Detailed Product Description
This Burma Blue Sapphire (Neelam Stone) weighs 8.27 carat (9.09 ratti) and measures 12.60 x 11.40 x 6.00 mm, with a light blue colour and an octagon mixed cut. It comes with a lab report from The Standard Gem Testing Laboratory, which identifies it as natural blue sapphire and records it as Un-Heated & Un-Treated. Its Burma (Myanmar) origin is declared by Ratna Gems.
Blue sapphire, known in India as Neelam (also spelt Nilam), is the blue variety of corundum, coloured by traces of iron and titanium. Burma, now Myanmar, is a historic sapphire source in the gem trade; each stone's value depends on its own colour, clarity, cut, weight and treatment. Synthetic sapphire can be very convincing, so a laboratory report is the most reliable confirmation of a natural stone.
Appearance
This stone's report records its colour as light blue. Blue sapphire ranges from greenish blue to violetish blue, and natural sapphire typically shows some inclusions, fine silk, colour zoning or small variations in shade. Check this stone's colour, cut and actual look in the photos and video before choosing it.
Traditional Use
In Vedic astrology, blue sapphire (Neelam) is traditionally associated with Saturn (Shani), and it is one of the nine gems of the Navratna. Customers buying it for astrological use usually follow their astrologer's or Pandit ji's guidance. Blue sapphire is also the September birthstone.
Care
Sapphire is 9 on the Mohs scale, with excellent toughness and no cleavage, so it suits a ring or pendant with normal care. Clean it with warm soapy water and a soft brush, dry it with a soft cloth, and store it apart from diamonds, which can scratch it. Avoid harsh chemicals, ask a jeweller before using an ultrasonic or steam cleaner on this stone and its setting, and tell your jeweller it is a sapphire before any setting or repair work.
