Are lab-grown diamonds real diamonds?

Yes. They are chemically and optically identical to mined diamonds, just grown in a lab. They rank 10 on the Mohs hardness scale, same as mined stones.

Why choose an emerald cut over a round stud?

Emerald cuts have large, open facets that give a hall-of-mirrors look instead of sparkle. They are more forgiving of a busy outfit but less forgiving of a weak stone, so cut quality is the deciding factor.

What gold options are there?

The earrings come in 14k or 18k gold in white, yellow or rose. Higher karat gold is softer and warmer in tone; 14k white gold is the most durable for daily wear.

How do I choose the carat weight?

Total carat weight is split across both earrings, so a 4tcw pair is about 2 carats per ear. Larger emerald cuts cover more of the ear and look more formal; smaller ones sit closer to the lobe.

Will emerald cut studs show flaws?

More than round brilliants. The wide, flat table leaves inclusions and color visible, so ask for the stone grades and a video before committing.

What backs do they have?

The listing does not state the backing type. Ask the seller whether they use push backs, screw backs or friction posts, since that affects security for daily wear.
