Featured today is a natural Colombian emerald of 1.81 carats set in 22 karat gold as a Mercury talisman ring. The classic emerald cut Colombian emerald is fully natural and has a fine early summer grass green color. What really makes this gem stand apart is the fact that not only is there excellent clarity, despite being an emerald, the gem also has a vitreous lustre, giving it that charismatic appeal!
For planetary gem therapy, the gem must be jyotish quality. For a real appreciation of the jyotish gem that you are holding in your hand and especially more so if itâ€™s an emerald letâ€™s get a little more specific â€“ emerald is a gemstone of the beryl group â€“ Beryllium Aluminium Silicate Al2Be3 (SiO3)6, to be precise.
This gemstone crystal is formed either either in the pegmatite deposits or hydrothermal veins in metamorphic environments. Metamorphic rocks are those rocks, which were once igneous or sedimentary rocks but changed over period of time into a different state due to change in pressure and temperature. (The change however is to be so intense that the rock gets melted and the chemical rearrangement is affected. For instance, Marble is a metamorphic rock that you get when heat and pressure is applied to limestone over a period of thousands of years!)
For an emerald to form, the temperature has to be in the range of 400-500 degrees centigrade and the pressure has to be about 1-3 kilobars per square inch! In other words about 7.5 to 21.75 tons of pressure per square inch! The presence of trace element chromium gives it the rich green color. (in case of the Brazilian emeralds, the color causing trace element is vanadium).
The mineral is formed within a fluid rich silicate melt that can remain liquid for a very long therefore the cooling time is very long â€“ almost 500 million years!
You may take your time to absorb that information. And we do hope that when you look at the emerald perched on your fingers the next time, you will think about what a treasure, whose life spans an era of geological time, you own!
Natural emerald/ panna is the gemstone of planet Mercury/ Budh and is used in a talisman to harness the energies of this planet.
