what is the difference between gem grade and industrial grade diamonds?
72993
Gem-quality diamonds are the most perfect diamonds, with minimal impurities and defects. They have a specific gravity that is very close to 3.52. Industrial diamonds are mostly used in cutting, grinding, drilling, and polishing procedures.

VVS diamonds have miniscule inclusions that are difficult even for trained eyes to see under 10x magnification. VVS2 clarity diamonds have slightly more inclusions than the VVS1 grade. A VVS diamond is an excellent quality diamond and clarity grade.

What is the difference between lab diamonds and cubic zirconia? Quite simply, a laboratory-grown diamond is a diamond: carbon atoms arranged in a diamond cubic crystal structure. ... In fact, a cubic zirconia contains zero carbon, whereas diamonds (mined and grown) are made entirely from carbon.

As a general rule, an EGL certified diamond will compare equally in quality to a GIA certified diamond that is graded two color grades and one clarity grade lower. For example, an EGL diamond graded G in color and VS2 in clarity is comparable to a GIA diamond graded I in color and SI1 in clarity.

A little research indicates that while natural diamonds may slightly vary in hardness (the impurities which alter the color also modify its crystal properties), synthetic diamonds have a more consistent hardness which is otherwise identical to a naturally-occurring diamond with the same chemical properties.

Emeralds are actually a fairly hard gemstone when measured on the Mohs scale of hardness. Diamond is a 10, corundum is a 9 and beryl (the gem family that emerald is from) is approximately an 8. ... Diamond is approximately 90 times harder than sapphire. There is also some variation within the same material.

In terms of their definitions, there are some difference between VS1 and VS2 Diamonds. ... While VS2 diamonds are usually eye-clean, some outliers exist, especially in larger-sized stones like 3, 4 and 5 Carat diamonds. These outliers often barely make it past the SI1 grade and contain inclusions visible to the naked eye.

Cheaper than round diamonds. Oval diamonds are more affordable because they're less in demand. ... These diamonds have the same characteristics in carat size (1 carat as the benchmark), color (H), and clarity (VS2). Note: A cut grade is the one big difference between round diamonds and ovals.

Real diamonds occur naturally in nature whereas American Diamonds (also known as Cubic Zirconia) are the crystalline form of zirconium dioxide (ZrO2) which are man-made in a lab. ... Ideally, a real diamond should not have scratches on its surface.

Quite simply, a laboratory-grown diamond is a diamond: carbon atoms arranged in a diamond cubic crystal structure. ... Grown diamonds and mined diamonds have the exact same physical properties. A cubic zirconia is not a diamond.

They have the same properties as natural diamonds, the only difference is that they are grown in a lab, whereas natural diamonds are formed in the earth. Synthetic diamonds are alternatives to natural and lab grown diamonds.

Diamonds are isometric whereas quartz is hexagonal. Both of them have the transparency scale of transparent to opaque. The gravity of diamond is 3.1-3.5 whereas quartz have 2.6 '“ 2.7. Diamond is adamantine with greasy luster whereas quartz can have vitreous, resinous, adamantine and dull luster.

Type II diamonds have no measurable nitrogen impurities. Type II diamonds absorb in a different region of the infrared, and transmit in the ultraviolet below 225 nm, unlike Type I diamonds. They also have differing fluorescence characteristics, but no discernible visible absorption spectrum.

FL (or Flawless) is the highest grade for clarity. An FL diamond has no imperfections even when magnified 10x by a professional. For color, D or completely colorless diamond is the highest grade. While flawless and colorless diamonds are extremely rare, cut determines a diamond's true value.

In fact, a cubic zirconia contains zero carbon, whereas diamonds (mined and grown) are made entirely from carbon. Put another way, cubic zirconia is a cheap imposter to a diamond that is a different material entirely; whereas a synthetic diamond is chemically and optically identical to a mined diamond.

As a general rule, an EGL certified diamond will compare equally in quality to a GIA certified diamond that is graded two color grades and one clarity grade lower. ... Due to the discrepancy in the grading standards used, an EGL diamond graded the same color and clarity as a GIA diamond will be less expensive.

There is no visual difference in Lab Created Diamonds vs Natural Diamonds. They sparkle the same, have the same types of color and clarity, and can come in the same sizes and shapes. Likewise, Lab Grown Diamonds are just as hard as Natural Diamonds.
