The best of the best. A 1 carat diamond is a perfect choice for the center stone of an engagement ring or to adorn on a diamond pendant. With its exceptional presence, a 1 carat flawless diamond offers remarkable brilliance and is sure to be an eye-catching piece. While diamond dimensions vary based on shape and cut, a well-cut 1 carat diamond delivers extraordinary sparkle and visual impact, making it a favorite among those looking for a truly unforgettable ring.
Flawless is the most desired, highest clarity grade a diamond can get. For a diamond to be identified as Flawless, or FL, it must look clear at 10x magnification. This means there are no visible signs of inclusions or blemishes under a 10x magnification. To the naked eye, to say flawless diamonds capture a breathtaking sparkle would be an understatement.
All our diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world. You'll find a curated selection of flawless diamonds in a variety of shapes, including round, oval, cushion, emerald, pear and more. Compare diamonds side by side, view detailed grading information and find the perfect stone to create a breathtaking engagement ring that reflects your style and budget.
