Deep purple. Black onyx contrast. A split shank that belongs in a different era.

This amethyst engagement ring centers a marquise-cut lab-created purple amethyst in a secure prong setting on a split shank band adorned with round black onyx accents — a design that channels Art Deco boldness with a dark, gothic edge. The elongated marquise silhouette flatters the finger while the black onyx side stones create a striking color contrast against the deep purple amethyst and warm metal. Available in gold plated, sterling silver, or black rhodium for a fully dark aesthetic. Handcrafted in Jaipur.

Why Marquise Cut?

The marquise cut — an elongated oval with pointed ends — is one of the most flattering gemstone cuts for a ring. Its elongated silhouette makes the finger appear longer and more slender, and it creates a larger visual surface area than a round stone of the same carat weight. In deep purple amethyst, the marquise cut creates a bold, directional presence that's completely unlike a traditional round solitaire.

The Black Onyx Contrast

The round black onyx accents along the split shank create a dramatic color contrast — deep black against vibrant purple against warm gold (or cool black rhodium). This combination draws on Art Deco jewelry's love of bold color contrasts and geometric precision, while the gothic edge of the black onyx gives the ring a dark academia quality that's entirely its own.

Black Rhodium Option

For a fully dark, gothic aesthetic, choose the black rhodium finish — a dark, reflective metal coating that turns the entire ring deep black, creating a monochromatic look where the purple amethyst becomes the only point of color. It's a striking, unconventional choice that makes this ring genuinely unlike anything else.

Lab Amethyst & Black Onyx — Ethical & Beautiful

Both stones are lab-created — sharing the same optical and physical properties as their natural counterparts, ethically sourced, conflict-free, and significantly more affordable without any compromise on color or quality.
