Product Description

Sharp Corners. Clean Lines. Unforgettable Presence.

A princess cut lab-grown diamond — bold, geometric, architectural — held by four corner prongs above a 1.5mm plain band so refined it nearly disappears. The princess cut is all sharp angles and maximum brilliance, a stone that commands attention without asking for it. On an ultra-thin band, it floats above the finger with a precision that is unmistakably modern.

This is the princess cut solitaire for those who know exactly what they want.

  • Band Width: 1.5mm ultra-thin plain band
  • Metal: Solid 14K yellow, white, or rose gold
  • Total Diamond Weight: 0.40ct

Why Princess Cut?

  • The most brilliant square diamond — the princess cut has 57–76 facets engineered to maximize light return; it rivals the round brilliant in fire and scintillation
  • Bold and geometric — the sharp square corners create a distinctly modern, architectural silhouette unlike any other diamond shape
  • Appears larger than its carat weight — the square shape has exceptional surface area relative to its carat weight
  • The #2 most searched engagement ring shape — consistently second only to round brilliant in global search volume

Why Ultra Thin Plain Band?

  • All stone, no distraction — the 1.5mm plain band lets the princess cut's sharp geometry speak for itself
  • The corners float — on a thin plain band, the four sharp corners of the princess cut appear to hover above the finger with no visible support
  • Stackable — pairs beautifully with plain or pavé wedding bands on either side
  • Timeless — no trend, no gimmick — the princess solitaire is a forever ring

Why Lab-Grown?

  • Chemically, physically, and optically identical to mined diamonds
  • Ethically sourced — zero mining impact
  • Exceptional value — significantly more diamond for the same budget as mined
