The elongated large marquise shape creates an elegant, light-catching sparkle that looks beautiful on its own or stacked with your favorite pieces. Lightweight, secure, and easy to wear, it's perfect for multiple piercings. Made from verified nickel-free solid gold, this piece delivers real fine jewelry quality without plating or shortcuts.

Choose your level of shine: Select your Lab-Grown Diamond Size

  • 0.30 PTS (7mm x 3.5mm): A delicate, refined sparkle that sits beautifully on the ear—perfect for minimalist styling and smaller cartilage placements.
  • 0.50 PTS (8.5mm x 4mm): Balanced brilliance with a more noticeable presence while remaining elegant enough for everyday wear.
  • 0.75 PTS (9mm x 4.5mm): Bold, eye-catching sparkle that creates a striking solitaire statement without sacrificing comfort.

Personalize Your Fit: Choose the ideal post length for your specific piercing:

  • 5mm: A snug fit for healed piercing, or thin cartilage
  • 6.5mm: The standard size for most cartilage and lobes piercings
  • 8mm: Extra room for a thicker Lobe or cartilage piercing
  • 10mm: Maximum length to accommodate swelling or thicker areas

The Estella Difference

  • Ethical Brilliance: Features a sparkling lab-grown diamond with the same beauty and brilliance as a mined diamond.
  • Forever Materials: Solid 14K gold, never plated, never filled, so it will not tarnish or fade.
  • Hypoallergenic: Nickel-free and designed for sensitive skin.
  • Handcrafted Quality: Built for daily wear, from first piercing to long-term styling.
