An unusual and rare piece of Colombian emerald in the perfect deep blue-green so highly prized in emeralds, finely crafted into a very elegant timeless engagement ring.
For those familiar with emeralds, it is generally accepted in the market that emeralds are almost never eye-clean. However, this particular piece is truly an exception. It is so incredibly clear and transparent, yet displays such an intense rich blue-green colour. A rare find.
With so many various shades of greens of Tsavorites available in the market, how does one tell which colour is more valuable than others? Key factors to look out for when buying gemstones are colour, brilliance (fire) and cutting. Assuming a gemstone has good brilliance and a good cut, colour is the most important factor.
For Tsavorites, the best/optimum colours are those ranging from glass green to medium green to a deep, intense green. But not overly dark or too green to a point where the stone appears black. Colours lighter than glass green are also not the most ideal. Below (3.35ct) is a fine example of a good glass green colour, with good brilliance and good cut.
3.35ct – Glass Green Tsavorite
An example of deep, intense green (but not overly dark) with good cut but slightly lacking in brilliance is the 2.86ct below.
2.86ct: Deep intense green Tsavorite
If you are getting confused, look below for yet another example (1.77ct) of a deep, intense green Tsavorite that has moderate brilliance and moderate quality cut, but good colour.
1.65ct: Deep intense green Tsavorite (good colour), with moderate brilliance and moderate quality cut.
The “poorest” example is as shown below (2.2ct) which has a green colour that is bordering on “too dark”, somewhat lacking in brilliance and poor- moderate quality cut. However, make no mistake, even this “poor quality” specimen is considered above average quality compared to most seen in-stores or available in the mass market.
2.2ct: Dark green Tsavorite with moderate brilliance and poor-moderate quality cut.
To the unknowing eye, this beautiful green gemstone is usually mistaken for an Emerald. It is deemed a valuable gemstone not simply because of its high Refractive Index (1.72, not lacking far behind Sapphires which have an RI of 1.76) and its relative hardness (Mohs Scale of 7.25 versus that of Sapphires which is 9). Ranking high on the Refractive Index results in usually good – high brilliance if the gemstone is properly cut and faceted.
Tsavorites are usually pure and untouched by human intervention. Some gemstones require various forms of treatment, heating process, oiling to achieve a certain level of brilliance and colour. Not the Tsavorite – it is possible to find beautiful, brilliant Tsavorites that are as Mother Nature intended for them to be.
An example is this ring carefully handcrafted for client. Simple, classy, yet stunningly brilliant.
