"BGM" EXPLAINED

AND WHY TO AVOID IT

You probably know a fair amount about the 4 C’s: carat, cut, colour and clarity are the main things to look out for. But there’s something else you need to check in order to ensure that your diamond does not have an unwelcome colour tone.

BGM stands for Brown, Green, and Milky. It means that sometimes a diamond can have a brown-green undertone or a milky opaqueness.

Milky and slightly opaque

BGM is something not indicated on a diamond grading report. But if you see it in person, you could notice a milkiness that dulls the sparkle, or dark hues that will detract from the majesty of it's appearance and reduce it's worth considerably.

Therefore it is crucial to work with a trusted expert like Pobjoy Diamonds before purchasing your diamond.

That's because even a diamond with impressive grading in terms of the 4 C’s can still have these undertones. It may be everything you wanted on paper but disappointing when seen in person.
