Square Radiant For Sale on 1stDibs

Find the exact square radiant you’re shopping for in the variety available on 1stDibs.

Find an antique version now, or shop for 1 vintage or 18 modern creation for a more contemporary example of these cherished accessories. Finding the perfect square radiant may mean sifting through those created during different time periods — you can find an early version that dates to the 20th Century and a newer variation that were made as recently as the 21st Century. As it relates to this specific piece, our collection includes designs that are universally popular, but 1 Carat and 1.5 Carat carat weights, specifically, are sought with frequency. Finding an appealing square radiant — no matter the origin — is easy, but Fine Jewels UK, Gregory Mikaelian & Sons, Inc. and Hearts On Fire each produced a popular version that is worth a look. A square radiant can be a stylish choice for most occasions, but Diamond rings, from our inventory of 16, can add a particularly distinctive touch to your look, day or night. Today, if you’re looking for a radiant cut version of this piece and are unable to find the perfect match, our selection also includes alternatives. There aren’t many items for men if you’re seeking a square radiant, as most of the options available are for women and unisex.
