DESCRIPTION: FreeForm carved Fire Mexican Opal 13.60 Carats. 

Item Type: SOLID NATURAL carved opal 

This is a hand carved opal from Magdalena Jalisco. 

Old Auction ID: 321639

Origin: MEXICO 

Opal Size: 18 x 13.5 x 8.5 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, with attractive face up and eye appeal. Custom cut about 9 years ago from rough well seasoned and so very stable, stone approx. 18 x 13.5 x 8.5 mm. Valuable opal variety.

Photo taken with an ordinary digital camera with a ray of sunlight entering stone from behind at at a slight angle to best show fire. Color has not been enhanced - but note that rainbow fire is NOT VISIBLE in ordinary lighting.
