The Ophir Collection of rare gemstones, which has garnered nine Guinness World Record titles, is up for grabs to qualified buyers.

31 308 carats

Included within the collection is the world’s largest faceted sapphire, the Ophir Sapphire. Weighing 31 308 carats, roughly the size of a dinner plate, the extraordinary blue gemstone is recognised by Guinness World Records as the largest faceted sapphire in the world.

The Ophir Collection includes a total of 40 rare and exquisite gemstones, the majority of which are the largest known specimens of their kind in the world.

Certified by the GIA

All gemstones in the collection, with the exception of one, have been certified by the Gemological Institute of America (GIA), the world’s foremost authority on diamonds and coloured stones.

GIA, and several other leading authorities on gemstone identification, were unable to identify one gemstone in the collection, suggesting that it is a new mineral.

Ophir Mystique

Designated the Ophir Mystique, this unknown gemstone has the distinction of being both the largest – and possibly the only – specimen of its kind in the world.

Other highlights of the collection include the world’s largest cut brown sapphire, and the world’s largest cut Tanzanite, both of which have been recognised by Guinness World Records.


The Ophir Collection also contains numerous gemstones that are far more scarce, many of which, according to several leading authorities such as, are listed among the top ten world’s rarest and most valuable gemstones.

For several of the Ophir gems, there are only a handful of specimens known to exist. One such gemstone is the extremely scarce Musgravite. Described by GIA as a rarity among the rare, the Ophir Collection encompasses the three largest cut Musgravite gemstones in the world.


One of the rarest gems on Earth, as described by GIA, Hibonite is a virtually unknown gemstone, with only a few cut specimens known to exist. The world’s largest cut Hibonite, and the world’s largest faceted Hibonite, are both part of the Ophir collection.

In addition, the collection also contains extremely rare and valuable gemstones such as Grandidierite, Serendibite, Painite and Jadeite Jade, many of which are among the rarest and most valuable in the world.


A faceted Neptunite is so uncommon that GIA featured the Ophir Neptunite in an article published in 2013. According to GIA, at the time of publication, the Ophir Neptunite is believed to be the first and only faceted Neptunite examined by the renowned laboratory.
