The right size is one that slips on to the finger with a little effort. Easy slip on or slip out is not advised as they may fall off as you carry bags, open doors and so on.

Experienced, smart sales team members will allow you to try 5 different sizes before they or you decide the right size for you.

At times we will be able to approximately judge for you the ring size from a photograph of the hands, although it will not be the perfect way, you may exchange the ring you buy after the surprise day/ event.

When to remove your beautiful jwellery

Mist jewellery may be worn 24x7. However remember jewellery is made from amongst the softest of precious metals – Gold, Silver & Platinum, in that order. These soft metals will scratch easily. Multiple minute scratches will dullen or take the sheen away. Therefore:

  • Do not ‘dump’ one piece of jewellery on another.
  • We advice each piece of jewellery be kept with some space or thin soft fabric between each piece.
  • Protect the gemstones. Every gemstone is soft. Some are softer than others.
  • In order of softness:
  • Diamond, although they are brittle, hence can chip in corners if dropped.Ruby & Sapphire.
  • All other transparent gemstones.
  • Emerald.
  • Porous gemstones that include: Pearl of all kinds, coral of all kinds, turquoise, malachite.

Links getting loose, Strings sanpping, Clasps opening up, Stones falling, Sizes & length preferences change, Tarnishning of metals.

  • Jewellery is normally made up of several links put together. Hence, with use, with stretching, some links may open up or get too tight.
  • Strings of beads, pearls, corals will wear out with time. Periodic restringing is necessary.
  • Clasps with use may become less strong or may become too strong.
  • Some metals, specially if silver is present, may tarnish with time.
  • These are exactly the reason C Krishniah Chetty Jewellers offers a complementary cleaning, maintenance lounge in each of their showrooms & boutiques or a mail-in service for clients who do not have our stores close by. Our trained staff will ensure each piece is thoroughly checked, and appropriate action is taken to help protect the life of your precious jewel. The service is complimentary. If any parts, components, additional leave-in services are required, they will be charged extra with your prior consent.

Remove Jewellery during heavy or moderate tasks

Jewellery ought to be removed and stored carefully before getting into moderate or heavy tasks such as at a gym, while handling vibrating equipment, while rough riding, sports & such activities for the same reasons stated earlier.F

Jewellery should be put on last & taken off first.

Jewellery ought to be worn last after you make-up your face, after you’ve sprayed on perfumes, colognes, hair sprays, and the like. The chemicals in such cosmetics may discolour jewellery at times. Cleaning your undersurface and tops & sides before storing them back into the jewel cases will increase the good life of your precious jewellery.

No jewellery Into swimming pools, spas.

Chlorine in water will reduce the life of fine jewellery hence try not to use them in this condition.

Jewellery is best before a bath.

Open sinks in wash basins, in showers can wash away a loose diamond if loose in their setting. Hence as a precaution, it’s best to remove the jewellery before a bath. Further soaps, shampoos, conditioners may contain chemicals that may discolour, or with regular baths ‘melt’ away minute amounts of porous gemstones. Soap is also ‘oily’ thereby deposition of thin layers of oil on diamonds & gemstones will make them appear dull.

Jewellery cleaning cloths sold online here or at our showrooms & boutiques are best for cleaning

Special cloths, with minimum fibres are best for cleaning jewellery & restore their shine. Available for between Rs 300 & Rs 1000 each Click Here

Warm water immerstion (for non porous gemstones) is best for cleaning your jewellery.

Warm water immersion for just a few minutes help remove soap, if any, stubborn dirt, and the like. Using a soft, really soft, brush will help remove stubborn dirt from the intricate portions between prongs, the crowns, & setting portions.
