Synthetic Blue Diamonds

Synthetic Blue Diamonds

New Synthetic Blue Diamonds are now on the market. The synthetic blue diamonds were on display at the Hong Kong and Bangkok jewelry fairs in September 2013. Orion PDC Diamonds manufacture these new synthetic blue diamonds. They specialize in producing synthetic colored diamonds. The company can only produce synthetic blue diamonds in small quantities. Only from 0.25 carats in diamond weight to 1.25.

Synthetic Blue Diamonds and CVD

The products development came after extensive testing by GemResearch Swisslab by using a technique known as chemical vapor deposition (CVD). These chemical vapor deposition-grown blue diamonds are inert to both short wave and long wave ultraviolet light. Their illumination reveals no particular phosphorescence characteristics of high pressure-high temperature (HPHT) or natural blue diamonds. This new generation of synthetic blue diamonds can yield diamonds with claritys from Very Slight 2 (VS2) to Very Very Slight 2 (VVS2). Furthermore, they are impossible to differentiate between its natural diamond counterparts using a loupe, microscope or a diamond tester according to the manufacturer.

Synthetic Blue Diamonds and Illumination

These CVD-grown synthetic blue diamonds are inert to SWUV and LWUV light. Moreover, they reveal no particular phosphorescence characteristic of HPHT-grown or natural blue diamonds. Furthermore, they come only in higher clarity spectrum. Furthermore, it is almost impossible to discern these items from similar color natural diamonds. Optical spectroscopy (UV-VIS, FTIR and PL) displays them as a type IIa diamond. The color the show is because of strong absorption of very silicon-related inside. In contrast, the natural and HPHT-grown synthetic blue diamonds emit a color due to of boron impurities. The silicon blue CVD diamonds are not electrically conductive either. Thus, an electrical conductance test is a further indicator of the CVD origin of these diamonds. This test method is also useful to help identify irradiated blue natural diamonds. All of which are of type Ia or IIa, since they act as electric insulators.

Synthetic Blue Diamonds VS Natural Diamonds

Natural blue diamonds are the most expensive and rarest diamonds in the world. Moreover, they stand next to natural pink diamonds as the most expensive colors on the market. Almost every color of a natural diamond is available in a synthetic version. Furthermore, today, a vast number of industrial labs produce diamonds. This is particularly the case in Asia. This in part due to market and lower production costs. CVD technology seems to be an increasingly popular technique to grow both near-colorless and colored diamonds. This new method makes it imperative for consumers to observe melee and smaller color diamond parcels diligently. http://www.diamonds.net/News/NewsItem.aspx?ArticleID=45256&ArticleTitle=New+Generation+of+Synthetic+Blue+Diamonds+Reach+the+Market https://www.miadonna.com/pages/stone-guide-lab-created-diamonds
