You need to take it to a jeweler. He has a little gadget that he can use that will tell if it is a diamond or not. This is very simple and fast and takes about two seconds to do. Otherwise there is not a good way to tell one by just looking at it. They make these diamonds in a similar way that nature does and the only difference is that it came from a factory and a real diamond comes from a mine.
Every diamond is a pure diamond: pure carbon.
Carbon
Creating a synthetic diamond can take anywhere from several days to a few weeks, depending on the method used and the size of the diamond being produced.
About 10 carat rough yellow diamond was produced by diamond manufacturer in Russia, St-Petersburg
Synthetic diamond is produced in a process; as opposed to natural diamond, which is created in geological processes. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, denoting the production method, High-Pressure High-Temperature synthesis, respectively.
The field test for a raw stone is 'extreme hardness'. A faceted and cut diamond can be verified by the use of a probe, which a jeweler can use to recognize a diamond.
A natural diamond is formed over millions of years under the Earth's crust, while a synthetic diamond is created in a laboratory environment. Bestingems offers a range of natural and synthetic diamonds, each with unique qualities to suit different preferences and budgets.
Diamond mines in Central & South Africa are where 50% of non-synthetic diamonds come from.
A synthetic diamond is a mineral made of carbon, and possesses all the same properties as a mined diamond. It has a cubic crystalline structure, a refractive index of 2.42, dispersion of 0.044, mohs hardness of 10 and a density of 3.52.
Diamond Nexus offers both synthetic diamonds(made with pure carbon) as well as diamond simulants that are not made with pure carbon, but are nearly identical to a natural diamond besides having different elements. The pure carbon gems are only available in a canary color though.
Ruby has a hardness of 9 on Mohs scale of hardness . So any gemstone with hardness more than 9 would scratch a ruby and that includes, diamond, synthetic moizzanite and synthetic diamond.
Only if they are imported or synthetic. Diamonds do not occur naturally in the Philippines.
