This is a stunning faceted

Origin: MEXICO

Opal Size: 18 x 14 x 12 mm. APPROX


Treated/Untreated: Untreated.

PLEASE NOTE: With the contra luz variety of Mexican opal the internal rainbow colored fire is best viewed in transmitted light ( light entering stone from behind), rather than reflected light ( light shinning on stone from in front) and although with some stones of this variety rainbow fire may be visible in reflected light, the fire is NOT VISIBLE in ordinary lighting.

This stone will display nice internal rainbow colored fire when viewed with strong direct transmitted lighting, lightly visible in direct reflected lighting, but best viewed with light source entering stone from behind, such as from a ray of sunlight or even by holding stone up to an ordinary lamp light and moving stone back and forth. Transparent, near eye clean with small dark base of pavilion spot, free of crazing, with attractive face up and eye appeal. Custom cut about 4 years ago from rough well seasoned and so very stable,
