Concrete is formed from mixture of different elements of several hardness and specific gravities that change from geographical region to region. Use of such hardness pencil is limited to providing a general guide for surface harness as per Moh’s scale of hardness.

 

Steps involved in testing hardness:

1.   1.    Start with a hardness pencil with the highest number than the surface being tested is believed to be. For beginners, start with hardness pencil No.10 until more experienced and you have a general feel for the concrete in your geographical location.

 


2.   2.     Hold the hardness pencil in the same fashion as you would generally hold a pen for writing and place the edge of your palm on the floor as if ready to write.

 


3.   3.     Reach forward with the hardness pencil and draw a small straight line towards you using the same downward pressure you would use generally while writing with a pen on paper.

 


4.    4.    You will notice the No.10 hardness pencil will easily produce a scratch. Subsequent hardness pencils will leave less and less prominent scratch. Please Do NOT force any of the hardness pencil to scratch which may damage the tip of the hardness pencils.



4.

5.    5.    Continue down through the various lower hardness pencils until you come across the hardness pencil which will not scratch the surface. For example if no. 6 leaves a scratch but No. 5 does not, then the ground is about 5.5 on the Moh’s scale of hardness.

 


6.   6.     Sometimes the metal from the hardness pencil may lay down and look like a scratch. A small hand glass or a 10x loupe will assist you to ascertain the scratch or line left by the hardness pencil.

 

 


7.    7.    If you are unsure whether the hardness pencil left a scratch, lightly drag the hardness pencil perpendicular across the first line. If there is a scratch, you will feel the tip of the hardness pencil drop into the grove.

 

8.  8.      Always test in 3 – 4  locations of the ground so as to conclude a more accurate result. There could also be quite one pour present in several areas of the ground, which can give widely varying results.

 

 

9.   9.     Carefully check for signs of micro-topping, self leveling or filling/patching of compounds. Scrutinize at different colors, textures or possible edge delaminating for clues.


10.    To increase your knowledge of the aggregates used in your geographical location, do a scratch test on individual stones that are exposed during the grinding, polishing process of your routine.


11.    The hardness pencil should always be sharp and in good condition.

 

12.   The hardness pencils has extremely sharp points, hence proper care should be used when handling them.


13.    Never place a loose hardness pencil in any pocket or article of clothing which may damage the tip of the hardness pencils.


14.    It must be remembered that the hardness pencil and instructions are only a guide and DO NOT cover every possible situation.

Guide to buying gemstones & jewellery online.

 

Guide to buying gemstones & jewellery online.

When it comes to buying any gemstones, most of the people today prefer to take their search online. With the option of endless leads and competitive prices offered, it becomes convenient for the customer to buy online. But many of the online purchase had some or the other bitter experiences.

We spoke to Kaushik Sanghvi (Graduate Gemologist, F.F.I.G) from Mahavir Gems, who is a third generation jeweler and has been training & educating students from last 25 years in various subjects in gems & jewellery field. Mahavir Gems is one of the top gemstone retailers online from Mumbai (India) on major search engines. Kaushik Sanghvi gave us some expert guidelines on how one can safely buy gemstone jewelry online and avoid any bitter experience.

So the first question is, why should one buy gemstones online?

Basically while searching online, one is exposed to a option of wide variety of gemstones & jewellery designs and fusions, from various suppliers while sitting at your convenient location and time which is normally a limited choice in the shops. This adds to time saving as one does not need to visit various shops. At the same time online stores saves on various operational costs like sales staff, rent, display light bills etc. compared to shops, hence they can offer competitive prices as well.





What should one be aware of when buying gemstones online

Knowing from whom you are buying and making sure that the seller is trustworthy is most important. It’s always advised to read customer reviews from a reliable search engines, that will help you to get better insight into the quality of the jewellery /gemstones sold. In addition to this, don’t forget to go through the vendor’s return policies that even help you in understanding whether the gemstones you end up buying are recycled or new and check if the item comes with an authenticity report and relevant certification on your name.









What should one expect from the retailer to make the purchase?

Clear images with normally white background from multiple angles, a surround 360-degree videos and in-depth product details will all help you to make an informed purchase decision. One can even request the seller to send a actual image/Video (without enhancement) on mobile before finalizing the selected gemstone. An online jeweler who offers specific customization options goes the extra mile to make sure 100% customer satisfactions.

The website should also be user-friendly and facilitate the experience with excellent customer service.

How does one know that a gemstone is genuine and not fake?

It is practically impossible for the customer to judge whether the gemstone is natural, synthetic (lab grown) or an imitation (fake) by just looking at it. A gemmologist with his knowledge & experience is the one who can actually differentiate between the three. Hence choose a supplier who is either himself or has employed experience gemmologist at his end.

 




Natural gemstones evolve in nature, and can be achieved by mining or exploration, whereas lab-created gemstones are the one that are constructed in controlled environments in the laboratory. Fake or imitation stones are usually any stimulant made of plastic or glass. As natural gemstones are formed naturally, they are bound to have imperfections or inclusions. Lab created gemstones, on the other hand, will almost always be perfect until and unless there are some imperfection intentionally created. A key for reference could be used in such case, “Too Good To Be True”. If someone offers at very cheap rates, as Natural Gemstones are always costlier than its counterfeits & stimulants.

Do gemstones come with a lab report just like diamond?

All gemstones just like diamonds come with a lab report. A certificate of authenticity and third-party appraisals for both diamond and colored gemstone jewellery is supplied by reputed jeweler like Mahavir Gems. This gives an extra confidence and surety to make your purchase online acknowledging you the authenticity of your gemstone and its value.

How does gemstone report impact the value of a gemstone?

Gemstones, just like diamonds, are also graded on the basis of its color, clarity, cut and carat weight, but obvious, higher the grade of the gemstone, the higher will its value be.

The prices are totally based on these factors hence; one can decide the purchase of the quality of the gemstones depending on the budget.

Should I be able to return my gemstone, if it doesn’t meet the details mentioned?

Yes, you should absolutely be allowed to return your gemstone jewellery if you are not given the things as per the details mentioned in the listing.

One should buy from jeweler who allows to return the item for a full refund if they fail to meet the details mentioned in the listing. The period for returns differs from vendor to vendor and can range somewhere between 3 to 10 days.

What gemstones should I buy in 2021?

Peridot is one gemstone most of the woman would prefer in this 2021. Apart from this, citrine, sapphire, tanzanite, opals, aquamarine, onyx, garnet, emeralds, topaz, tourmaline, amethyst, morganite and ruby are sure to appeal the customers.
