1.5 Carat Oval Diamonds

A 1.50 ct oval measures roughly 9 by 6.5 mm. Set east-west or north-south it covers noticeably more finger than a round of the same weight, which is why this band has become the default choice for buyers who considered a two carat round and preferred the proportions.

At this size the ratio decision carries more weight, literally. A 1.75 ratio oval at 1.50 ct looks dramatically longer than a 1.30 ratio oval of identical weight, and the slender version tends to photograph better while the fuller version tends to look richer in person. Choose deliberately rather than by price alone.

Colour becomes worth a second look here. Elongated shapes concentrate any warmth at the two ends, so a colour I stone that looks perfectly white as a round can show a faint tint at the tips as an oval. G or H is the comfortable range at this size.
