Round Cut Lab Grown Diamond Solitaire Ring, 1.00ct Total, Solid Gold

For anyone who wants the classic, this 1 carat lab-grown diamond solitaire engagement ring keeps it simple: one 1.00 ct round diamond, 6.50 mm wide, on a strong 3.16 mm band. The wider shank feels substantial and comfortable for everyday wear, and it balances the center stone so the ring never looks top-heavy. It is a natural choice for a proposal, but it also makes a meaningful self-purchase or milestone gift. Pick yellow gold for a vintage warmth, white gold for icy contrast, or rose gold for a softer glow.
