Bidz.com and independent Gemological laboratories Bidz auction Sold fake diamonds from Bidz los angeles, New york New York

I feel sorry for the consumer who was taken. The comment that diamond and moisenite are too close to tell the difference is absurd. If you are a genuine gemological laboratory the refractive index and Specific gravities are simple enough to determine. They should know better. Shame on them. I'd fire the tech.

Now that that is out of the way. Diamonds are niether rare nore valuable. Untill 1946 MOST diamonds were ground up for industrial applications.(truth)

It wasn't untill the De Beers camapian "Diamonds are forever" They guilted fiances into paying exuberant prices for a common stone. De beers owned 90% of globl diamond market. with new technology and practices diamond sales were slumping.(This taken directly from their 1946 business modle) Due to the earths plate techtonic Vulcanism diamonds are produced by the metric tons annually. it's why when you try to sell your diamonds nobody wants them or pays you scrap weight for the gold platinum.

I do not sell gemstones. I set them. I have no dog in the ring. You are Fare better off buying rubies sapphires Bixbite Benitoite hyaune or any other host of VERY RARE gemstones that are due to be mined out very soon for 1/2 of diamond prices. Zircon is actualy a better stone. It's doubly refractive nearly as hard. You can  buy a specialty cut for 1/3 the price of diamonds. ( Not CZ. DeBeers had something to do with the naming of Cubic "Ziconia" On purpose) It's why when you take Grandpas old Emerald or Grannies old Ruby dealers foam at the mouth. Don't buy diamonds unless you can afford investment grade and a dealer to sell them for you.

I have had three certificates of authenticity throw indpendent gemological laboratories Los Angeles. I have had other Jewellers look at the pieces and even do a few tests and they all seemed to add up except one which concerned me. One item weighed in grams more then the COA stated which was a big mistake. I asked the jewellery what that could mean and they said it was likely the scales weren't synced properly or something like that can't remember the exact words. Though they told me it didn't really mean anything the mistake was big and still concerns me.

However I won't straight away claim they are frauds over moissanite. Moissanite itself is uncommon however cheaper then diamonds yet is the only other gem than diamonds that will pass a diamond test. It is common for experts to confuse moissanite as diamond that's how similar they are. It's a common mistake in the gem world so once again I won't be claiming fraud over a common mistake. However if it was me I would get the COA that claimed moissanite and try to talk to bidz as you were not sold what they claimed they were selling and you would have proof of it.

I know one way to tell the difference between the two is that the girdle of a diamond is facetted while the girdle on a moissanite is smooth. It's better to tell with a jewellers magnifier.

Better luck in the future.
