Are the diamonds mined or lab-grown?

They are lab-grown diamonds, 1 carat in total. Lab-grown stones have the same optical and physical properties as mined diamonds.

What do VVS1, D and Excellent mean?

VVS1 is very high clarity, with inclusions hard to see even under magnification. D is the top colorless grade. Excellent is the best cut grade, which drives sparkle.

How big are they on the ear?

Each earring is about 0.3 in in diameter. That is a small stud that sits close to the lobe rather than a large statement piece.

How do they compare with plain diamond studs?

The stones and grading match what good solitaire studs offer, but the floral cluster shape is more decorative. Plain studs are simpler and snag less.

Are lab-grown diamonds a good choice here?

They give the same look and grading as mined stones. The trade-off is resale value, which is much lower than for mined diamonds.

What should I check before buying?

Confirm the metal and the earring backing, since neither is stated. Also check the return window, because earrings are often excluded from returns for hygiene reasons.
