The Rare Gota De Aceite Emeralds

Obrada...

In the world of Emerald, the most sought after and rare Emerald is the Gota de Aceite Emerald. It is pronounced “go-tah day ah-say-tay”. For collects, this type of Emerald is as rare as the Kashmir Sapphire or the Golconda Diamonds. If you are ever lucky enough to see one of these Emeralds, or own one, it should be cared for like no other stone.

In Spanish, Gota de Aceite means “drop of oil”. This name was given to the finest Emeralds by the Spanish conquistadors that showed a unique and very rare pattern. This pattern has a roiled appearance that looks like oil or honey. This is why the Spanish called these fine Emeralds “drop of oil Emerald”. This same effect has sometimes been referred to as the butterfly effect.

Emeralds that originate from Columbia are generally the only stones that can show Gota de Aceite. When it was originally discovered it was thought the the Emeralds grew around Calcite precipitations which caused the roiled effect in the Emerald that gave it the oil look. However with modern gemological tools it has been discovered that Calcite is probably not the cause of Gota de Aceite. Instead it looks like irregularities in the internal crystal structure of the gemstone are responsible for dispersing the light and causing the oiled look.

Gota de Aceite Emeralds to the naked eye look like the Emerald has an oily or velvety appearance. under 10x magnification with a loupe, the roiled effect becomes more evident. Some people refer to what they see as “Whiskey in water” or “Rolling hot air”.

In the market place, sometimes gem cutters and dealers might miss a stone that shows this effect. Some novice buyers might also discard these gems for synthetics or glass. Keep an eye out for any stones you think might have this appearance and take them to a gemologist to confirm. you never know what treasures might be right under your nose.

U svijetu Emerald , najtraženiji i rijetki smaragd je Gota de Aceite Emerald. Izgovara se "go-tah day ah-say-tay". Za kolekcionare, ova vrsta smaragda je rijetka kao kašmirski safir ili dijamanti Golconda. Ako ikada budete imali sreće vidjeti jedan od ovih smaragda, ili ga posjedujete, o njemu treba brinuti kao ni o jednom drugom kamenu.

Na španjolskom, Gota de Aceite znači "kap ulja". Ovo ime najfinijim smaragdima dali su španjolski konkvistadori koji su pokazivali jedinstven i vrlo rijedak uzorak. Ovaj uzorak ima natopljen izgled koji izgleda kao ulje ili med. Zbog toga su Španjolci ove fine smaragde nazvali "smaragdnom kapljicom ulja". Ovaj isti učinak ponekad se naziva i efektom leptira.

Smaragdi koji potječu iz Kolumbije općenito su jedino kamenje koje može pokazati Gota de Aceite. Kada je prvobitno otkriven, smatralo se da su smaragdi rasli oko taloga kalcita što je izazvalo ukočeni učinak u smaragdu koji mu je dao izgled ulja. Međutim, uz moderne gemološke alate otkriveno je da kalcit vjerojatno nije uzrok Gota de Aceite. Umjesto toga, izgleda da su nepravilnosti u unutarnjoj kristalnoj strukturi dragog kamena odgovorne za raspršivanje svjetlosti i izazivanje nauljenog izgleda.

Gota de Aceite smaragdi golim okom izgledaju kao da smaragd ima masni ili baršunasti izgled. pod 10x povećanjem s lupom, efekt roiled postaje očitiji. Neki ljudi nazivaju ono što vide kao "Viski u vodi" ili "Vrući zrak".

Na tržištu ponekad rezači dragulja i trgovci mogu propustiti kamen koji pokazuje ovaj učinak. Neki kupci početnici također bi mogli odbaciti ove dragulje zbog sintetike ili stakla. Pripazite na bilo koje kamenje za koje mislite da bi moglo imati ovakav izgled i odnesite ga gemologu da potvrdi. nikad ne znaš kakvo bi ti blago moglo biti pred nosom.
