Buying guide

Why a channel setting works for lab-grown ruby

A channel setting sinks each stone into a track between two metal walls. The walls hold the stones by their edges, so no prongs rise above the band and the row of red looks unbroken. The smooth top is comfortable for daily wear and does not snag on fabric. Lab-grown ruby rates 9 on the Mohs scale, so it resists scratches well, and the walls add protection from side knocks.

A half eternity band

The lab-grown rubies run around the top half of the ring and the underside is plain metal. A channel set lab-grown ruby eternity ring in this half style is easier to size than a full eternity band and sits flat against an engagement ring. At 0.5 carat total weight the line of red is fine and subtle; at 1 carat total weight the stones are larger and the color reads from across a room.

Lab-grown ruby, metal and price

Lab-grown ruby is red corundum with the same chemistry as natural ruby. Yellow and rose gold give the red a warm setting, while white gold, platinum and silver make it look cooler and brighter. Gold comes in 10K, 14K or 18K. Prices start under $350 at the smallest option, and most choices sit near $900.
