Recently, I met this jewellery designer who just started her online shop selling jewellery.
She has a customer who asked her about the price of emeralds, and she was not sure how to answer.
She diverted the question to me. So here's my take on defining the price of an emerald.
To define the price for emeralds let's divide into 2 categories.
1. Single stones (eg. For the centre stone in a piece of jewellery )
You have to take in consideration
Carat weight : how large is the stone or the mm size of the stone
Colour: is the colour pure? Are there secondary hues? Is the colour lively and vivid? Is the colour heart catching?
Clarity: are the inclusions very distracting?
Cut: does the shape look good? Is the stone suitable for conventional setting?
Treatment: what is the extent of the treatment? What kind of treatment? Is the treatment acceptable?
Origin: is it a traditional origin stone? Is there demand for this particular origin? Does the gem display the characteristic colour and inclusions of the origin?
After you consider all these, then u think about pricing.
2. Meelees for setting
Overall make of the parcels (shape / cut of the stones)
Clarity of the parcel
Colour of the parcel
Is it a mixed parcel or straight sized?
After you consider all these, then you think about pricing.
Most emeralds have to be clarity enhanced as it is the nature of emeralds to have inclusions. Usually, emeralds that have very little inclusions tend to be very light in colour, bordering between green beryl and emerald.
The cause of colour in emerald is chromium, this is also the cause of the inclusions.
When looking at treatment of emeralds, we study the extent of the treatment, as the more cracks and fissures in the emerald, the more oil / resin would get into the stone.
At the end of the day, you should also factor in the dealer's costs to make a living. Yes there is a market price, but you have to give some room for the wholesaler for him to make his living.
