Small in scale. Big in intention.The Heart Key Pendant Small Diamond transforms a classic key into a modern, kinetic jewel. A double concentric halo frames a single floating round diamond, while the key tooth becomes a sculpted heart—an elegant detail that replaces tradition with meaning. The result is light, contemporary, and unmistakably emotional without being sentimental.

Designed for jewelers and professional designers, this Heart Key Pendant Small Diamond 3D model balances visual movement with production logic. The rail / semi-bezel seat allows controlled diamond motion, the concentric rings maintain structural stability during casting, and the compact proportions make it ideal for petite pendants, charm collections, and layered necklace lines.
