilliant lab-grown diamond, laser-cut to EX/EX symmetry and polish by master lapidaries in state-of-the-art CVD reactors. IGI certifies it G-color—icy white to the naked eye—and VS1-clarity, meaning any inclusions are microscopic and invisible without 10× magnification.
That combination of size, precision, and purity is normally reserved for seven-figure mined gems, yet this ethical masterpiece arrives at a fraction of the cost and carbon footprint. Designed for modern brides, style-forward professionals, and eco-conscious investors across the U.S. and Europe, the stone delivers red-carpet fire and heirloom durability. Set it in a platinum solitaire for a proposal that trends on Instagram, or flank it with tapered baguettes for a bespoke anniversary gift that whispers understated wealth.
With conflict-free provenance and next-generation sparkle, this 4.06 ct Cushion Brilliant is more than a diamond—it’s a manifesto for the values of the new luxury consumer.
