A 3.5 carat diamond is often considered the ideal middle ground for shoppers looking to maximize visual size without stepping into the significantly higher price range of a 4 carat diamond. With approximately 50% more weight than a 3 carat diamond, a well-cut 3.5 carat stone delivers a noticeably larger appearance and greater finger coverage, making it a popular choice for engagement rings and diamond jewelry.
One of the biggest advantages of choosing a 3.5 carat round-cut lab-grown diamond is value. While a 4-carat lab-grown diamond may only appear modestly larger to the eye, its price can increase substantially due to the rarity of larger diamonds. A 3.5 carat round diamond allows shoppers to enjoy an impressive size upgrade while often saving hundreds of dollars compared to a similar quality 4 carat stone.
All our diamonds are certified by either the IGI, AGS or GIA – the most respected independent grading labs in the world.
