Prominent factors that decide Gemstone Cutting & Polishing

The best aspect of owning and dealing in gemstones is the fact that they can be cut into delectable shapes and patterns. How a gemstone will look once it is polished is the most important part of cutting and polishing it. The way a gemstone can be cut depends on many factors. Prominent factors that decide the gemstone cutting and polishing are:

  • Size of the rock
  • Weight of the gem in carats
  • Irradiance required from the cut stone
  • Hardness and durability
  • Colour stability
  • Matching pair compatibility

Even the best of gems can look flaccid and lifeless if not shaped in order of their desirability. Gemstone cutting of amethyst, diamond, topaz, cat’s eye and sapphire is done on the outside facet to match with the inside pattern. The bottom facets have to be cut in shallow angles to allow maximum refraction of light through the gem. Maximum glitter and brightness is achieved when light passes through the gem surface without being blocked by a “dead spot” at the centre.

Gemstone as a gift: Tip for the first timers

Shopping for a gemstone? Yes, you would need an eye of a perfectionist to lay your hands on a flawless gemstone. Meanwhile, lapidary artists recommend that you buy a flawed gem, only for one reason. Perfect gems are artificial, while the flawed ones are natural. In the gem market, a natural stone would garner more price than a polished, synthetic rock.

Where to look: Variety you can try

Diamonds and pearls remain the top choices. But if you are looking for a good gem in your first buy, start with Citrine, amethyst and other members of the coloured quartz family. Beryls come very close to quartz family as far as popularity is concerned. Preferably, Rose quartz and purple-Blue amethyst are best options for you to buy at a reasonable price. If you are wish to gift them for anniversary or as a wedding gift, go with a stone that weighs at least 3 carats. 15mm stones are winners on every occasion.

Stones from the Exclusive families

Rarer gemstones are hard to find and hence are costlier than the contemporary stones. Sapphires, rubies and ambers are popular, but if you are looking for something exquisite and invaluable, we recommend you to look beyond the usual shades and varieties in gemstone cutting market.
