How are Diamond Rings made? 

WALT: Use language features

WALT: Paragraphing

Paragraph 1- Introduction

A diamond ring is a type of jewellery that features a diamond. Diamond rings come in many different shapes, sizes, and colours.

Paragraph 2- Different shapes and colours of rings

Some of the colours of diamonds are: siam, ruby, garnet, sun, Indian red, clitrine, peridot, olivine, emerald, sapphire, turquoise, cobalt, amethyst, violet, rose and many more. Shades of rings are, faint, very light, light, fancy light, fancy, fancy intense, fancy vivid and fancy deep. The shapes of different diamonds are round, cushion, princess, asscher, heart, pear, emerald, radiant, oval and marquise. 

Paragraph 3-How is the diamond formed

Diamonds are a mineral of carbon. They are naturally formed in the earth's mantle. Once they are fully formed, they are pushed to the earth’s surface by a volcano. After a volcanic eruption, diamonds of all different shapes are scattered on the ground.

Paragraph 4- How the ring is made 

Firstly, the ring is sketched out in the design that has been chosen. Next, a 3D generated model is made using a printer. It is then sent to a 3D printer for physical printing. Then a waxing machine is used to make a thin wax model, layer after layer. Two different types of waxes are used to make the model, a blue casting wax on the inside and a red support wax on the outside of the blue. It takes 18 hours for a ring model to print. The model is then put in a bath containing a cleaning solution. Then tweezers are used to get rid of the stubborn red wax.  The model is then attached with other ring models onto what is a tree for rings. They are attached so that many rings can be made all at once. The tree is then covered in plaster and is placed in a clome for many hours until the wax burns out. The metal needed to cover the ring is then chosen out and melted with fire. A temperature of 1064.444 degrees celsius is needed to melt gold and the temperature of 1768.333 degrees celsius needs to be reached to melt platinum. After the desired metal has been melted, the metal is poured into the mold and placed in cold water to cool down and harden. Then the casing is removed and each ring is carefully taken off the ring tree. The ring is then sent to be cleaned and get ready to be sold. Files are used to get rid of the sprue that connected the ring to the tree. The support bar is then separated from the ring and the ring is sanded to make sure there are no rough edges. Finally, a hammer is used to make sure the ring is the right size and shape.  After the ring has been shaped properly, it is sent for a pre-polish by a buffer. A green rouge polishing compound is added to help make the metal shiny. The ring is then rinsed in an ultrasonic bath made of mainly water and soap. At the store, the completed ring is received and the stones are picked in the correct size and shape. After that, the diamonds are carefully checked to make sure they are perfect. Once the correct stones are selected, the stones are ready to be placed onto the ring. A shellac wax is used to keep the ring in place. It is heated and shaped around the ring. The diamonds are then hammered into the right spots and are secured with prongs to make sure they stay in place. Lastly, the completed ring is sent for a final polish, making sure it shines like a star. 

Conclusion-

Now you know how a diamond ring is made. I hope that when you get a  diamond ring, you take special care of it because it takes a lot of work to make and costs a lot.

A day in the life of someone facing water scarcity

Bring, bring, bring. Hi my name is Kriti Kapoor, I am 16 and I live in Chennai.

 I wake up early in the morning at 5 o’clock.  It is boiling hot and extremely sunny yet again. Every morning when I wake up, I am hoping to see rain or clouds but it never comes. I am always thinking that rain will come in the morning, but no. Everyone is desperately waiting for the monsoon season here in Chennai. Sometimes no rain comes on monsoon season.  My family and I are desperate and anxious for enough water to last us a week as I have to go and buy a big bottle of water. 

Paragraph 1- waking up

I get out of bed and dip my tooth-brush into the big tank of water in the laundry to last  about two days. Then tomorrow I will have to go out and get another lot of water to last the next two days. After brushing my teeth I get a damp cloth and dab my body so I can save my water. Then, as I am cooking, I hear my neighbours shouting at one another.

“HEY THAT’S MY WATER SO DON’T TOUCH IT AND ANYWAY I PAID FOR IT YOU DIDN’T”.

I YIY YIY, I say to myself when is all this fighting and lining up for water going to stop. I obviously hope it ends soon so I can get some peace and quiet.

Paragraph 2-morning routine

Yessssss!!! Finally the water truck has come. Oooh my god,   I almost forgot about my breakfast . I make breakfast for my parents and younger siblings, Adity who is only 1, Mahika who is 3, Akriti who is 9 and Sonakshi who is almost  15. For breakfast I have made dosa, fried potato and some peanut chutney, my favourite. “YUMMY!!!!! Since my mum and dad are at work and I need to get water, my patti ( what we call our mums mum in tamil) will take care of my youngest siblings and will be waiting for me.. Ok, now I am back from collecting water for about a few days.

Paragraph   3- school and lunch

Since we don’t have to necessarily go to university, I don’t go.

I take care of my two siblings who don’t go to school at the moment as they are too little to go. (1 hour later). It is time to make lunch. I have to make a lot to last for dinner too. I am going to make butter chicken, my favourite. YEEEEEEESSSSSSSSSSSSSSSSSS!!!!!!!! Ok, now it is time for me to make some delectable butter chicken then eat it. So, after  making and eating it, I start tidying the house and putting my tiny, cute siblings to bed before my mum, dad and annoying, naughty little siblings come home from school.

Afternoon time and before bed routine

All my family is now home. I need to go off and help AKriti and Sonakshi with their homework that is going to extremely exhausting. It is finally dinner, something I have been longing for. After dinner, my family and I  watch TV in the living room. I like family tv time because it is as fun as being in candy land. After family TV time, also known as ftt, It’s time for bed. 

GOOD NIGHT!!!!!!!! 

Conclusion

Overall my day was pretty good and I enjoyed it. I mean, even though my day was the same as any other week day, it was still fun. BYe and see you next time!!
