emerald jewellery The deep, distinctive colour of an emerald is one that almost everyone knows. This kind of green cannot be matched, and leads to a truly mesmerising stone. But what should you look out for when purchasing an emerald ring? We have put together some helpful tips that should point you in the right direction.

The Colour

First, and definitely foremost, is the colour. Like all gemstones, Emeralds are judged on the depth of their colour. The deeper and richer the tone, the more expensive you can expect the stone to be. An emerald is judged for its place on a scale between yellow-green and blue-green. A blue-green emerald is most desired; its deeper, more intense colour is truly something to behold. Most of the emeralds that are on the market today are Colombian, and that's good news; emeralds from this corner of the world tend to be more blue than yellow. Zambian Emeralds are also available to you at a more affordable price than their Colombian counterparts. These stones offer spectacular hues and high quality stones that won’t break the bank. It is for this reason that we typically offer Zambian Emeralds. Generally speaking, three categories of colour that emerald’s are assessed for: hue, tonal grade, and saturation. This criteria evaluates emeralds based on the depth of their colour. And as you can expect, the deeper the green, the more desirable the stone is.

The Clarity

The clarity of an emerald cannot be evaluated in the same way as other gemstones. This is because these gems almost always come with inclusions (small specs of crystal or dirt that are encased in the gemstone). In fact, around 99% of all emeralds mined have these inclusions, and you would be hard-pressed to find one that doesn't. Despite this, too many inclusions in an emerald and the stone will start to drastically reduce in quality. An excess of these additions can mean that your emerald is more brittle than it should be, or simply not as beautiful. When picking out your emerald ring, it is important to note that you may have to settle for a stone that is not completely clear. However, this doesn’t mean that your gem will automatically be laden with hundreds of impurities. As is true with all gemstones, it is simply important to find the right balance for you.

The Cut

When it comes to the cut of an emerald, it is once again all about the colour. Cutters must make sure that the emerald they are working on doesn't become too shallow, or break altogether. It is your choice what cut you would like to be produced. But take the advice of the professional you are working with, and make sure that they know exactly how to offer you the shape you would like without damaging the stone.


Because of how important the colour of an emerald is, it is not uncommon for them to be treated to enhance their colour. Resins and oils are most often, and produce a much brighter tone. These treatments are not only used to improve the colour of your stone, they are also used to fill in some surface-level imperfections. When it comes to this, resin and oil react differently in the long term. Untreated emeralds elicit the highest prices, but this doesn’t mean that a treated stone cannot be everything you are looking for. It is simply a question of making sure you have what you’ve paid for.
