How much is a 4 or 5 carat engagement ring?

With a lab grown centre stone in 14K gold, as of October 2026: from $4,500 CAD at 4 carats (median $5,100 CAD) and from $5,200 CAD at 5 carats (median $5,800 CAD). Our listings go up to 7 carats. A natural stone at this size is a different budget, so we quote both. The full table is in lab grown diamond ring price by carat.

What setting holds a large diamond best?

Something that ties the prongs together. On a big round, four claw prongs need a hidden halo or gallery rail underneath; six prongs become six petals that support each other. Carlos's 6.02 carat radiant and Juan's 5 carat marquise also sit on a euro shank, added to keep them stable and balanced. See 4 vs 6 prongs and low profile engagement rings.

Will a large stone look too big?

Carat is weight, so the shape and ratio decide how big it reads. A hidden halo adds sparkle from the side without changing the top view. Riley and Tyler's 4.52 carat Dutch marquise sits in an engraved half bezel, and Lee's 4 carat radiant has an outer halo. See carat vs ratio.
