Lab-Grown Diamond Engagement Rings, Made for You

Every Octa Pearl engagement ring is made to order around a lab-grown diamond. Lab-grown diamonds are diamonds: they share the same chemical, physical and optical makeup as mined diamonds, so the sparkle and hardness you expect are all there. What changes is where the stone begins, and how much room that leaves you to choose the size and design you really want.

Start With a Shape, Then a Setting

Most people begin with the center stone. A round brilliant gives the most classic sparkle, while elongated shapes like oval and pear look longer on the hand and can make fingers appear slimmer. Next comes the setting. A solitaire keeps all the attention on one diamond, a halo frames it with a ring of smaller stones, and three stone and pavé designs add sparkle along the band. If you love a bit of history, vintage-inspired details such as milgrain and engraving are worth a look.

Choose 10K, 14K or 18K yellow, white or rose gold, or platinum. Each ring ships free and insured in the US, comes with 30-day returns and free resizing, and you can request a free ring sizer before you order.
