CUT
The most important quality characteristic of a round brilliant diamond is the cut, which impacts the brilliance, fire and scintillation of the diamond. If the cut of a diamond is poor, the diamond will look dull and lifeless. When diamonds are certified by a gemological laboratory, they get a rating for their cut that ranges from Fair to Excellent. Melee diamonds are not certified by a lab due to their small size, but Dimexon’s own graders ensure that the cut of each stone is in line with the GIA’s highest standards to ensure a brilliant sparkle.
COLOUR
Another important quality characteristic of diamonds is the colour. The colour grade ranges from top-quality colourless D diamonds through the alphabet to yellowish Z diamonds. Dimexon’s assortments of melee diamonds are always guaranteed to be G+ in colour. We invite you to take a look at our pack shots of Stars-2, Stars and Full Cuts, so you can assess our standard colour assortment for yourself.
CLARITY
When we talk about clarity, this refers to any imperfections or inclusions in the stone. The grading scale ranges from FL or IF (internally flawless) to I3 (heavily included). Dimexon offers four clarity assortments in our online inventory: Clean, VS (very small inclusions), SI (small inclusions) and Top Piqué or SI3 goods (visible inclusions under a microscope). As a reference, we’ve organised some macro footage to showcase the clarities you can expect in all four assortments. As our assortments are well-known for their consistency, you can expect only slight variations to the examples showcased in the video footage.
CARAT
A carat is a measurement used to describe the weight of a diamond, or its calibration. The consistency of a diamond’s calibration, as well as its cut, can have a big impact on the average weight per size: a diamond with a poor cut might look smaller than a diamond with a smaller carat weight but better cut. Therefore, calibration becomes an important factor in comparing prices. As a professional, you are working to minute tolerances to make your designs perfect, which is why tight and correct diamond calibration is so important. This is why we focus on delivering perfectly calibrated stones consistently.
The size chart below will give you an idea of how many stones there are approximately per carat in each of our calibrated sizes. Please factor for small potential variances.
We are using I. David sifts for our melee calibration. Please bear in mind that small variations are possible between different siftsets.
An original parcel is a scoop of goods from a certain size-break. For example :
Stars -2 : 0.90mm - 1.25mm
Stars : 1.25mm - 1.80mm
Full-cuts : 1.80mm - 2.70mm
The mix will be as diverse on arrival from our manufacturing division. This means that some mm-sizes will be more available and others less.
Parcels are ordered per carat with a minimum of 5 carats.
Not yet. Melee diamonds are too small to be certified, but we do guarantee that all our diamonds are fully traceable, regardless of size. Please subscribe here and we’ll inform you once we change/expand our online offering.

Order Process
Placing an order is as simple as buying from any other online store. Just find the collection and diameter you are looking for in our shop, choose the amount you need, and add them to your order. It’s that simple.
At the moment, we offer four collections, made up of four specific clarities in a G+ colour range. We offer 36 items within each collection, and each item is a highly calibrated stone of a specific size.
Dimexon produces natural melee diamonds at a large scale, so we offer stones in qualities ranging from completely internatlly flawless down to commercial grade melee stones.
Because of the wide range in production, we use our own internal quality labelling which uses a scale from Q105 down to Q-25.
Clean: Q95
Fine: Q50
Fair: Q15
Commercial: Q-5
Feel free to contact us directly if you are looking for something outside of these collections.
There is no limit to the amount you can order. You can order any number of individual stones.
At the moment, we do not require you to order for a minimal amount before we ship. We do, however, charge $50 in shipping costs for orders below $500.
Because the use of USD is a diamond industry standard, and ensures prices are regulated internationally.
At the moment we only accept payment in USD. Conversions will have to be done through your bank.
When you’re ordering in USD/ct, the approximate number of stones that your order will contain will be indicated. When you order in USD/piece, the approximate number of carats it will sum up to will be indicated. In both cases, the approximate number can vary by 5% both up and down, so please take this into account.
All our orders are shipped fully insured at no additional cost (for orders above $500). Fully insured shipping on smaller orders is provided for $50.
For our European customers, we are using the logistics services of both Malca Amit and Ferrari. Both are value carriers and will insure the shipment until it is handed over and signed for by the receiving company.
Delivery
We aim to have your order shipped within 24 hours of it being placed. Subsequent delivery then normally takes between three to five business days.
We aim to prepare the shipment for delivery the same day the order was placed. We then entrust it to one of our shipping partners.

Origin & Supply Chain
The Kimberley Process Certification Scheme is the process established in 2003 to prevent "conflict diamonds" from entering the mainstream rough diamond market by United Nations General Assembly Resolution 55/56 following recommendations in the Fowler Report.
The SOW enables manufacturers to pass on the guarantees that they received by sourcing Kimberley Process Certified rough goods. After manufacturing, our invoices will state:
“The diamonds herein invoiced have been purchased or sourced from legitimate sources not involved in funding conflict, and in compliance with United Nations Resolutions and corresponding national laws. We, the seller, hereby guarantee that these diamonds are conflict-free and confirm adherence to the World Diamond Council System of Warranties Guidelines.”
Dimexon predominantly sources its rough diamonds from De Beers and Rio Tinto. We have been a De Beers Sightholder and a long term partner of Rio Tinto under the Select Diamantaire program for many years. Apart from these prime sources, we also buy rough from smaller mining groups through tenders.
Our diamonds are polished in Coimbatore, southeast India, where Dimexon was founded by Pankaj Kaushik Mehta in the 1960s. Our state-of-the-art production facilities are located at our spacious green campus and it has received appraisals by numerous independent auditors in the past.
We were one of the first suppliers to fully address Diamond Integrity Assurance by introducing 100% screening of all melee diamonds leaving our office. We’ve also assessed possible contamination points and installed systems and processes to guarantee 100% natural diamonds.
The screening process for stones between 1mm and 3.8mm takes place in-house and is executed using either De Beers-developed AMSII or HRD-developed M-Screen 4.0 technology. All stones smaller or bigger are screened at independent laboratories such as IIDGR (Forevermark) or IGI (International Gemological Institute).

All stones, smaller or bigger, are screened at independent laboratories such as IIDGR (Forevermark) or IGI (International Gemological Institute). All stones that are “referred” by the in-house machines as being suspected of not being of natural origin are sent to independent laboratories for further testing.
After polishing, all our diamonds are assorted by our own team of professionals at Diamoda, our assorting department in Mumbai, India. At the facility, we use Sortoscope technology to guarantee the highest levels of consistency in the industry.
