Choosing round cut lab diamond engagement rings

Assess the round cut diamond

For a round brilliant diamond, read the cut information supplied by the selected report along with polish and symmetry. Compare the actual stone’s appearance and diameter. Colour and clarity interact with viewing conditions and setting, so use photographs or video alongside the grades.

Look at the complete mounting

Four claws and six claws create different visible frames. Look at whether the band is straight, tapered or diamond set and how the basket sits above it. The same round outline can feel restrained or more detailed depending on those choices.

Compare the selected laboratory information

Read the report issued for your chosen lab grown diamond, including its date, dimensions and relevant comments. Report services and terminology differ. Compare current complete-ring prices with the same stone and mounting specification, and ask for viewing information if appearance is not clear.

A question worth asking

Can a cut grade replace seeing the selected round diamond?

A report gives useful grading information, but the appearance of the actual stone still matters. Compare it in appropriate photographs or video before deciding.
