A 1.2 carat diamond ring typically features a diamond weighing 1.2 carats, which is a popular and visually impactful size for engagement rings. The average price for a 1.2 carat round diamond ranges from $1,718 to $13,949, with an average around $5,795 depending on factors such as shape, color, clarity, and cut quality[1]. For round cut stones specifically, a 1.2 carat diamond generally measures about 6.91 x 6.91 x 4.17 mm, yielding a face-up area of around 37.5 mm², which looks substantial when set in a standard ring and is considered a visually satisfying size for most buyers[2].
The price varies significantly based on other diamond quality attributes. For example, the most common color grade for engagement rings is H (near colorless), and the most frequently selected clarity grades are VS2 (Very Slightly Included 2) and SI1 (Slightly Included 1)[1]. Stones with higher grades in color and clarity, as well as an excellent cut, will cost more. For example, a GIA certified, 1.2 carat round cut diamond ring may be priced at around $9,500 if it features high color and clarity grades[5], while lower graded stones of the same weight might be significantly less.
Other popular shapes for a 1.2 carat diamond include oval, princess, and cushion, each with different dimensions and face-up appearance. A 1.2 carat oval cut, for instance, typically measures around 8.5 x 6.14 mm and has a slightly larger face-up area due to its elongated shape[4].
In summary, a 1.2 carat diamond ring is highly sought after for offering an excellent balance between size, brilliance, and price. Buyers should pay careful attention to the quality factors—cut, color, clarity, and shape—to ensure the diamond not only looks impressive but also retains its value and desirability over time[1][2][3].
