Jennifer Aniston appeared on the red carpet in $10.7 Million Worth of Diamonds custom designed by Lorraine Schwartz

This year Oscars Red Carpet shined and dazzled even more than last year as A-list stars appeared with stunningly beautiful diamonds. Jennifer Aniston reached even the diamond price of $10.7 million dollar worth of diamonds by herself. Bold and big statement necklaces were dominating the carpet as for example Karlie Kloss arrived with a flowery white golden choker set with 38-carat of diamonds.
Besides the statement necklaces diamond earrings were popular accessories of the celebrities, from climbers to big diamond drops that had layers of gem pieces. Surprisingly the carpet was filled with colorless diamonds more than colored diamonds this time. But when colored diamond appeared on the red carpet it was far more than beautiful.

De Beers Unveils New Synthetics Detector

De Beers showcased an updated version of its automated melee screening machine, the AMS2, in Hong Kong on Wednesday, claiming it could check a wider range of diamonds for undisclosed synthetics, and at a faster rate.

The new version was brought to market in response to customer requests, particularly since there has been an increase in cases of undisclosed synthetic diamonds mixed in parcels of natural diamonds, explained Jamie Clark, commercial director of the International Institute of Diamond Grading & Research (IIDGR) – the De Beers subsidiary that developed the machine.

“Confidence is everything in the diamond sector, and the AMS2 will play a big part in maintaining trust in trade transactions,” added IIDGR president Jonathan Kendall during the unveiling at the Hong Kong Diamond, Gem & Pearl show.

The AMS2 allows screening of stones as small as 0.003 carats, whereas the first-generation machine started with 0.01-carat diamonds. That’s crucial to the watch industry in particular, which works with diamonds smaller than 0.10 carats, Kendall explained.

AMS2 also checks all shapes and cuts, starting from 0.01 carats for fancy shapes.

According to Kendall, the updated machine is 10 times faster than its predecessor, can check up to 3,600 stones per hour, and refers fewer goods for further testing.

Weighing 227 carats, latest gemstone from Lucapa’s Angolan diamond mine

Big, valuable gemstones that may eventually get cut into smaller diamonds keep getting discovered in Angola.

Today Lucapa Diamond Company Ltd. (ASX:LOM) said it has uncovered yet another epic rock from its Lulo mine, the second largest to be pulled from deep inside the earth at Lulo.

The stone weighing 227 carats, discovered by Lucapa and its partners, Empresa Nacional de Diamantes EP, and Rosas & Petales, is a Type IIa D-Colour gem. It’s the same type of diamond that Lucapa recovered in September, in that case weighing 172.6 carats. The largest diamond to come out of the mine was a 404.2-carat monster that Lucapa unveiled a year ago, and which Lucapa later sold for AUD$22.5 million. The huge rock bested Angola’s previous record for its largest diamond, the Angolan Star, a 217.4-carat gem recovered in 2007.

GEM QUALITY CVD DIAMONDS


CVD DIAMOND MANUFACTURING PROCESS

Gem Quality CVD Grown Synthetic Diamonds

(I Colour 3.23 Carat and H Colour 2.52 Carat Round Brilliant Cut CVD Diamonds)

Gem Quality CVD DiamondsGem Quality CVD Diamonds: Grown by chemical vapour deposition (CVD) Synthetic CVD diamonds, have rapidly improved in recent years due to advances in growth techniques and post growth decolourising treatments. Near-colourless CVD synthetics have now passed the three-carat threshold. HRD Antwerp, September 2015, received a 3.09 ct sample (I colour, VS2 clarity). Pure Grown Diamonds announced earlier that they had successfully grown a 3.04 ct synthetic (I colour, SI1 clarity)  Dec 2014.

GIA LABS ON CVD DIAMONDS

GIA’s New York laboratory recently tested two large CVD synthetic diamonds submitted for grading services.  The largest CVD-grown diamonds GIA has examined to date are these two synthetics. The results of the examination underscore the continued improvements in CVD synthetic diamonds.

The 2.51 and 3.23 ct round brilliants received H and I colour grades, respectively. Identified in each stone were pinpoints, and black inclusions.  Observed in the 2.51 ct round were some small fractures along the girdle. The 3.23 ct synthetic contained a small black inclusion measuring approximately 125 µm. Therefore the 2.51 and 3.23 ct were given clarity grades of SI1 and VS2. Irregular stress patterns with high-order interference colours when viewed under cross-polarised light , indicated high levels of internal strain.

High quality CVD synthetic diamonds are , without post-growth decolourising HPHT treatments by the analysis, done by both HRD and GIA, marking a significant improvement in CVD growth.  Using advanced spectroscopic and fluorescence imaging technologies, it is nevertheless possible to detect low concentrations of impurity centers, allowing conclusive determination of these samples’ synthetic origin. GIA is monitoring the development of laboratory-grown diamonds and conducting research to ensure that we can continue identifying every single synthetic diamond.

GEM QUALITY CVD DIAMONDS LAB IDENTIFICATION

The synthetics showed weak orange fluorescence to conventional short-wave UV and were inert to long-wave UV radiation. Exposure to the deep UV radiation ( 230 nm) of the DiamondView revealed an overall strong red-pink fluorescence, which was attributed to nitrogen-vacancy centers with dislocation bundles that fluoresced violet-blue, followed by weak greenish blue phosphorescence.

Grown using a multi-step technique and the crystals had a layered structure, thus maximizing production volumes. Sharp boundaries between different growth layers are a result of changes in the fluorescent impurity uptake during the start, stop phases, produced by applying at least five layers. Dislocation bundles propagated throughout the material. We don’t understand the two blue bands of highly concentrated dislocations crossing the table of the 2.51 ct.

CVD DIAMONDS


Fully Grown CVD Diamonds

CVD DIAMONDS – SYNTHETIC MAN MADE

Produced using microwaves and gasses in vacuum plasma reactors CVD Diamonds “Chemical Vapour Deposition” are synthetic diamonds. Due to a heated exchange hydrocarbon gasses break down, and carbon atoms begin to precipitate in thin layers onto a flat substrate or wafer. The deposits occur a in similar way that layers of ice or snow may build up whilst freezing.CVD DIAMOND MANUFACTURING PROCESSEffective substrates include diamond, silicon, tungsten, molybdenum, silicon carbide, silicon nitride, quartz glass or cemented carbide. Growth rates of around 0.10 millimetres (mm), or 100 microns of diamond hour are commonplace. While growth has its limits in terms of depth, CVD stones over 3 mm in thickness are very difficult and expensive to grow.

(Image: a microwave plasma reactor for producing CVD diamond).

CVD DIAMOND PLASMA REACTOR

 

Initially the  process was successfully developed by Houston, Texas based chemical manufacturer Union Carbide Corporation in the 1950s, the CVD process is less costly and simpler than the HPHT process. Hence the equipment is less expensive, and  the process is conducted a moderate temperatures and lower pressures.

Like HPHT, the CVD method has recently become economically viable. CVD synthesis capability has advanced noticeably in recent years. Especially relevant is the emergence of several startup companies attempting to commercialise the production of CVD gem quality synthetics.

CHARACTERISTICS OF CVD DIAMONDS

(Image: CVD diamonds )

Due to tFully Grown CVD Diamondshe unique growth processes, CVD stones are similar to type IIa rough, contain minimal amounts of nitrogen, have a high thermal conductivity. Consequently CVD diamond has unique shape, the CVD method, produces flat, tabular synthetic diamond crystals, which are different to natural diamond crystals in structure. As a result it has been extremely difficult to grow CVD stones deeper than 3 mm, most CVD diamonds are smaller than 1 carat.

USES FOR CVD DIAMONDS.

  • Optical uses (e.g. infrared windows, lenses, ATR units, X-ray windows)
  • Thermal uses (heatspreaders, laser submounts, X-ray targets)
  • Mechanical uses (cutting tools, scalpels, knives, length gauge tips, wear resistant components e.g. for textile machines, insert for dresser tools)
  • Electrochemical uses (electrodes, electro-chemical detectors, bio-chemical sensors)
  • Radiation sensors (ionizing radiation detectors/dosimeters, fluorescence beam monitors)
