Description
A bright round lab-grown diamond sits at the center of this yellow gold solitaire necklace, a single point of light that looks polished and calm. The pendant is solid yellow gold with a polished finish, so the warm tone runs all the way through. Four prongs hold the faceted stone with an open back, and it hangs from a cable chain that closes with a spring ring clasp. You can wear it with a white tee and jeans or a black dress for dinner. It suits anyone marking a birthday or an April milestone. Quietly brilliant.

How do I choose between yellow and white gold solitaire necklaces?
Choose by the tone you want beside the stone. Yellow gold gives a warm glow, while white gold looks cooler and brighter against the diamond or cubic zirconia. Both are 14K here, so the choice is about your style and the other jewelry the wearer already owns.
What is the difference between lab-grown diamond and cubic zirconia solitaires?
They are different stones with different makeup. Lab-grown diamond is real diamond created in a lab, while cubic zirconia is a separate man-made stone. Both appear on this page, so check the product title to see which one a necklace uses.
What affects the price of solitaire necklaces?
Stone type and size drive the price most. Lab-grown diamond differs from cubic zirconia, and carat weight or millimeter size matters. Yellow versus white 14K gold and the setting, such as four-prong or a bail, can also play a part. Use the Price filter on this page to set a budget.
Which solitaire necklace styles are most popular?
Round lab-grown diamond solitaires in 14K gold lead the list. Round cubic zirconia styles in 14K yellow gold also rank high, along with four-prong settings and bail styles. For more stones in a necklace, see Diamond Necklaces.
