Is the gold solid or plated?

It is solid 14k yellow gold, so the color runs through the metal rather than sitting in a plating that wears off. That makes it a better long-term buy than gold-plated or gold-filled rings.

How big are the diamonds?

The three white diamonds total 0.58 carat, so roughly 0.19 carat each on average. That is a modest size per stone, and the design leans on the three-band shape rather than on one large center stone.

Will it sit flush with a plain wedding band?

Probably not. The angled topping rises to 13.6mm, so a straight band will likely leave a gap. Look for a curved or contoured band if you want a flush stack.

Is it comfortable for daily wear?

The tallest point is 13.6mm, which is high for a ring and can catch on clothing. It is better suited to occasional or dress wear than to all-day wear with gloves or knitwear.

What should I check before buying?

Ask for the diamond clarity and cut grades, since only color (white) and carat weight are given. Also confirm the ring size options and whether resizing is offered, as the ring is imported.
