1.3 Carat Diamond Ring

Why Is a 1.3ct Diamond Ring Ideal for a Statement Piece?

A 1.3 ct diamond ring provides a significant presence on the finger and is suitable for everyday elegance. A carefully chosen combination of Excellent or Ideal cut, SI2 clarity, and colour (J for platinum or white gold settings, or K for yellow gold) guarantees optimal brilliance and sparkle for round diamonds in this weight range. Our 1.3 carat engagement rings create a big impression without reaching the higher price tier of heavier stones. Shop with Flawless for the balance of size, quality, and precision cut

 

How Noticeable Is a 1.3ct Diamond Compared to Smaller Sizes?

 

Compared to smaller diamonds, including those in the 1.0–1.2 carat range, a 1.3-carat diamond is more noticeable. It provides more finger coverage and a dominating appearance because of its round 1.3ct diamond, which usually has a diameter of 6.8–6.9 mm. For those looking for a diamond that stands out as the focal point of an engagement ring, our 1.3 carat solitaire diamond ring is a perfect choice.

1.3 Carat Diamond Ring- FAQ's

How large does a 1.3ct diamond appear when set in a ring?

The face-up area is approximately 40.6 mm², which is ideal for this weight. This means the diamond “looks its weight” and provides noticeable presence without being oversized.

What cut grade is recommended for a 1.3 carat round diamond?

To maximise brilliance and fire, always choose a cut grade of Excellent (GIA) or Ideal (AGS). A high-quality cut ensures the diamond appears bright and lively, even if clarity or colour is modest.

How does cut influence the appearance of a 1.3 carat diamond?

Cut affects brilliance, sparkle, and overall visual size. Well-cut diamonds in this weight range can appear larger and brighter than heavier stones with average cuts.

What length-to-width ratio is ideal for a 1.3ct round diamond?

A ratio between 1.00 and 1.02 ensures a perfectly round look that maximises the stone’s aesthetic appeal and symmetry.
