Nature’s most coveted color in diamond’s hardest form — a 4 carat fancy vivid green radiant cut lab grown diamond flanked by two trapezoid side stones totaling 5.80 carats across all three diamonds. The radiant cut’s 70 brilliant facets amplify green across the entire 10.20x8.20mm surface like a sunlit forest captured in geometric perfection — creating the richest, most saturated green presentation any rectangular diamond shape can deliver. The two 0.90 carat trapezoid diamonds taper seamlessly against each side, their bright white sparkle creating a striking contrast that makes the green center appear even more vivid — like morning sunlight streaming through a canopy. Unlike traditional emerald gemstones (7.5–8 Mohs, prone to chipping, cracking, and clouding over decades), this green lab grown diamond rates a perfect 10 on the Mohs hardness scale — it will look as intensely green in 50 years as it does today. Set in yellow gold for a natural, earthy harmony of vivid green and warm gold, or in white gold for a cool-toned botanical drama that commands attention from across any room.

What You Get That They Don’t Offer

• 4 carat vivid green radiant — the most nature-inspired three-stone design available. No competitor offers a 4ct green radiant center with trapezoid sides. The radiant’s 70 facets amplify green to its most vivid saturation, creating a gemstone that rivals the finest emeralds without any of their fragility
• Green lab diamond = 10 Mohs hardness vs. emerald’s 7.5–8 — if you love green but need a stone that will never chip, crack, or cloud over time, a green lab grown diamond is the superior choice. This ring will look as vivid in 50 years as it does today. Emeralds cannot make that promise
• 5.80 total carats — the green radiant center plus two 0.90 carat trapezoid sides deliver a total weight that competitors cannot match in their green diamond collections
• Trapezoid sides frame the green center with geometric precision — the tapered white trapezoids create seamless visual flow while their bright sparkle contrasts dramatically with the vivid green, making it appear even more saturated
• Green radiant in yellow gold = nature’s palette — vivid green center, sparkling white trapezoid sides, and warm yellow gold harmonize like sunlight on a forest floor. The most earthy, organic-feeling engagement ring available
• Lab-grown and conflict-free — the most ethical way to wear a rare 4 carat green diamond. Zero mining impact, identical chemical composition to mined diamonds
• 10K gold and Platinum Pure options — from the most accessible entry to the most premium setting for a 5.80ct green diamond ring. No competitor offers this range
• Handcrafted to order — your exact ring size, metal karat, and gold color
• Free worldwide shipping and insurance included — competitors charge extra for both
