The clarity of a gemstone refers to its inclusions, small natural interior characteristics that a gemstone may contain.
To mesure it, we at Sparkl Trade have established 4 categories, beyond which we do not select and offer stones.
Loupe Clean: The gemstone is free of inclusions with a 10x loupe.
Eye clean: The gemstone is free of inclusions visible to the naked eye, but not necessarily at 10x magnification.
Slightly included: Inclusions are slightly visible to the naked eye, but do not affect the brilliance and beauty of the gemstone.
Moderately included: Inclusions are visible to the naked eye, reflection of light and/or color is slightly inhibited.
This analysis is carried out by our gemological experts at the time of the selection of the stones. Some gemstones such as emerald are naturally included, we talk about a garden in the heart of the stone, these are the signs of the uniqueness of the stone and proof that it is natural.
In jewelry, treatments are necessary on some gemstones to enhance their natural beauty, bring out their color and reduce inclusions.
At Sparkl Trade, we only accept natural and commonly accepted methods of treatment in jewellery:
Heating: this is a technique used on many gemstones and consists of reproducing the action of the earth on the gemstone: the gemstones are exposed to a strong heat, which naturally changes their colour and strengthens them.
The oiling of emeralds: Emeralds are naturally included, so they are soaked in baths of colourless oil to fill the cavities (mostly cedar oil).
We also offer untreated gemstones. It is important to note that untreated gemstones are more expensive as they are rarer.
We guarantee a secure delivery of your gemstone within 5 to 8 days in the UE, thanks to our partners : La Poste, FedEx, DHL and Ferrari.
The delivery is free, wherever in the world you are!
We send your gemstone discreetly in an unmarked package that you can track with a tracking number.
If you need to add an additional certificate, the sending time may be extended depending on the laboratory and its capacity to process your request (1 to 8 additional days).
We do our best to ensure that the gemstone meets your requirements, however, if you change your mind, you can request a return up to 7 days after receiving your order.
However, there are no guarantees for damage to the gemstone after receipt. The gemstone must never be assembled or altered before being returned. Any alteration of the gemstone forces the possibility of returning the gemstone, a check upon receipt of the return will be systematically carried out.
Returns are free of charge at the rate of 2 per month, beyond this limit, returns will be fixed at 50€.
All our gemstones from Bangkok and Sri Lanka are systematically delivered with a certificate (ICA or FGL). For the gems from Paris, the certificate can be provided in extra if it is not available.
You can check the authenticity of the ICA memo card certificate with the following link:
However, some gemstones are already certified, but do not hesitate to request additional certificates from other laboratories in order to obtain full information about your gemstone. If you want information about the processing or the exact origin of the stone, you can request an additional certificate attesting to information other than the authenticity of the gemstone.
When the gemstone is already certified, we do not systematically add an ICA certificate, in this case you can ask for it. If you wish to have an additional certificate or change the laboratory, please contact us.
