I have been visiting quite a few Private Jewellers who also practice keeping the loose diamonds in a fold paper like eclarity, Josi gems, Fairy's Inc and White Dwarf. This is seems like a typical way how they keep the diamond.
Sometimes i really feel so sorry seeing this kind of post. Like previosuly the post of "diamond falling out from the setting" and the recent one "buying hardwarezone user ID to post bad review about JannPaul". Whether it is true or not i believe we should be able to judge ourself.
We should always visit as many jewellers as possible to compare their service, quality and price before making any decision. Trust what we seen rather than just believe blindly. Who knows who is the one behind doing all this thing.
I was in contact with one of the partners of white dwarf today. So far so good. Sent me aset images and hna images and gia cert. Showed me the settings I like. We we see how it goes!
