Buying guide
A halo is a ring of small lab-grown diamonds around the center stone. It makes the lab-grown sapphire look larger and adds sparkle around the color, which helps darker blue stones stand out. The frame also protects the edge of the center. A lab-grown sapphire is corundum, 9 on the Mohs scale, so it handles daily wear well.
Blue lab-grown sapphire gives the classic deep look, and yellow gold makes it feel warm and rich. Pink lab-grown sapphire looks softer, and the gold brings out its warmth. Yellow lab-grown sapphire blends with the metal for a sunny, golden ring. The color is picked on the product page for each design.
Most designs are offered from 1 to 9 carats total weight. Prices start from about $650, and most rings are between about $900 and $1,000 at their smallest size.
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.
