Buying guide

How a hidden halo sits under the lab-grown sapphire

A hidden halo is a row of small lab-grown diamonds set around the base of the center stone, just below where it sits. From the top the lab-grown sapphire looks like a clean solitaire. From the side, the halo shows as a band of sparkle under the stone. It suits anyone who wants a simple top view with a detail that shows up as the hand moves.

Band and gallery choices

  • A pave band, on most designs, carries the line of accent stones down the shoulders.
  • A thin plain band keeps the look quiet and lets the color of the hidden halo lab-grown sapphire ring lead.
  • Some designs add vintage details such as milgrain edges, a filigree gallery or engraving.

Band widths run from about 1.8 to 2.5 mm, and 2 mm is offered on most designs.

Choosing color, size and metal

Lab-grown sapphire has the same hardness as natural sapphire, 9 on the Mohs scale, so it holds up well to daily wear. Blue looks crisp in white gold or platinum; pink and yellow warm up in rose or yellow gold. Every design offers 1 to 9 carats total weight, and gold comes in 10K, 14K or 18K. Prices start at about $300, and most rings are between about $700 and $1,000.
