A one-of-a-kind piece inspired by Jillian's trip to Marrakech. A 3.26ct tanzanite heart flashes deep violet between two freeform boulder opals (3.66tcw), all set on a domed band of rich berry enamel in 14k yellow gold. Moody, bold, and utterly captivating. There's only one.

Please note: resizing this ring adds an extra 7–10 days to delivery.

Jillian's Design Notes:

Back in the fall of ‘24, I went to Marrakech, and it completely blew me away. It felt like living in high definition: the spices, the sounds, and especially the colors were impossibly bright and saturated.

My friends and I would spend hours exploring the Medina each day, and by night, my whole body would still be buzzing. I don't think I fell asleep before 2 or 3 AM once the entire trip.

Two years later, that color sensory overload hasn't left me. I’ve spent the last year working on a new line of rich, deeply pigmented enamels inspired by that exact trip. My goal was to turn those memories into pieces that are bold, playful, and unforgettable.

  • 14k Gold: Our 14k gold pieces can last a lifetime with proper care. Featuring recycled gold whenever possible, our 14k gold pieces are durable enough for everyday wear.
  • Tanzanite: Tanzanite is celebrated for its stunning blue to violet hues, often showcasing a mesmerizing trichroic effect. Symbolizing transformation and insight, this rare gemstone was discovered in the 1960s near Mount Kilimanjaro in Tanzania, making it a cherished treasure.
  • Opal: Opal, known for its stunning play-of-color, displays a mesmerizing range of hues from fiery reds and oranges to cool blues and greens. Symbolizing inspiration and creativity, opal is believed to enhance imagination and bring emotional balance to its wearer. Opals are found in various locations worldwide, including Australia, Ethiopia, Mexico, and the United States.
  • Enamel: Enamel is a smooth, glass-like coating fused to metal, adding both color and protection to jewelry. We love the glass-like finish it can create on a piece.
