To determine the blemish or the particular inclusion in the diamonds, they are viewed under 10x magnification under controlled lighting. According to the GIA Clarity Grading System a diamond can be graded in 11 diamond clarity ratings or grades that range from flawless or internally flawless(FL or IL), VVS1 and VVS2 (Very, Very, Small inclusions), VS1 and VS2 (Very Small), SI1 and SI2 (slightly included), I1,I2 and I3 (Included diamonds). Many of these characteristics are visible to the naked eye, especially in the case of included diamonds, while flawless diamonds do not show any problems even under the magnification.
Diamonds are a metastable allotrope of carbon. In them, the carbon atoms are arranged in a face-centered cubic-crystalline structure, known as diamond lattice. There exists a strong covalent bond between these atoms. This makes diamond the hardest as well as the most thermally conductive material in the world. Diamonds are rated 10 (hardest) on the Mohs scale of mineral hardness. The most sought-after diamonds are the colorless ones. They are completely free of impurities, and are made of pure carbon atoms.
Natural diamonds are always associated with some irregularities and imputities in their structure, which impart color. A pure natural diamond is colorless and very rare. In comparison to this, synthetic ones are flawless; rather structural imperfections are imparted in order to simulate the natural ones. Synthesizing colored varieties of these gems, is far cheaper than producing colorless diamonds, as the former ones take less time to grow.
Merging: If you want to merge an old ring that is possibly a heirloom, with a new one, then remounting may prove helpful.
