Lab-grown pink sapphire has the same chemistry and hardness as natural sapphire: it rates 9 on the Mohs scale, second only to diamond, so the side stones stand up well to everyday wear. The soft pink color adds warmth beside a colorless center without taking attention from it. Lab-grown sapphire is the September birthstone, a nice touch for a September birthday or anniversary.
Most designs set the lab-grown pink sapphire as side stones along the shoulders or the band, and many add pave. You will also find solitaires with lab-grown pink sapphire accents, a few three stone settings, hidden halo and halo designs, and settings with marquise or pear side stones. Where a design adds diamond accents, they are lab-grown diamond accents.
You choose the center diamond and its shape in the next step. The price shown is for the setting; the center is priced when you choose it. Settings start under $250, and most are between about $600 and $950. White gold, platinum and silver keep the lab-grown pink sapphire color crisp and cool, while yellow and rose gold warm it up and make the side stones stand out against the metal.
