- Blue-white diamonds. Some jewelers use the this term to describe diamonds with blue fluorescence. However, in daylight such diamonds might look milky or oily and are not so expensive.
- Bright light. Even the most "faint" diamond would look much better under bright light. That is why some jewelers use more strong bulbs to make their diamonds fluorescent blue.
- Grade exaggeration. There are jewelers who are not accurate in terms of color grade and clarity grade and used to exaggerate both of them to increase the price. For instance, you might be told the diamond is of F color and VS1 clarity whereas it is of G color and VS2 clarity. Such disagreement would cost you $1000 at a minimum.
- Laser drilling. "One third of all diamonds sold in jewelry stores are laser-drilled" a diamond expert Fred Cuellar claims. Jewelers use such a trick to get rid of black inclusions found in diamonds. Indeed, gems look more clear however more fragile.
- Coloring. Colored diamonds are more rare in nature thus more expensive. To raise the price for usual colorless gems jewelers "color" them by applying a tiny point of pink or green color on the diamond's lowest tip. This is enough to make it look colored and pricey.
- HPHT treatment. High pressure high temperature treatment is used for not sellable diamonds, usually of brown color. After applying high pressure and heat diamonds are reformed and improved. Thus, brown low-cost diamonds can be turned into fancy yellow or yellowish green expensive gems.
However, we are living in the time when diamonds can be affordable and real. Those are created diamonds. They are the same diamonds but cheaper. The only thing created diamonds differ from natural is the origin: laboratorial instead of geological. Natural diamonds are formed in volcanic rock deep under the surface while created are grown by man, the rest is the same: longevity, hardness, toughness and heat resistance. Grown diamonds possess the same rainbow effect and brightness and look identically to natural diamonds. Moreover, the most perfect thing is that they are certified by reputable gemological laboratories; that means while purchasing created diamond a customer could ask for a certificate where there is a detailed description of the gemstone.
There are several brands of created diamonds like Gemesis, Apollo, Chatham, New Age Diamonds, Adia Diamonds. It's rather easy to find retailers of each manufacture in the States. The greatest thing is that you won't be cheated and you won't have to overpay. Affordable price and real diamonds - the dreams come true today.
