All of our diamond listings include the actual image of the diamond. Save this image for your files. The inclusions in the diamond act like fingerprints. They can be used to identify a diamond. You can have your diamond certified by an independent lab such as GIA or EGL. They give you a report has serial number along with its color, carat weight, measured dimensions as well as other diamond details. You can have your diamond laser engraved. Laser engraving will etch a non-removable serial number, logo or phrase along its girdle. When you get your item back, look for your engraving. You will need to use a loupe to see the microscopic lettering.
"Certified diamonds" have been tested and graded by an independent gemological lab. These diamonds cost more due to the extra cost of having the diamond certified. Certi
fication also gives you the added an insurance of knowing that what you get has been inspected by an independent lab. "Non-certified diamonds" do not have this independent report and relies solely on the seller's' ability to grade diamonds.
We do not offer certified diamonds to keep our prices low from expensive cost of certification. We post actual images and video of our diamonds in our listing. All of our diamonds are graded by our diamond expert with his 30 years diamond grading experience according to GIA slandered.
We cannot send diamonds out to be certified. It takes a long time to have a diamond certified and these diamonds cost more due to the extra cost of having the diamond certified. Once you receive your diamond, you can send it to an inexpensive independent lab or local jeweler to be value appraised report for insurance purpose.
There are two interpretations to the term "fancy diamond." The most common use relates to cut or specific shape of the diamond. Fancy refers to any diamond cut other than round including: marquise, pear, oval, emerald, princess, radiant and heart shapes. The second fancy reference is to diamonds that have a prominent body color, such as canary yellow, brown or blue. Some diamond colors are much more rare and valuable than others. For example, diamonds are often found in shades of yellow and brown. But colors such as blue,
pink and light green are uncommon. Deep pink is particularly rare.
We use color enhancement method for treated fancy colored diamonds only and some of our white diamonds have clarity enhanced. We do not use any methods to raise the grades of white diamonds. Such as enhancing a “G” color diamond to “E”. Each listed diamond has clear explanation under “Treatment” at description part on the diamond listing page. Under “Treatment”, if you see “None” means that diamond is not enhanced any way.
What process do you use to color enhance and clarity enhance for your diamonds?
There are many methods of enhancing diamond colors. Some are to whiten white diamonds and others are to enhance the color with diamonds with not-so-good color. At AtoZDiamond we use color enhancement for treated fancy colored diamonds only. We do not use any methods to raise the grades of white diamonds. Such as enhancing a “G” color diamond to “E”. The different methods we use to enhance the color in our diamonds are HPHT, Irradiation, Heat and Surface Enhancement. All our items are clearly labeled as Enhanced on our item description.
HPHT is a process developed by General Electric in 1999 to color treat diamonds. This process puts over 60 kbar (nearly 1,000,000 psi) of pressure on the diamond at around 1400°C (2550°F). Diamonds treated with HPHT can transform into many colors including to pinks and blues. HPHT can also be used to create white diamonds, however AtoZDiamond will only use this process to create fancy colored diamonds. This treatment is permanent and will not be affected by cleaning or heat from setting repairs.
Irradiation treatment involves exposing the diamond to electromagnetic rays to relese electrons from their normal location to a more desirable location changing its color. Neutron bombardment and electron bombardment are the two main irradiation methods practiced today. Diamonds treated by irradiation produce many brilliant colors such as green, yellow, blue and reds. This color treatment is permanent and will not be affected during cleaning processes. However, blue or green enhanced colors could change to a yellowish color if high heat, 300°C (572°F) or more, is used during setting repairs.
Surface Enhanced diamonds are chemically treated to change the color of a diamond to Brilliant colors. This is done by coating the diamond surface with a metal halide. A similar technique used to coat some camera lenses that create the blue reflection. This method can produce vibrant pinks and cognac reds. Care should be taken with surface enhanced Diamonds. The coating can wear out during heavy cleaning, color fade by after long use or heat from setting repairs.
Heat Treatment or 'annealing' is done using a combination of chemicals (beryllium, borax, lead, tantalum) and heat to change the diamond's color. Heating or "cooking" the diamond is done at temperatures ranging from 450°C (842°F) to 1850°C (3362°F) for 2 to 12 hours or more. We only use this process to create our black opaque diamonds. To check if a diamond has been heat-treated, one way is to look for the presence of small fractures within the stone that appear around natural mineral inclusions. This treatment is permanent and will not be affected by cleaning or heat from setting repairs.
If you already purchased setting or for customize jewelry, always ask your jewelers which size in millimeter you need to buy diamond, not how big it is it in carat. How "big" a diamond is can mean many things. For your prong set mountings, it will fine you buy 0.05mm to 0.25mm bigger or smaller. But any other kind set or any fancy cut mounting needs exact millimeter size diamond.
