Chase away the moody blues with our curated collection of unique, responsibly sourced blue gemstones. These gemstones come in all hues of blue: from light, spring sky azure to a deep, royal indigo. Loved and coveted for decades, blue gemstones bring a regal, glamorous energy to their wearers. Sapphires, aquamarines, zircon, moissanite, topaz, and tourmaline can all exhibit eye-catching shades of blue and each of these stones can be cut into a unique shape, from more traditional cuts like round and pear to show stopping and unique shapes like trillion and trapezoid.


Once you select your beautiful blue gemstone, it is time to set it in a unique Brilliant Earth design. Choose from a wide range of styles, from sophisticated solitaires to luxe, diamond-accented bands.

Blue gemstones are offered in a variety of dimensions ranging from under 6mm to 10mm and larger, with common groups including under 6mm, 6–6.9mm, 7–7.9mm, 8–9.9mm, and 10mm+. Selecting the dimension that fits your setting and design preference helps narrow choices.
