Start with how often you will wear it. A small lab-grown diamond pendant on a fine chain is the everyday choice; a pavé heart or a tennis necklace is the statement piece. Then check three things: the total carat weight, the metal, and whether the chain is included. Our lab-grown pendants start at $749.99 for a 0.30 ct TW pendant in 14k yellow gold with its chain.
Which style suits how you will wear it?
- Everyday pendant: a small, light piece that goes with everything, from work to weekends.
- Initial or symbol pendant: personal and giftable, with more sparkle from many small pavé-set stones.
- Pavé heart: a larger shape covered in small lab-grown diamonds, worn alone or layered.
- Tennis necklace: a continuous line of lab-grown diamonds all the way around, the most formal option.

What does the carat number mean on a necklace?
On a piece with many stones, the figure is the total weight of all of them, which is why it is labeled TW. A carat measures weight, not size: "A carat is a standard unit of weight for a diamond and is equivalent to 200 milligrams (1/5 gram)," under the FTC's Jewelry Guides (16 CFR 23.18). A 3.41 ct TW pavé heart is many small lab-grown diamonds adding up to 3.41 carats, so it will look different from a single stone of the same weight.
Yellow gold or white gold?
Match what you already wear. Our 0.30 ct TW pendant is 14k yellow gold, warm and classic; the M pendant, the pavé hearts and the tennis necklace are 14k white gold, which keeps the look bright and icy. If you layer necklaces, keeping the metals consistent usually looks most intentional.
Is the chain included?
Check every listing. Our two smaller pendants come with a matching chain, ready to wear. The 3.41 ct TW pavé heart is sold as the pendant only, so you can choose your own chain. The tennis necklace and the heart with its tennis chain are complete at 17 inches.
Make sure it says lab-grown
Whatever you buy, the stone should be named for what it is. Federal guidance requires "laboratory-grown," "laboratory-created" or a phrase of like meaning immediately before the stone's name (16 CFR 23.25). Every diamond in our catalog is lab-grown and labeled that way. For the background, read are lab-grown diamonds real diamonds?
