Our take on the Kay Bliss Princess-Cut Lab-Grown Diamond Engagement Ring 18K White Gold

The Kay Bliss is a solitaire engagement ring in 18K white gold with a princess-cut lab-grown diamond. The square cut gives a sharper, more modern look than a round brilliant, and the four-prong setting keeps the stone the focus. Lab-grown diamonds are chemically identical to mined ones and cost less, so more of the budget goes into the gold and setting. It suits shoppers who want a clean, contemporary solitaire and are comfortable with a lab-grown stone.

Questions and answers

Is a lab-grown diamond a real diamond?
Yes. It is chemically and optically identical to a mined diamond, just grown in a lab. Only a trained gemologist with equipment can tell them apart.
How does the princess cut compare with a round brilliant?
The princess cut is square with pointed corners and gives a sharper, more geometric sparkle. A round brilliant throws more fire and hides flaws better, and its corners cannot chip.
Will the white gold stay white?
18K white gold is rhodium-plated to look bright white. The plating wears over years, so expect re-plating every year or two with daily wear.
Can it be worn with a wedding band?
Yes. The plain solitaire band sits close to most straight wedding bands. Curved bands fit better if you want the rings to sit flush.
Does it come with a diamond certificate?
Lab-grown stones of this size usually ship with a grading report from a lab such as IGI. Confirm the report is included before you buy.
Is a princess-cut stone fragile?
The pointed corners are the weak spot. A four-prong setting that covers the corners protects them, but avoid hard knocks and have the prongs checked yearly.
Where is the Kay Bliss Princess-Cut Lab-Grown Diamond Engagement Ring 18K White Gold cheapest?
At Kay Jewelers, for $3,769.99, as of our latest check.
