Generally, transparent gemstones are faceted and polished into cut stones.Coral is an opaque gem. It is never found as transparent. Hence, coral is always cut into cabochons and beads. some times it is also carved.

Big sized coral cabochons are used to make rings, pendants etc. Small sized ones are studded into ornaments with some other gemstones or diamonds. It is also used in India for making Navaratna jewelry.

Coral beads are used for stringing and making beaded jewelry. There are beautiful carvings in coral and those are also used in making fancy jewelry. People often use coral figures as decorative.

Dear Roychoudhury,

Thanks for comment. The artisan is polishing a ruby rough that is coated with black foreign material. Of course, this gemstone is not coral(in video Shaping gemstones).

I apologize that I do not have any video of coral manufacturing. However, most of the Gemstones are shaped in similar way.

Thanks,

Jyoti Kothari
