Description

This marquise faceted imitation amethyst exhibits a light to medium purple color that mimics the rich hue of natural amethyst without its characteristic color zoning. Each stone is a synthetic spinel doublet — two layers of spinel bonded together with a tinted adhesive — making it an economical and consistent amethyst simulant ideal for jewelry production and resale.

Calibrated gemstone sizes may vary slightly ±0.10mm. Clean with warm, soapy water only. Do not apply heat or expose to direct flame, as the adhesive bonding the doublet layers may be damaged.

Features

  • Amethyst simulant with light to medium purple color
  • Composed of a synthetic spinel doublet — two spinel layers bonded with tinted adhesive
  • Mimics the rich purple of amethyst without color zoning
  • Marquise (navette) faceted cut for classic brilliance
  • Calibrated sizing for consistent use in production settings
  • Suitable for resale applications
