Is a lab grown diamond a real diamond?

Yes. It is chemically and optically the same as a mined diamond, just grown in a lab. It will test as a diamond on a jeweler's tester.

Will the princess cut chip?

Princess cuts have four sharp corners, which are the most vulnerable points. A pendant setting protects the back, but take it off for gym sessions and heavy cleaning.

Does it come with a certificate?

Helzberg lab grown pieces typically ship with grading paperwork from a lab such as IGI. Confirm the certificate is in the box when it arrives.

Can the chain be swapped or lengthened?

The pendant has a standard bail, so it fits most chains. An 18-inch rope is fixed length; a jeweler can add an extender or you can move it to a longer chain.

Is it worth it versus a mined diamond pendant?

For the same half-carat look, a lab grown stone costs far less. If resale value matters to you, mined holds value better; for wear, lab grown is the better buy.

Is 1/2 ct. tw. one stone or several?

It is one princess-cut stone of about half a carat total weight. There are no side stones.

Our take on the Helzberg Lab Grown Diamonds 1/2 ct. tw. Lab Grown Diamond Princess-Cut Solitaire Pendant Necklace 14K Yellow Gold 18"

A 14K yellow gold solitaire pendant on an 18-inch rope chain, set with a half-carat princess-cut lab grown diamond. The square brilliant cut gives it a sharper, more geometric look than a round solitaire, and lab grown means the same size stone costs far less than a mined one. Helzberg sells it as a standalone piece, so the price is the same wherever the chain is bought.
