Rutile (Synthetic) Gemstone & Information | Gemopedia by JTV | Gemopedia™

Rutile (Synthetic)

Synthetic rutile can be produced synthetically by either the Czochralski method or flame fusion method. Because of rutile's high refractive index, it was used as an early diamond simulant. However, it is rarely used today as such because of its low hardness. Synthetic gems have the same chemical, optical, and physical properties of their natural counterparts, but are a more cost-effective alternative to a natural gem.
