1 Carat Diamond Engagement Ring

Description

A Complete 1 Carat Diamond Engagement Ring for $1,690

This ready-to-ship solitaire combines a 1.00ct round brilliant lab-grown diamond with a timeless engagement-ring setting in solid 9kt gold.

At one full carat, the centre diamond offers significantly more visual presence than our 0.30ct and 0.50ct options while keeping the complete ring price below $2,000.

Unlike engagement rings where the setting and centre diamond are priced separately, $1,690 is the complete ring price, including the diamond and solid gold setting.

Compare all three sizes in our Ready-to-Ship Engagement Rings collection.

Why Choose a 1 Carat Diamond Engagement Ring?

One carat is one of the most recognised diamond weights for an engagement ring. A well-proportioned 1.00ct round brilliant diamond typically provides a substantial centre-stone appearance while remaining comfortable for everyday wear.

Carat measures diamond weight rather than exact visible diameter, so two one-carat diamonds can appear slightly different in size depending on their proportions and cut. A well-cut round brilliant is designed to balance diameter with light performance, producing the brightness, fire and sparkle associated with this classic diamond shape.

Learn more about how weight affects appearance in our diamond carat guide or compare other designs in our round brilliant diamond rings collection.

Manufacturing these rings efficiently and holding finished stock reduces production time and cost, allowing us to offer this complete 1 carat diamond engagement ring for $1,690.

1 Carat Diamond Engagement Ring FAQs

Is $1,690 the complete engagement ring price?

Yes. $1,690 is the complete ring price, including the 1.00ct lab-grown diamond and solid 9kt gold engagement-ring setting. There is no separate centre-diamond purchase required.

Is a 1 carat diamond the same as 1.00ct?

Yes. 1 carat and 1.00ct refer to the same diamond weight. One carat equals 200 milligrams.

How large does a 1 carat round diamond look?

The exact diameter depends on the individual diamond’s proportions. A well-proportioned 1.00ct round brilliant diamond is commonly around 6.4–6.5mm in diameter, although individual diamonds vary. Carat refers to weight rather than a fixed physical diameter.

Is this a real diamond?

Yes. The centre stone is a genuine lab-grown diamond. Lab-grown diamonds have the same fundamental crystal structure and physical and optical properties as natural diamonds; their principal difference is origin.

Is the diamond IGI certified?

Yes. The centre diamond is independently graded by IGI and supplied with its grading information and identification details.

Can the 1 carat engagement ring be resized?

Yes. The ring can generally be resized. If your required finger size differs from the stocked size, resizing may add additional time before collection or dispatch.
