What does 1.00ct total weight mean here?

It is the combined weight of all the diamonds in the bracelet, not the size of one stone. Spread across a full line, each diamond is small, so the look is a continuous sparkle rather than a few large stones.

Is 14k white gold good for a bracelet?

14k gold is durable enough for regular wear and holds stones well. White gold is rhodium plated for a bright finish, and that plating fades with wear, so expect re-plating every few years.

How does this compare with a 2ct tennis bracelet?

A 2ct bracelet has roughly double the diamond weight, so stones are larger and the line reads bolder. This 1ct version is lighter and more understated, better for everyday wear and layering.

Will it fit my wrist?

Tennis bracelets typically run about 7 inches, the most common women's length. Check the stated length before buying, since a line bracelet cannot be resized easily without removing links.

What should I check on the clasp?

Look for a box or tongue clasp with a safety latch. A single friction clasp is the most common point of failure on tennis bracelets, so a secondary safety catch matters for daily wear.
