'Good' is a judgement and you are the judge.
A 'good' diamond could be a perfect, flawless, diamond, as in a 'good' investment. Or a 'good' diamond could be a family heirloom, worn by several generations of fabulous women.
With every diamond comes a certificate
A rough diamond is typically identified by its shape, surface texture, and luster. It may appear as a rough, uncut stone with a glassy surface and a crystalline structure. Gemologists can also use specialized equipment like a loupe or magnifying glass to examine the diamond's characteristics further.
A genuine diamond can be natural or lab-created. A certified gemologist can help you identify the source of your diamond, and whether the diamond is indeed a diamond.
In the field, you can identify a raw stone because of its clarity and its extreme hardness.
A green diamond is a diamond in possession of a shade of green. A gemologist can help you identify the source of its colour -- whether natural or treated.
No, a diamond marking pencil is typically used to mark or draw on materials. To identify a diamond, gemologists use tools like loupes, microscopes, and other testing equipment to examine the stone's characteristics like color, cut, clarity, and carat weight.
Yes, a 10 carat diamond is 'good'.
Colored diamonds are often irradiated to enhance or change their color. Irradiation bombardment can alter the diamond's crystal lattice, causing it to absorb more light and appear differently colored. This process is a common method for producing fancy colored diamonds, such as blues, greens, and yellows.

The field test for diamond is extreme hardness. Other tests include the use of a probe, which jewelers use to identify diamonds.
You can identify a diamond ring on silver by examining the markings inside the band which should indicate the metal content (e.g. "925" for sterling silver) and the presence of diamonds. To verify if the diamonds are real, you can conduct a few tests at home such as the fog test (breathe on the diamond and see if the fog disperses quickly), the water test (drop the diamond into water to check if it sinks), and the reflection test (look at how light reflects off the diamond).
To identify a real diamond, you can perform a few tests. Look for imperfections or inclusions within the stone with a magnifying glass, real diamonds often have tiny imperfections. Conduct a fog test by breathing on the diamond - if it stays fogged for a few seconds, it may be real. Additionally, a professional jeweler can perform tests like using a diamond tester to confirm its authenticity.
