The Midnight Crest ring - Architectural Black Opal Statement Ring (2.67ct) in 18K Gold
Black opal framed in luminous gold — a bold, elemental statement.
Specifications & Materials
- Stone: 2.67 carat Australian Black Opal (N1-N4 body tone).
- Metal: Solid 14K yellow gold
- Setting: High-security Basket with architectural prongs.
- Dimensions: Ring face ~12mm × 10mm oval cabochon.
Design & Origin
- Concept: A bold, architectural statement ring designed to be an enduring emblem of confidence, featuring strong metal lines to complement the stone's intensity.
- The opal is bezel-set in 18K gold, giving the piece clarity of shape and a sense of anchoring weight. The smooth, uninterrupted border of metal creates a subtle crown effect — less ornamental, more architectural.
- Opal type: The dark body tone acts as a deep velvet canvas, amplifying the "electric" flashes of red, green, and blue color play.
- Origin: Exclusively sourced by Vinca from Lightning Ridge, Australia, renowned for yielding the world’s most valuable Black Opals.
Craftsmanship
- Features a sculpted setting fabricated to perfectly cradle the rare opal cabochon.
- The ring's substantial design and structure ensure it is balanced and durable for its role as a statement heirloom.

What Our Clients Think
I had a wonderful experience at Vinca Jewelry today. I came in to get my wedding rings resized, expecting to pick them back up in a week or so. Not only did they finish them the same day but they were ready only 1.5 hours later and as sparkling as the first day I put them on.
Kloe LeFevre
Wonderful Experience!
Amazing service with a real family atmosphere. The team was friendly and caring, and they did a beautiful job repairing my jewelry. Great selection, fair prices, and people you can trust. Highly recommend!
Louis Aguilar
Although I live out of state, there is no one I trust more to repair my jewelry than Vinca. Vinca would not settle for a stone that did not quite match my ring, and waited until the proper stone could be found. That kind of care and expertise is priceless!
Amy Kumagai
There’s no other place I trust than Vinca. I bought my wife’s engagement ring and our wedding bands at Vinca and we just celebrated our 18th anniversary. My wife needed her ring resized and cleaned and even though we no longer live in the Kansas City area, we wouldn’t think of taking it anywhere else. Highly recommend Vinca to all. It is a treasure of the Country Club Plaza.
Jonathan Kelley
The staff at Vinca are so lovely and helpful and not pushy!! They encouraged us to walk around the Plaza and think on our purchase, offered to clean my existing ring, and were just a genuine pleasure. We found a very unique a perfect ring for my fiancée and I couldn't be happier with the experience.

Common Questions
Most Vinca pieces are made to order. This allows us to focus on proportion, detail, and finish rather than volume. If a piece is in stock, timelines may be shorter — we’ll confirm once you inquire or place an order.
Production typically takes 4–6 weeks, depending on the piece and any customization. For engagement rings or bespoke work, timelines may vary slightly based on stone sourcing and design complexity.
Yes. Many pieces can be customized in stone choice, metal, or proportion. Some designs are more flexible than others — if you’re unsure, reach out and we’ll guide you honestly.
We do. Bespoke pieces begin with a conversation and are designed from scratch at the bench. If you’re looking for something entirely personal, this is often the right path.
We work primarily in solid gold and platinum, using natural and lab-grown stones depending on the project. Material choices are always discussed with care and transparency.
If you don’t know your size, we can help. We offer guidance, sizing options, and resizing where possible. For engagement rings, this is very common.
Most rings can be resized within a reasonable range. Some designs or materials may have limitations — we’ll always flag this upfront.
