Gemstone # OpalEth273 Name: Opal Locality: Ethiopia Weight: 2.73 carats Size: 12.77 x 9.16 mm Price per Carat: $ 80.00 Price For Stone: $ 218.40

Cut: Modified Pear Color: Orange w/ "Contra Luz" Color Flash Clarity: Eye Clean Cut by Us: No Availability: Available

Comments: Recently, some very fine Fire Opal gems have been coming out of Ethiopia. This stone has a strong "Contra Luz" effect which is a vibrant multi-color flash that appears like "rainbows" within the gem when it is backlit. The term "Contra Luz" translates to "against the light" in Spanish, and only a very small percentage of Opals show this effect. The quantity of these Ethiopian stones certainly seems to be limited, and fine quality gems are few and far between.
