Buying guide

How a bypass ring is shaped

In a bypass ring the band does not meet in one straight line under the stone. Its two ends wrap past the center from opposite sides, giving the ring a gentle swirl. The lab-grown ruby sits in that curve, framed by the moving metal. The look is softer and more organic than a classic straight band.

Choosing a style

  • Solitaire: most designs keep the band plain, polished or wide and flat so the red stone stands out.
  • Leaf and floral: some add sculpted leaves, one with pave.
  • Accented: a few add lab-grown diamond side stones, channel set accents on a split shank, or a bezel around the center. These make a lab-grown ruby and lab-grown diamond bypass ring.

Carat weight, metal and price

Every design offers 1 to 9 carats total weight. Lab-grown ruby rates 9 on the Mohs hardness scale, so it holds up well to daily wear. Gold comes in 10K, 14K or 18K; yellow and rose gold warm the red, while white gold and platinum give it a crisp contrast. Bands run from about 1.8 to 4 mm wide. Prices start under $350, and most rings are between about $800 and $1,000.
