By Lavora Diamonds, Provo, Utah. Updated October 2026.

A hidden halo is a thin ring of small diamonds set under the center stone. It adds sparkle from the side without changing the top view. Our default center is D–E color with VS1+ clarity, quoted on the exact stone you choose. Desk rates are per carat, not per shape, so an oval, round, cushion or any other 4 carat shape of the same grade prices the same. On our ring price estimator, a 3.5ct D–E/VS1+ hidden halo in 14K yellow gold is $3,200–$3,525, a 4.0ct D–E/VS1+ hidden halo is $3,225–$3,775, and a 5.0ct D–E/VS1+ solitaire is $4,475–$4,950. A pavé band, 18K gold or platinum move the number up, and your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is a 4 carat center?

The hidden halo sits below the center, so the top view is set by the center stone. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
4ct round	about 10.2–10.4 mm across
4ct oval	about 12.6–13.4 mm long, 8.8–9.0 mm wide
4ct elongated cushion	about 10.5–11.8 mm long, 7.9–8.3 mm wide

We confirm the exact millimeters on the stone you choose before production, and you see the hidden halo from the side in your 3D render.

Buying tips

• Clarity: VS1+. At 4 carats the table is large, and VS1 is our floor.
• Color: D–E keeps a 4 carat center bright and matches the small halo diamonds, especially in white gold or platinum.
• Shape: a hidden halo works under an oval, round, cushion, pear, radiant or emerald. Desk rates are per carat, not per shape.
• Other builds: see the hidden halo price guide and 4 carat ring prices.
