Color Diamond
Pink Diamonds
Purples and pinks are some of our most asked- for colors but they are the most difficult to achieve. When we color enhance a thousand carats of the blues, greens, yellows and oranges we only achieve perhaps 2-3 carats of pinks and purples. Very few diamonds have the latent ability to turn pink or purple when irradiated or enhanced using HPHT, and even then most of them come in the more purplish shades which are less desirable and worth less than pinks.
Pinks & Purples come in a range of shades having undertones of red, orange & brown. These undertones are not desirable and are at best avoided. The scarce availability of Rose Pinks makes them more expensive than the Purples.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Yellow Diamonds
Tirupati Plastomatics offers a wide selection of Fancy Yellow, Canary Yellow, Golden Yellow and Lemon Yellow Diamonds. Yellow diamonds can come with undertones of green, brown or orange. None of these are particularly desirable; our aim is to create a diamond of the purest yellow possible. In order to do this, we use both the irradiation and HPHT processes. Because the HPHT process is quite difficult to carry out, our HPHT yellow diamonds are on the more expensive side of our price range. Also, black inclusions can easily be seen in a yellow diamond thereby these inclusions should be avoided.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Green Diamonds
The green diamond family includes an infinite palette of nuances and consists of bright colors such as mint and lime, but also more subtle hues such as khaki and olive. Pure green diamonds are extremely rare and highly valued, ranging from light mint greens to vivid grass greens. Green diamonds are usually found with undertones of yellow or blue and too much of these undertones are not desirable. We manufacture all of our green diamonds to come with the perfect balance of greenish and yellowish undertones. Too much yellow undertones will create a yellow stone, but the perfect balance heightens the brightness of a green stone.
We carry green diamonds in Olive Green, Ice Green, Lemon Green and Apple Green shades and are available in Rounds, Princes’ cuts and various special shapes. Our green diamonds are priced at different quality levels, and are graded on the basis of color and clarity.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Cognac Diamonds
Cognac color enhanced diamonds are visibly similar to their natural counterpart making it very popular. Also, they go particularly well with rose gold, white gold and yellow gold. Our cognac diamonds come in two shades; Orangish Cognac and Reddish Cognac. Reddish Cognac is basically a more intense reddish shade of Orangish Cognac. Red & Orange diamonds can come with undertones of brown and black. None of these undertones are particularly desirable; our aim is to create a diamond of the purest color possible. A lot of diamonds become blackish when we are making the reddish cognac and this low yield makes the Reddish Cognacs more expensive than the Orangish Cognacs.
We carry Reddish Cognac and Orangish Cognac Diamonds in Rounds, varying from 0.002 ct to 10.00 cts. They are priced at different quality levels depending on clarity and brightness of color.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Blue Diamonds
All of our blue diamonds are irradiated using the completely safe low-energy electron acceleration process. Because the Ice Blues are created using the clearest diamonds they are the most expensive. Darker blues are made using darker shades of brown diamond making them a more affordable alternative. When it comes to choosing a blue diamond, you should beware of any greenish shades. Any underlying greenish tones reduce the value of a blue diamond. Feathers can be seen quite clearly in any blue diamond, so the higher the clarity the better. Our blue diamonds are priced at different quality levels, and are graded on the basis of color and clarity.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)

Non-Certified Diamonds
Many diamonds are not certified for a variety of reasons. Certification costs, and some merchants don’t want to incur additional expenses. Sometimes, jewelers think it’s not worth it to have low-quality diamonds certified because for such stones, a certificate would not make a big difference to the buyer.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Certified Diamond
Certified diamonds are stones that have been formally appraised and whose quality characteristics have been documented. Such diamonds come with a grading report, which is the document describing their clarity, cut, color, carat weight, and other important features. Anand International offers certified round brilliant diamonds in clarities ranging from IF to SI2 and sizes 0.30 carats to 2 carats and above.Login To Buy Now
Brown Diamonds
Brown colored natural diamonds have their own aesthetic appeal and grown numbers of consumers are attracted by the appeal of something unusual which retains the diamond mystique. We believe we have significantly contributed to driving consumer demand in this range of diamonds across the world by reliably creating standardized assortments which have given jewellery manufacturers the confidence to be creative and ambitious in their development of appealing collections. We played a major role in dispelling the previously held perception that brown diamonds were inferior and encouraging the feeling that they are complementary and a valuable extension to jewellery manufacturer’s collection and the diamond dream. Anand International offer C1 to C7 range in brown diamonds, when grading these diamonds, the trade uses the C1 to C7 grading scale. This scale separates the tone or depth of color progressively. On one end of the scale, C1 denotes the Champagne color and on the other end, C7 describes the Cognac color.
FULL CUT SIZE: 0.002 CTS (0.7 MM) TO 10.00 CTS (14MM) SINGLE CUT SIZE: 0.002 CTS (0.7 MM) TO 0.01 CTS (1.3MM)
Black Diamond
Black diamonds have the same chemical structure as white ones and are therefore real diamonds. Inspite their relative cheapness, black diamond’s remain incredibly popular. Almost any diamond can be turned in to black by using of the heated process. Black diamonds are the easiest colored diamonds to buy as they do not come in different shades. The main clarity characteristics of Black Diamonds are broken girdles or open cavities on the surface. It is the presence or absence of these surface inclusions that help you determine the price.
We also carry Pears, Marquises, Ovals, Radiants, Cushions & Emerald. We carry different qualities graded based on the presence or absence of surface inclusions.

What is Irradiation process? (E-BeamTechnology)
Irradiation is the process where the fire a pulsed beam of electrons at the diamond , which then disturbs the electron of the diamond itself, causing them to be knocked and captured by other atoms the light absorbing structure of the gem is changed and as a result is their "color".
we use only low energy electone method of irradition which is the safest way to irradiate diamonds.
Irradiated diamonds are genuine natural diamonds that exhibit an intense color change such as blue, cognac, green, yellow or pink.
HPHT Process?
High Pressure High Temperature (HPHT) process to enhance diamonds, performed only on the highest quality natural diamonds with no inclusions and high clarity grades on those diamonds are high quality and have a special chemistry that allows for color change.
the process allow the natural trace elements within a diamond to relax and to display their natural color .by using highly advanced HPHT machine expose the diamonds to heightened heat and pressure resulting in the change of color of the diamond.
Color
A diamond's color grade actually refers to the absence of color. In other words, diamonds that are white, containing little or no color, receive higher quality grades than those with noticeable color.
A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value.
A color scale established by the Gemological Institute of America (GIA) assigns a letter to the degree of colorlessness found in a diamond. Beginning with D and ending with Z, each descending letter denotes an increasing amount of light yellow, brown or gray in the diamonds.
Color of the polished diamonds starts from Colorless D-F), near colorless (G-J), faint color (K-M), very light color (N-R), light color (S-Z) to fancy color (Z+). In diamond trade terminology is referred in alphabet starts from D to Z.
Clarity
A diamond’s clarity is measured by the existence, or absence, of visible flaws. Tiny surface blemishes or internal inclusions — even those seen only under magnification with a jeweler’s loupe — can alter the brilliance of the diamond and, thus, effect its value.
FL, IF:Flawless, Internally Flawless. There are no inclusions — internal flaws — or blemishes — external flaws.
VVS1, VVS2: Very, Very Slight Inclusions. Hard to view such inclusions under 10x magnification. An excellent quality diamond.
SI1, SI2: Slight Inclusions. Inclusions are visible under 10x magnification and may not be visible to the naked eye when the stone is in the face-up position.
I1, I2, I3: Included: Inclusions are obvious under 10x magnification and may affect transparency and brilliance. I1 diamonds have inclusions that are almost always visible to the naked eye.
Carat
Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams. Each carat can be subdivided into 100 'points.' This allows very precise measurements to the hundredth decimal place.
Carat reflects the weight of the stone, which includes depth, height and diameter of the stones. Prior to the twentieth century, diamonds were measured using carob seeds, which were small and uniform and served as a perfect counter weight to the diamond. The word "carob” is the origin of the word "carat" that we use today.
One carat is the equivalent of 0.2 grams One carat is also divided into 100 points. Points are generally used to describe increments of weight within a carat. The weight of a 3/4-carat diamond can be shown as .75 carats or 75 points.
Cut/Polish/Symmetry
A diamond's CUT not only refers to its shape, but also how effectively the stone can return light back to the viewer's eye. A well-cut diamond will appear very brilliant and fiery, while a poorly cut stone can appear dark and lifeless. CUT verification can be done through comparison of parameters of facets. A well cut diamond will be symmetrically round, proper depth and width, and have uniformity of the facets.
A diamond cutter will follow precise mathematical proportions relating to the height, width and depth of the crown (top), girdle (widest part) and pavilion (bottom). When a diamond is cut to the right proportions, light reflects from one facet to another and then disperses through the top of the stone, resulting in a burst of fire and brilliance. Fire is the flashes of color one sees when you look at a diamond; brilliance is its sparkle.
Polish is the overall condition of the surfaces of a finished diamond. Polish is rated Good (GD), Very Good (VG), Excellent (EX), and Ideal (ID).
Symmetry refers to the precision of the shape and arrangement of facets in a diamond. Although to the naked eye finish features only have a tiny effect on appearance, symmetry is an significant aspect.
