How to use this prompt

"A central marquise diamond flanked by baguette-cut stones in a stepped pattern" is the Art Deco signature that distinguishes this necklace from a generic diamond pendant — the stepped geometry is the defining composition of the style. "Marquise" and "baguette" are the cut names that tell Midjourney to render specific stone shapes rather than generic sparkles. "Hand-drawn technical illustration style with fine ink linework and subtle graphite shading" is the technique that produces a jewelry design drawing, not a product photograph. "A blank rectangular panel at the bottom for the necklace name and metal weight" is the functional panel that makes this a design card. Stylize 200 holds the geometric precision clean.

Variations to try

  • Swap the platinum for yellow gold with an onyx centrepiece instead of diamond
  • Change to a collar necklace with a continuous line of channel-set baguettes
