Is all the Gemstones & Diamonds Tested?
All our sapphires and Gemstones are checked by a third party independent gemological lab before we add it to the stock.
We work with a lab run by a very experienced and respected Member of the German Gemological Assn, Member of the Gemological Assn Sri Lanka, and a GIA ALUMNI Assn. The data in the product page is from the report sheet we get from the lab when we bought the stone. We have no GIA lab in Sri Lanka. But you can test the stone in any GIA lab. If our lab report and the data on our website and the gemological report we sent you is not the same you can ship the stone back. We will refund your full payments and the GIA testing cost.
Some of the equipment used when testing our gems
Fourier transform infrared spectroscopy (FTIR)
FTIR (Fourier Transform Infrared Spectrometer) is now a mandatory tool in any modern gemological laboratory. It is routinely used for testing some of the most important gems such as diamond, emerald, corundum, alexandrite, jade, amethyst, amber and turquoise.
Where some of the treatments cannot be detected when viewed with a microscope, but the FTIR would give a conclusive result.
Some of the uses of FTIR Spectroscopy are as follows, 1.Determination of Heat treatment in Sapphires and Ruby Corundum’s
2.Distinguishing between Diamond and it’s imitations.
3.Distinguishing between Natural & Synthetic Diamond
4.Determination of Zircon state in Metamict or Crystalline
5.Finding out if an Emerald is Natural or Treated.
6.Distinguishing between Natural and Synthetic citrine
7.Tells us if Jade is Polymer Coated or Uncoated.
8.Distinguishing between Taaffeite, Serendibite, and Sapphirine.
9.Distinguishing between Scapolite and quartz
And more spectra…
Identify unknown materials
As early as the beginning of the last decade Raman Spectroscopy has become standard procedure in most labs.
Raman spectrometry is a nondestructive identification of gem materials, inclusions, and even fillers. Raman spectra can also be obtained from mounted gems and thus plays a convenient and accurate role in gem testing. It also plays a vital role in detecting a wide array of materials such as HPHT treated diamonds, treated jade, etc. 1.Distinguishing between a diamond and its limitations
2.Distinguishing between Amethyst and Iolite
3.Determination of Enstatite
4.Distinguishing between Garnet varieties – Grossular and Spessartite
5.Distinguishing between Polymer coated or uncoated Jade
6.Identification of Zircon in Metamict state or Crystalline state
UV / VIS plays an important role in the distinguishing varieties of Spinel’s, to find out if its Cobalt Spinel, Iron Spinel or Chromium component Spinel from its spectra. Also, helps in finding out the state of Sapphire Corundum’s in the Metamorphic or Magmatic state, and much more.
