Oval Cut Diamond Engagement Ring With Octagon Shape

This fancy colored diamond ring blends bold vintage elegance with modern strength, featuring a striking oval black diamond engagement ring crafted in a refined signet engagement ring silhouette. The oval lab grown diamond is secured with a dramatic 12 claw prongs setting, creating a confident high-profile look while keeping the center stone protected for long-term wear. With its bold face and sleek proportions, this design also gives the feel of octagon shaped engagement rings, offering a strong geometric presence that stands out from traditional styles.

Designed with a split shank oval engagement ring structure, the ring creates a powerful statement while maintaining a slim, wearable fit through its 1.8 mm band engagement ring base. The double shank engagement rings style adds depth and stability, making it ideal for those who want a structured look without heavy bulk. From the back view, the hollow engagement ring detail keeps the design airy and comfortable, while also allowing more light flow and making the ring easier to wear daily.

Set in yellow gold, this lab grown diamond engagement ring carries a strong symbolic meaning—black diamonds represent resilience, power, courage, and transformation, often linked to protective energy and inner strength. Paired with yellow gold, the contrast creates a bold luxury aesthetic, making it a perfect alternative to traditional white diamonds and a stylish option for those who love vintage black diamond engagement rings, onyx rings for women, or modern signet rings for women. With a bold 4.25 carat diamond ring presence and a sleek slim signet ring finish, this piece is made for someone who wants a confident, statement-making love story.
