Is a 7-carat lab-grown diamond tennis bracelet worth it?

You get a lot of diamond look for the money because lab-grown stones cost less than mined ones of the same size and grade. The trade-off is resale value: lab-grown diamonds hold little of their cost secondhand. Buy it for wear, not investment.

How does this compare with a mined-diamond tennis bracelet?

Visually it is close: F color and VS2 clarity are strong grades, and the 7-carat total gives real presence. A mined bracelet of the same weight and grade would cost several times more. The difference shows up in resale and in how some buyers view lab-grown stones.

Will 7 inches fit my wrist?

Seven inches is a common women's bracelet length and fits many wrists with a little drape. Measure your wrist and add about half an inch for comfort. If your wrist is over roughly 6.5 inches, the fit may be snug.

What is a box clasp and is it secure?

A box clasp slides into a rectangular housing and usually includes a figure-eight safety catch. It sits flush with the bracelet for a clean look. Check the safety catch is closed, since prong-set bracelets can catch on sleeves.

Are the diamonds real?

They are real diamonds grown in a lab rather than mined. They have the same physical and optical properties as mined diamonds. They are graded F color and VS2 clarity and set in 14K white gold.

How should I care for a white gold diamond bracelet?

Clean it with mild soap, warm water and a soft brush, and check the prongs periodically. White gold is rhodium-plated, so re-plating every year or two keeps it bright. Store it separately so the diamonds do not scratch other jewelry.

Our take on the KAY Lab-Grown Diamonds Tennis Bracelet 7 ct tw 10K

A 7-inch tennis bracelet from KAY's lab-grown diamond line, set in 14K white gold with round lab-grown diamonds at each link and a total weight of 7 carats. The stones are graded F color and VS2 clarity in prong settings, which is a high spec for a line bracelet at this carat weight. Lab-grown diamonds cost far less than mined stones of the same size and grade, so the value here is carat weight and color/clarity rather than rarity. It suits someone who wants a bright, formal line bracelet for events and everyday wear and does not mind a lab-grown origin.
