Question 1

What is a diamond pendant?

Accepted Answer

A diamond pendant is a piece set with one or more diamonds that hangs from a necklace chain. Most pendants slide onto the chain through a small loop called a bail, so you can move one to another chain. Common styles are a single diamond (solitaire), a halo, a cluster, a heart, a cross or an initial.

See all lab grown diamond pendants.

Question 2

How big is a 1 carat diamond pendant?

Accepted Answer

A round 1 carat lab grown diamond is about 6.5 mm across, roughly a quarter of an inch, and clearly visible at the collarbone. Half a carat is about 5.2 mm and 2 carats about 8.1 mm. On halo and cluster pendants the carat weight is a total, so each diamond is much smaller.

1/4 ct: about 4.1 mm
1/2 ct: about 5.2 mm
3/4 ct: about 5.9 mm
1 ct: about 6.5 mm
1 1/2 ct: about 7.4 mm
2 ct: about 8.1 mm

These are median sizes of certified round lab grown diamonds (H color and VS2 clarity or better) listed for sale in September 2026. For one diamond on its own, see our diamond solitaire pendants.

Question 3

Solitaire, halo or cluster — which pendant looks biggest?

Accepted Answer

For the same total carat weight, a halo or cluster pendant covers more area than a solitaire. A halo circles the center diamond with small ones, so the face looks wider. A cluster groups small diamonds to read as one larger shape. A solitaire puts all the carat weight into one diamond, for a cleaner look.

Compare solitaire pendants, halo pendants and cluster pendants.

Question 4

Will a pendant fit a chain I already have?

Accepted Answer

Usually, if the chain is fine. The chain's clasp and end must pass through the pendant's bail, the loop at its top. Fine cable, box and wheat chains of about 1 to 2 mm usually fit. A thick rope or wide chain may not, so compare the bail's opening with your chain before you order.
