When people shop for engagement rings, color is one of the 4Cs that is most misunderstood. This is due to a lack of experience and ability to compare diamonds in a fair and neutral manner. It doesn't help that sales people want to upsell more expensive rings so that they can make a bigger commission off your purchase. As a result of this, there is an incentive for them to push for higher color grades and to spread misinformation.

In this video, we compare a F, H and K color diamond ring in a side by side manner. This enables you to look, analyze and come to your own conclusion away from a pressurized environment. Are F diamonds good enough? Are H or K diamonds too yellow? What grade of color do you need for them to look white to the eyes?

Watch this video in full length and leave a comment below to share your thoughts. Given that there is a huge price difference between these color grades, would you be willing to pay more for an F colorless diamond or will you be alright with lower H or K colors?

$Diamond Ring Testing - How to Tell If a Diamond is Real For a complete write up on how to correctly identify a diamond, go to https://beyond4cs.com/faq/how-to-spot-a-fake-diamond/ In this video, I purchased a cheap diamond tester online from eBay and used in on an existing real diamond ring that I had purchased for my wife. The diamond tester works on the principle of thermal conductivity (because diamonds are SUPERB conductors of heat due to their compact covalent structure). The diamond tester has a light meter which lights up depending on how much heat is transmitted away from the tip after it gets into contact with the surface of the diamond. Do take note that the diamond tester has to be used properly and angled properly to the diamond for a proper contact or you will get misleading results from the test. If a real diamond is detected, the light bar lights up to the DIA level to indicate a real diamond and a beeping sound will be heard from the equipment. In order to differentiate between a real vs fake diamond, this affordable tester can to correctly identify real stones vs fake gemstones with the exception of a few gemstones like moissanite. For the case of moissanite, you will need to use a diamond tester that has an electrical conductivity test or manually use a 10X loupe and check the gemstone for refractive doubling. Higher end diamond testers like those from the Presidium brand will have such functions in place to differentiate between a real diamond and a fake diamond like moissanite. https://beyond4cs.com/go/amazon-presidium/ If you want a simple diamond tester and have the physical knowledge to use a 10X loupe to identify a moissanite, you can use the testers here in conjunction with that knowledge: https://beyond4cs.com/go/amazon-diamond-tester/ https://beyond4cs.com/go/ebay-diamond-tester/ For a more professional level of testing to differentiate between diamonds and common gemstones, I recommend the Presidium gemstone tester: Ive also written a couple of other comprehensive guides to help you identify a diamond from other common simulants found in the marketplace. Check them out in the links below: https://beyond4cs.com/faq/how-to-spot-a-fake-diamond/identify-a-moissanite/ https://beyond4cs.com/faq/cubic-zirconia-vs-diamond/ As always, the best way to ensure you are getting what you paid for when buying a diamond ring is to shop at a reliable place and buy a diamond with a GIA or AGS certificate.$
