If you're in the market for a diamond, chances are you've heard about lab-grown diamonds. With their eco-friendliness, affordability, and ethical production methods, lab diamonds have become a popular choice for engagement rings and other jewelry. But as with any new technology, there are bound to be questions. Here are the most frequently asked questions on Reddit's r/labdiamonds, along with their answers.
What is strain in a diamond?
Strain refers to the internal pressure within a diamond that can cause it to crack or break. It can be caused by a number of factors, including heat, pressure, and radiation. Strain can also be caused by the growth process of a diamond, especially if it was grown quickly or under less-than-ideal conditions. Strain can affect a diamond's appearance, so it's important to buy from a reputable dealer who can guarantee the quality of the stone.
What is color tinge in a diamond?
Color tinge refers to the presence of color in a diamond that is not reflected in the grading report. For example, a diamond may be graded as an E color, but still have a yellowish tint when viewed under certain lighting conditions. Color tinge is often a matter of personal preference, but it can affect a diamond's value.
What are the ideal proportions of a round brilliant cut diamond?
The ideal proportions of a round brilliant cut diamond are as follows:
Table percentage: 53-57%
Depth percentage: 59-62.3%
Crown angle: 33.7-35.8 degrees
Pavilion angle: 40.6-41.0 degrees
These proportions are designed to maximize the diamond's brilliance, fire, and sparkle. However, it's important to remember that the proportions of a diamond are just one factor in determining its beauty and value.
Why do some lab diamonds test as moissanite on pen testers?
Lab-grown diamonds are made of carbon, just like natural diamonds. However, they can have different impurities and growth patterns that can affect their response to certain tests. For example, some lab diamonds can test positive for moissanite on pen testers because they have a similar thermal conductivity. This does not mean that the diamond is actually moissanite – it's just a quirk of the testing method. To avoid confusion, it's important to buy lab-grown diamonds from a reputable dealer who can provide certification from a recognized laboratory.
In conclusion, lab-grown diamonds offer a great alternative to natural diamonds, but it's important to do your research and buy from a reputable dealer to ensure you get the best quality stone for your money.
