Buying guide
A solitaire puts the lab-grown blue sapphire on its own, so the color carries the ring. A halo surrounds it with lab-grown diamond accents, which brighten the blue and make the center look larger. A three stone ring sets a lab-grown diamond accent on each side. Many designs here are solitaires, and many others are halo or side stone rings.
Most designs pair the center with a pave band of lab-grown diamond accents, the classic lab-grown blue sapphire platinum ring with accents. Some add a split shank, a twisted or bypass band, or vintage milgrain and filigree. Plain bands keep the look simple.
Every design offers 1 to 9 carats total weight. Platinum's white tone sets off deep blue, and it holds prongs firmly for daily wear. A lab-grown sapphire is 9 on the Mohs scale, with the same hardness as a natural sapphire. Rings start from about $1,050 at their smallest option, and most are between about $1,700 and $1,950.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
