    5 Carat Diamond Just how rare is a 5 carat diamond of gem quality?  It’s really hard to say.  Most mine estimates indicate that on average 250 tons of potentially diamond bearing rock must be processed in order to yield a diamond of one carat.  And only about 20 percent of diamonds found are of gem quality.  The rest have only value for the abrasives industry.    Approximately half the weight of the original rough diamond is lost in the cutting process- significantly more, if the diamon... read more

    Is EGL certification as good as AGS or GIA? From a standpoint of accuracy and consistency, the consensus of the experts is that EGL certification is not as reliable as diamond certification done by AGS or GIA. As a result, diamonds marketed with EGL reports are significantly discounted relative to diamonds with reports from AGS Laboratories (AGSL) and GIA.   Diamond certification is part science and part practiced skill, but it is also a business.

  • 9/7/2012  Princess Diamond - Why are there so few Ideal Princess diamonds on the market?

    Why are there so few Ideal Cut Princess Diamonds on the market? The short answer is because GIA has elected not to put an overall cut grade on princess cut diamonds, as they do for rounds. While GIA reports on princess cuts (modified square brilliant) do contain aspects of cutting- polish and symmetry- this does not begin to tell the story of light performance. In terms of fire, brilliance and sparkle, there is a huge difference between mediocre princess cuts and ideal cut princess diamonds.   The result is a ma... read more

  • Diamond Carat Weight

    Diamond Carat Weight Not to be confused with “carrots”, the crunchy orange vegetables that Bugs Bunny loves to eat, a “carat” refers to the weight of a diamond. As Mae West put it; “I never worry about diets, the only carrots that interest me are the number of carats in a diamond.” Diamond carat weight is only one of the commonly known “4-C’s” (clarity, color, cut, carat) of diamonds, but it is probably the one people are the most familiar with. It is the sim... read more

        Actually, some older systems did start with A.  Like chicken eggs, there were even grade AA and AAA diamonds.      In the 1920s, before the Gemological Institute of America (GIA) introduced its D-Z system, color descriptions for diamonds had been developed for purposes of sales, not science.  Vague adjectives like canary yellow, white or blue-white were used.  Diamond dealers were using 1, 2, 3 or I, II, III as well as A, B, C in their grading scales, and... read more
  • Whiteflash A CUT ABOVE® and Expert Selection: What's the Difference?

    "It’s All In The Hearts" This has been Whiteflash's assertion since becoming involved in the Hearts & Arrows diamond movement in the 1990s.  Their strong convictions have resulted in his ascension to a position of foremost authority on this elite aspect of diamond cutting.         The hearts are the life of light performance in a Hearts and Arrows diamond.  The pavilion mains are the engines that drive all light return, and the lower girdle facets guide reflec... read more
  • 8/2/2006  Should World's Gem Labs Shun Synthetic Diamonds?

    A diamond grading report from a recognized gem lab is not just a pedigree but a passport. As more consumers have become aware of certificates, they have insisted on them as objective third-party opinions about the nature and quality of stones they are buying. Sale of stones is often dependent on these documents. No paper, no sale. Given the importance of certificates to the buying public, De Beers and the world's leading diamond trade organizations have tried to get major labs to refrain from issuing them for synthetic (m... read more
  • 8/2/2006  Have Hearts & Arrows Diamonds Gone Square?

    Super ideal cuts are no longer just round. One of the hippest new cuts of the last decade has gone square. Thanks to the galloping popularity of the Princess Cut (a square), at least three major companies have introduced hearts and arrows square cuts—branded, respectively, as the "Dream Cut," "Regent Cut," and the "Hope." More are on the way. Here's why. Super ideal cuts possess what is called "optical symmetry." That means that these stones make perfectly matched sets of he... read more
  • Colored Diamonds Are Hot for Fall!

      Because of price and rarity, colored diamonds have always been an elite product. Suddenly, however, they are going mainstream, appearing in hundreds of independent jewelry stores as a new means of differentiation from their discount and chain competition. Several factors are contributing to the trend.   First: Indian and Israeli diamond cutters are producing many small yellow, pink and brown diamonds suitable for use in pave, cluster and other multiple-stone settings that use melee. Jewellry manufacturers ar... read more
  • 8/2/2006  AGS To Begin Grading Princess Cuts

    The American Gem Society, which has been grading round brilliants for cutting since 1996, will begin to grade fancy cuts in 2005. The first shape for which it will offer what it calls cut quality analysis is the highly popular princess cut, a square shape introduced in 1981 as an alternative to the radiant rectangle cut. As it does with round brilliants, AGS will divide its princess cut grade into three parts: light performance, proportion factors and finish—each with a high rating of Zero and a low rating of 10. H... read more
  • 8/2/2006  Are Irradiated Diamonds Safe to Wear?

    In 1942, scientists at the University of Michigan put some diamonds in a cyclotron and zapped them with heavy radiation to produce vivid green stones.   After a brief quarantine period during which residual radioactivity disappeared, the world had its first artificially colored diamonds that were safe to wear.   These diamonds were purely experimental. Commercial stones colored by irradiation weren't introduced in large numbers until the 1950s. And when they were, the market for naturally colored diamonds crash... read more
  • Why don’t you use the Brilliancescope?

    GemEx, manufacturer of the Brilliancescope, admits a built in error of +/-5%, making comparisons of diamonds impossible except on a broad scale. This device was developed for sales, not science, and has no endorsements from laboratories or scientific bodies. The GIA and AGS have tested and rejected this device.... read more
  • Why are ASET, Ideal-scope and Hearts & Arrows images more meaningful?

      ASET, ideal-scope and H&A images are proven natural methods of interpreting the performance potential of a diamond with static, natural views. Hardware issues, calibrations and software calculation errors inhibit mechanical interpretation of diamond beauty. Natural views with these simple and elegant tools have no such error.... read more
  • Why do you use GIA and AGS labs for grading?

      The Gemological Institute of America and the American Gemological Society were both founded by Robert Shipley in the 1930s. GIA’s Gem Trade Laboratory has been grading diamonds since 1939. These organizations are acknowledged as the most reputable diamond grading laboratories in the world. An official GIA or AGS document increases the value of a diamond. As of 2006 both of these labs are assigning cut grades for round brilliant diamonds. The AGS offers a grade for princess cuts as well.   The AGS began... read more
  • A CUT ABOVE®: About Hearts & Arrows

    A CUT ABOVE®  : About Hearts & Arrows   A CUT ABOVE® Hearts and Arrows Super Ideal In the 1980s Japanese cutters were the first to produce diamonds cut so exactly that facet reflections overlapped, creating kaleidoscopic patterns when seen through reflecting viewers. The techniques spread to other cutting houses and evolved. Hearts & Arrows (H&A) diamonds reached... read more
  • Which HCA score is better, 0.1 or 1.9?

    Neither. They are equal indicators of predicted beauty. This is a common misconception, explained in small print on the HCA results page: “A score below 2 (Excellent) means you have eliminated known poor performers (more than 95% of all diamonds). Your own personal preference may be for a diamond with an HCA score of 1.5 more rather than one with a lower score of say 0.5.”... read more
  • What are Expert Selection diamonds?

      The Whiteflash Expert Selection category contains certified diamonds of outstanding quality. As the name implies these diamonds are selected by our experts for superior light performance and beauty. In order to be considered for Expert Selection a round brilliant diamond must have been certified as AGS Triple Ideal (Triple Zero) or by GIA as Triple Excellent, the highest grades for cut quality by the two foremost laboratories in the industry. In addition, Expert Selection Round diamonds must exh... read more
  • What are Imagem, Brilliancescope and Isee?

    These machines have been developed to measure a diamond’s light output. Imagem and Brilliancescope are among the most well-known. These devices provide interesting information that may be considered a useful part of the big picture, but they have met resistance from major laboratories and the science community. For this reason they take a backseat to natural reflector assessment.... read more
  • What are Sarin, Ogi and Helium reports?

      These are all devices used by respected gemological laboratories, vendors and appraisers to arrive at precise measurements for all diamond proportions. Some grading reports do not provide every angle and measure but a Sarin report does. At Whiteflash we feel your investment is worth having such a machine onsite so that we can provide this information for you. If a diamond has a GIA report prior to 2006 you can click on its Sarin report to get measurements not included on the GIA document. AGS documents have most of... read more
  • What are your policies for setting diamonds and related charges?

    If a customer buys the diamond and setting from Whiteflash no additional setting charges apply. If a customer buys a diamond from Whiteflash and sends in a setting purchased elsewhere there is a setting charge, providing the setting is of an acceptable standard. If adjustments need to be made to the setting to accommodate the diamond additional charges will apply. If a customer buys a ready-made setting from Whiteflash we ship the setting but will not set a diamond purchased... read more
  • What is more meaningful - HCA numbers or an Ideal-scope/ASET image?

    No computer projection is as meaningful as actual assessment of the 'live' test subject, so the Ideal-scope image is more telling. If we think of a diamond as a container of visual potential, PROPORTIONS numbers merely describe the outside of the container, while PERFORMANCE assessment evaluates the actual contents of the container.... read more
  • Diamond Photos: Why Are There Dark Arrows?

    The bottom-most facets on the diamond (the main pavilion facets) draw their light from the highest angles.  When a Hearts & Arrows diamond is photographed from directly overhead, these areas will go dark if the camera blocks, or obstructs, the light source.  This is known as obstruction.  The dark areas are, literally, a reflection of the viewer or camera lens in the crown of the diamond.       Will I see dark arrows in real life?    Not unless you work hard to... read more
  • 7/25/2006  Diamonds: The Evolution of the Round Brilliant Diamond

    1650: Cardinal Mazarin designed the first cross-cut diamond, which was the beginning of the brilliant style of cutting. In the early 1700s the Portuguese diamond cutter Peruzzi refined the first 58 facet brilliant cut. This style slowly evolved throughout the 1800s, known first as the old-mine cut and later as the old-European cut. These cuts still followed the contours of the rough diamond in order to retain as much weight as possible. 1860: Henry Morse opens a diamond cutting firm in Boston. By 1880 he is recutting trad... read more
  • Grading Lab Reports Are Not Created Equal

    Diamonds are sent to different grading labs to serve a purpose.  Diamond cutters and sellers want to maximize their profits, so they choose their labs strategically.  In the mainstream that decision is not necessarily being made with the objective of providing buyers with the most accurate shopping information. Strictness, consistency and information vary between diamond grading labs.  The lab’s client was the manufacturer or seller and the reason they bought that lab’s report was to help them s... read more
