The Guinness World Records world record for the largest carved sapphire is a multi-coloured (blue, gold, grey) polished rock that weighs 80,500 carats (16.1 kg, 35.49 lb). The sapphire was displayed during the annual Unifour Gem & Mineral & Jewellery Show at the Hickory Metro Convention, NC, USA on March 19 2005.

     Guinness World Records also recognized the world record for the largest cut brown sapphire; it weighs 5,905 carats (1.19 kg, 41.66 oz) and is owned by Ophir Collection, LLC (USA) on 22 February 2014. The sapphire is a variety of the mineral corundum, an aluminium oxide (α-Al2O3). It also contains elements such as iron, titanium, chromium, copper, and magnesium.

    Star sapphires have a milky quality caused by the mineral rutile. Its fibres reflect light into the distinctive star pattern.

    The stone was found in a mine near the city of Ratnapura, known as the City of Gems and at the centre of Sri Lanka's £70 million a year industry.

    The owner declined to say how much he paid for the stone, but explained he named it the Star of Adam following a Muslim belief that Adam arrived in Sri Lanka after being banished from the Garden of Eden. Local Muslims and Christians believe he first set foot on a mountain now known as Adam's Peak.
