Description
Diamond Halo Round Key Pendant Necklace 3D Model
Sometimes luxury isn’t subtle.
Sometimes it shines from every angle.
The Diamond Halo Round Key Pendant Necklace was designed to do exactly that. Twelve brilliant round diamonds form a glowing halo around an open circular medallion, turning a simple key silhouette into a piece that radiates pure brilliance.
The effect is immediate.
A circle of diamonds.
No empty space between them.
Just light.
But for jewelry designers and manufacturers, building that kind of symmetry and stone layout inside CAD software can take serious time. Every prong, every spacing detail, every proportion must be calculated perfectly.
That’s where this Diamond Halo Round Key Pendant Necklace 3D model becomes invaluable.
Instead of spending hours constructing halo settings and refining stone alignment, jewelers receive a precision-ready CAD model prepared for rendering, prototyping, or casting.
Because the most beautiful jewelry designs shouldn’t slow down the people who create them.
Design Structure
Pendant Bail
The necklace begins with a compact rounded bail, proportioned carefully to balance the diamond halo head.
Features include:
-
smooth circular structure
-
polished metal surface
-
comfortable chain compatibility
This subtle element ensures the pendant hangs naturally while maintaining the elegant silhouette of the Diamond Halo Round Key Pendant Necklace.
Diamond Halo Disc Head
The focal point of the Diamond Halo Round Key Pendant Necklace is the striking circular head.
Instead of a traditional solid disc, the design features a four-petal clover-style openwork interior, creating a sense of lightness within the form.
Surrounding this open center is a ring of diamonds arranged in a tight halo.
Key design highlights:
-
12 round brilliant diamonds forming a continuous halo
-
minimal metal spacing between stones
-
strong prong settings for secure stone placement
The diamonds create a floral halo silhouette, delivering maximum sparkle from every viewing angle.
Diamond Details
The Diamond Halo Round Key Pendant Necklace features carefully arranged round brilliant diamonds in two sizes for visual hierarchy.
| Stone Type | Quantity | Size | Approx Carat |

| Outer Feature Diamonds | 4 pcs | 2.6 mm | approx 0.065 ct each |

This distribution creates a luxury halo effect, where the larger diamonds emphasize the four key directional points of the circular frame.
Minimalist Key Shaft
Below the halo head, the Diamond Halo Round Key Pendant Necklace transitions into a sleek cylindrical key shaft.
Design intent:
-
smooth polished metal surface
-
modern minimalist structure
-
strong visual contrast against the diamond halo
This contrast between ornate brilliance and minimal structure gives the pendant a contemporary luxury character.
Architectural Key Tooth
The pendant ends with a square grid-style key tooth, inspired by castle battlements.
Design features:
-
geometric openwork grid
-
sharp linear edges
-
bold architectural character
This finishing detail balances the elegance of the diamond halo with a structured, powerful base.
