Common Questions
How should a lab-grown diamond tennis necklace fit?
A line necklace is typically worn close to the base of the neck, measuring between 14 and 16 inches that sits above the neckline of your shirt or dress. For an option that falls below the neckline, choose 18 inches for a longer piece. All necks are different, so aim to have the line necklace fall above or below the collarbone.
How to keep a lab-grown diamond tennis necklace from flipping over?
There are several options to help ensure your line necklace stays in place.
Center the clasp at the back and lay the necklace flat on a surface before wearing.
Size the line necklace specific to the wearer.
Soldering the line necklace at key points will aid in stabilizing the settings and add a slight amount of weight.
Avoid wearing similar lengths of necklaces together.
Do all lab-grown diamond tennis necklaces flip?
No, not all line necklaces flip. A heavier line necklace is less likely to flip than a lighter one. It ultimately depends on the specific design, construction of the necklace, and wearer’s collarbone. Graduated line necklaces with larger diamonds in the center allow for more weight in the front of the necklace, which also greatly reduces flipping.
How should I care for my lab-grown diamond tennis necklace?
Clean your necklace gently with warm water, mild soap, and a soft brush. Store it separately to prevent scratches and have the settings professionally inspected regularly.
