A Complete 0.50ct Diamond Engagement Ring for $1,290

This ready-to-ship solitaire combines a 0.50ct round brilliant lab-grown diamond with a classic engagement-ring setting in solid 9kt gold.

At half a carat, the centre diamond provides noticeably more presence than a 0.30ct diamond while keeping the complete ring price below $1,500.

Unlike engagement rings where the setting and centre diamond are priced separately, $1,290 is the complete ring price.

Why Choose a 0.50ct Diamond Engagement Ring?

A half-carat diamond is a popular choice for buyers who want a noticeable centre diamond without moving to the price of a one-carat ring.

Carat measures diamond weight rather than its exact visible diameter, so cut and proportions are also important when comparing diamonds. A well-cut round brilliant is designed to return light efficiently and create strong brightness, fire and scintillation.

Why Is This Diamond Engagement Ring Such Good Value?

Polished Diamonds created the Ready-to-Ship collection for customers looking for a quality diamond engagement ring at a competitive and transparent price.

Rather than individually redesigning every ring after an order is placed, we concentrate on one proven solitaire engagement-ring design, selected diamond sizes and solid 9kt gold.

Producing these rings efficiently and holding completed stock reduces manufacturing time and cost.

You still receive a genuine lab-grown diamond, solid gold setting, independent IGI grading and ongoing support from Polished Diamonds. If you would like to understand more about diamond origin and value, read our guide to lab-grown diamonds.
