Diatomography-S: Colorless (D to Z) Diamonds - Rough Planning & Plotting to Polished Manufacturing
Lemon TechnoMist (LTM) is a company specializing in rough diamond design and cutting & polishing Services. Rough diamond planning is the most important stage in entire chain of manufacturing because of its position to analyze various plans and select the best plan out of it. If the stone is not planned properly, the final output will be suboptimal and nothing can be done to rectify the situation at the execution stage or afterwards.
In days to come, more and more of the planning shall be done and finalized with the help of advanced technologies like M-Box, Helium, and now IG planning & plotting. However, the use of the technology correctly is also a huge challenge for most companies because of lack of trained manpower. Moreover, since the technology keeps on ever evolving, it is very difficult for companies to keep abreast with it and there is always a time lag between the up gradation of the technology and its correct application by the users.
Using our proprietary technology, we are able to pre-estimate the final colour of the stone and its various combinations based on shape, size, cut etc. Thus, instead of manual judgment, we use science to design a stone to optimize its value based on all possible parameters i.e. cut, clarity, colour, shape etc.
After planning and designing services, our expert well trained polishers give a real shape to the rough stone as per instruction and designed passed by planners and quality checkers. Years and years of experienced workers are hired who have been trained by our experts by which they are in a position to polish best quality stones.
LTM welcomes stones for full polishing, half polishing and already polished stones for Re-Imagineering to achieve desired results.

Diatomography-S: Fancy Color Optimization and Manufacturing
Diamond Cutting and Polishing may be a very taken for granted activity and many organizations today possess unparalleled expertise in the same. However, when it comes to precision manufacturing in case of Fancy color stones, there is a huge vacuum. Neither the art of such manufacturing has matured nor there any scientific knowledge about the same. The manufacturing of especially fancy color stones is more a trial and error phenomenon.
LTM strives to take out the trial and error from such manufacturing. With application of scientific principles of color optimization to get better color, dense saturation and even dispersion of the color which can lead a stone to substantial value enhancements to the stone by transforming a light colored stone to intense or intense stone to vivid color in case of fancy colored stones and from a lower to a better color for a D~Z stone.
LTM uses advance computing algorithms and technologies to design a rough stone to optimize the color performance of the stone, in terms of either reducing saturation or enhancing the color saturation. This is very specialized service for stones which are in color range of F to Z or have fancy color prospects.
We use the best possible advanced technology and expertise for getting the best results with continuous effort on research and technology and parallel discussions with laboratories such as GIA, IGI, HRD laboratories.
Having optimizated and polishes 1000s of stones based on our unique approach and proprietory technology, LTM has developed a unique workshop of Fancy colour optimization and manufacturing processes through the best technical aid which are ahead than any technology in the market.

Re-Imagineering Services
In many cases of polished diamonds certification, in house analysis of cut, symmetry differs from the analysis of GIA, IGI, HRD results. And diamond manufacturer ends up with repairing of polished diamond to reach near the result given by GIA or other labs. But not every individual manufacturer can estimate the exact percentage of repairing or what effort has to be put behind repairing of polished diamond.
GIA has used certain proportion measurements obtained with non-contact optical scanners to grade the cut of round brilliant diamonds. Improvements in the operation and accuracy of these instruments now enable us to also measure some symmetry parameters during the grading process.
Therefore, many diamond manufacturers are now-a-days in a position to predict GIA symmetry grades from measurement data, so they can apply these considerations during planning and cutting. Likewise, makers of non-contact optical scanners have been interested in guidelines for how measurable symmetry parameters affect the GIA symmetry grade.
The grade services presented here offer a substantive estimate of the symmetry grade for any round brilliant cut diamond.
LTM measures the diamond’s Cut grade according to most major gem labs (GIA, IGI, HRD, etc.), explains the Re-Imagineering potential of your diamond and derives detailed Re-Imagineering instructions for improvements with highest cut grade with minimal weight loss. This also increases the polishers' confidence and saves time and money like avoiding re-certification cost of your diamond.
D to Z Color Confirmation Services
The D2Z Service confirms the colour from D to Z range in Colourless diamond using LTM’s proprietary and advanced technologies.
The D2Z Diamond Report captures the unique characteristics of diamonds distinguished by hue, tone, and saturation. This report contains all of the classic diamond report measurements. Plus, it includes colour-specific criteria such as absorption spectra, colour distribution, colour grade, and colour origin.
LTM D2Z Grading Report includes an assessment of a diamond’s colour along with a plotted diagram of its colour characteristics and a graphic representation of proportions. For standard round brilliant cut diamonds falling in the D-to-Z colour range.
IF Clarity Confirmation Services
LTM provides a specialized service of IF clarity grade confirmation from Rough stage. Normally, diamond traders and manufacturers are not able to get precise results from rough stage for getting IF clarity during processing.
It is possible for diamond manufacturers to do high quality Rough Planning for estimating the clarity and other parameters of a diamond by using different technological aids. But for IF clarity confirmation, one may have to wait till the stage of star and halves polishing.
In this regards, it may be very useful for manufacturers / traders to get IF confirmation analysis from stage of Rough Blocking. LTM can provide this service of IF clarity grade confirmation at the rough diamond blocking stage.
IG Auto plotting & Planning
LTM provides service of IG Auto Plotting, planning and marking for the stones submitted for Auto plotting and Quality Checking with marking on it.
Using this technology, we can auto plot the inclusions in the stone without making any windows and without leaving any marks or traces on the stone.

1. Captures images for Auto Plotting of inclusions under immersion glass
2. Very high depth of sharpness for better viewing of inclusions
3. Works in conjunction with Helium Rough and M-Box Scanner
Diamonds Audit Services
Value Proposition
Rough diamond planning is the most critical link in the entire diamond manufacturing cycle. Maximum value is added (or destroyed) to a rough diamond stone at the rough planning stage. If the stone is not planned properly or if the design is flawed, the final output will be suboptimal and nothing can be done to rectify the situation at the execution stage or afterwards. This fact is well realized and appreciated by all diamantiares. And therefore they have laid a lot of stress and focus on this critical function. Huge investments have been made by all companies in planning and design equipments and technologies. However, this does not ensure optimum planning. There is always a lag between the invention of a new technology and its right use by the user industry. This is because; ultimately it is the people who have to operate the equipments and technology. And wherever there is human intervention, there is a possibility of mistakes, errors, misjudgments and sub-optimal output or results.
An audit service to check the final design output is a solution to the above problem.
This audit service can help your organization in the following multiple ways :
It enables you to get the maximum value out of the audited stones.

Diamond Type Identification
We give service for Diamond type identification, so that HPHT & CVD diamonds can be easily separated from Natural Diamonds.
The issue of synthetic diamonds has become extremely important and contentious in recent times. There are lot of negative events and news flow affecting the consumer confidence of the trade. Detection of synthetic diamonds is the key weapon to fight this menace. However, the technologies prevalent today cannot with 100% precision, determine whether a diamond is a synthetic one. But there are technologies to determine whether any diamond is a type IIa diamond or not. Less than 2% of all natural diamonds are type IIa and synthetic diamonds are all IIa. Thus, identification and segregation of type IIa diamonds and their further analysis can lead to a fairly accurate detection of synthetics.
With enormous experience and based on years of research, Lemon TechnoMist can analyze the type of a diamond. Knowledge about the science of diamonds, light performance, colour, luminosity and the likes, and expertise to use the available technologies, in some cases, even before they are commercially available, enable LTM to add value to the subject and detection of synthetic diamonds.
LTM has its own in-house lab for providing this service as an outsourced agency and can also assist companies in setting up and operating their own inhouse screening facilities. We believe that we are uniquely positioned to provide tremendous value to our client through this service due to:

Videography and Photography for Colorless & Fancy Color Rough and Polished Diamonds & Jewellery
Diamonds are unique due to their breath taking brilliance, fire and scintillating performance. The value of diamond depends on 4Cs. In this regard, the lab grading reports and their numerical data are incomprehensible to most retailers and consumers. So a better way to raise efficiency of colorless and fancy color diamonds and Jewelery sales via on-line business to business (B2B) and business to consumer (B2C) is via high quality images and especially video.
Images tell only half the story, as most of the beauty attributes are dynamic and can be appreciated in sterio environment. So a dynamic display of the polish diamond and Jewelery can gradually improve on-line appraising.
Movies made by diamond cutting and Jewelery manufacturers can be used to sell via B2B, provided a consistent standard is maintained. The very same movie can be used by a retailer to sell a diamond or Jewelery to his customer.
The result of Lexus Softmac efforts is the “Di Box for Photography” - www.lexusindia.in/products/gb-DiBox.aspx and “Vi Box Technology for Videography” - www.lexusindia.in/products/gb-ViBOX.aspx
'In a business where most of one's clients are located in - often remote - foreign markets and countries, you need such services that would enable clients to view your diamonds from every angle, just as if they are holding the stone in their own hands.
