Square Octagon Frame Solitaire Halo Lab Diamond White Gold Necklace

Centered on a striking round lab diamond held by neat prongs, this solitaire halo pendant is enclosed within an elegant square octagon frame with four sharp angular points, a signature Art Deco geometric silhouette. The entire stepped octagonal border is pave-set with tiny accent stones to amplify the main stone’s glow, creating multi-layered radiant shine. Polished white gold construction pairs with a slim delicate chain that rests softly on the collarbone. Merging vintage architectural lines and timeless single-stone glamour, it works beautifully for daily layering, anniversary gifting and semi-formal occasions.
