Hmmm … “16 carrots” ? Carrots Definition & Meaning - Merriam-Webster
What standard was used to arrive at a Hardness value of “10” ?
What is “good” Thermal Conductivity in comparison with extreme Thermal Conductivity?
It is painfully obvious that the Clarity does not equal FL (Flawless).
Just my observations from within your posting.
I have Diamond selector II and it shows 10 as hardness and the diamond tester shows good thermal conductivity as diamond
further the stone is comparatively harder than corundum
The Stone is well trans loosen and there is hardly any inclusions
Being as kind and respectful as I can … You need to study a little more English, as words do have meaning; and a lot more gemology (science of gemstones) and metrology (science of measurement). The Diamond Selector 2 is a low quality made in China unit known for false positives. It doesn’t measure Mohs hardness on its painted on scale. It gives a relative Thermal Transfer score which depends on accurate calibration with a natural diamond to avoid false positives. Again, you are observing Thermal Transfer characteristics of your stone under test and NOT its Mohs hardness level utilizing the Diamond Selector 2 device. “Trans Loosen” in your sentence probably means Translucent. A stone must be TRANSPARENT in order to even have a chance of being IF (Internally Flawless in regards to Clarity). Again, words do have meaning.
That is certainly NOT what you have. The Largest known natural red diamond rough weighed 13.9 carats (finished polished weight was 5.11). Moussaieff Red Diamond - Wikipedia
Keep studying … you’ll get there.
you points are well put…takes a lot of study and experience to know gemmology… it’s a science.
have to know about chemistry and physics…to understand optical properties and physical properties, crystallography of gemstones. cheap testing equipment without know their action and limitations will be decieving!
Understanding color is even harder… trace elements, crystal field splitting, lattice dislocations…quantum effects.
Well Mr. Steven … I know that you have put your time in. You have a Scientific background and are well educated. I have enjoyed reading many of your replies on this forum. Keep up the good work. Michael in Las Vegas 
Far from it… to know things truly well, I would need to go back to school as a nontraditional student and relearn chemistry, physics, and progress to advanced math. Sitting in on the geochemical society lectures, where I am right now (annual Goldscmidt joint international and european geochemical societies— all PhD stuff, by professiona geologists) I can follow the gist of the information being presented, and occassionally the details, but the devil is in the details… doing the actual work is another matter… I took 2 semesters of inorganic chemistry, 2 of organic chemistry, 3 calculus and 3 of physics… some of it is retain but only in the context of what I have used daily…the rest of the details have been long forgotten as it was 50+ years that I was in undergraduate college preparing for an advance professional degree… thinking seriously of returning to school and doing a degree in geology as a non traditional student…I would have to start from scratch and relearn college algebra to rebuild my skills…my professional work was medical and medical science… entirely different from the physical sciences, yet still bound to the same scientific principles and methodology and standards… critical thinking and being able to evaluate scientific literature is a must… 10% of all scientific literature, by meta-analysis is “junk science”…being skeptical is a must also… people buy equipment without knowing how they work and what the limitations are… gem testers are based on thermal conductivity…good for diamonds and silver which have very high thermal conductivities… cheap testers will have difficulty with other stones… particularly those that have similar conductivities, which include most of the silicate gems and minerals…measuring SG can be done at home as royjohn instructed… the caveat is that the balance must be sensitive and well calibrated… a home scale has to be sensitive down to 0.01 grams… nothing less will suffice… people need to know what they’e doing, how to do it properly and what limitations there are before they start posting.
