Blue Lab Grown Diamonds

82 stones in our inventory - hand-selected and personally evaluated

Blue is one of the rarest colors a diamond can have. In lab-grown diamonds, blue color is typically associated with boron incorporated during growth - the same element behind the famous natural blues. Every blue stone we carry is IGI-certified, with its color and intensity graded, ranging from Fancy Intense to deep, saturated Fancy Vivid. Blue rewards careful selection more than almost any other color: tone and saturation shift noticeably from stone to stone, and two diamonds with the same grade on paper can look quite different in person. A certificate tells you the category; it doesn't tell you how the blue actually reads in different light, or how even the color is across the stone. That is exactly the kind of thing we check by eye. Eldad inspects each blue stone personally and will show you how it behaves in daylight and indoors before you decide. If you're after a blue centerpiece or a distinctive engagement ring, let's talk it through.
