About lab-grown pink sapphire

A lab-grown pink sapphire has the same makeup as a natural pink sapphire: corundum, rated 9 on the Mohs hardness scale, second only to diamond. That makes it a sturdy choice for an engagement ring or a ring worn every day. The heart shape shows the pink most strongly toward its center. Prongs at the point and on the two lobes hold the shape securely, and a bezel wraps the outline in metal.

Lab-grown pink sapphire heart engagement ring styles

  • Solitaire: one heart-shaped lab-grown pink sapphire on a plain or slim band, some with a bypass or wide flat band.
  • Pave and side stones: lab-grown diamond accents along the band, or baguette and pear side stones next to the center.
  • Halo and double halo: one or two rows of lab-grown diamonds around the heart, which make it look larger.
  • Three stone, vintage and floral: side stones that frame the center, milgrain and filigree details, or petal shapes.

A halo or pave band gives you a lab-grown pink sapphire heart ring with lab-grown diamonds, where the white accents make the pink look brighter.

Metals, carat weight and price

Gold designs come in 10K, 14K or 18K. Rose gold matches the pink for a soft, warm look; white gold, platinum and silver give more contrast, so the pink stands out. Carat weight is picked on the product page, from 1 to 9 carats total weight. Prices start under $300, and most rings are between about $750 and $1,050 at their smallest option.
