The Heart Key Pendant Necklace 1CT Diamond doesn’t try to be subtle.

It chooses impact.

A Shape People Recognize. A Scale They Remember.At the center sits a 6.4 × 6.4 mm heart-cut diamond, weighing approximately ~0.98 CT—functionally a 1 carat presence.

It doesn’t sit inside the design.It defines it.

The surrounding open heart frame is not decoration—it’s restraint.It gives the stone space to breathe, and more importantly, to dominate.

Form That Builds a StoryAbove the heart, a round-cut diamond (2.4 mm) acts like a crown jewel—small, precise, intentional.

Between head and shaft, symmetrical fleur-de-lis scrolls introduce rhythm and transition.They soften the structure without weakening it.

The shaft remains clean.The tooth resolves into a heart-shaped key tip.

Beginning and end speak the same language.
