A collection of 12 rough rubies from Tanzania is set to be auctioned in Dubai next month by SJ Gold and Diamond.

Central to the ‘Callisto Collection’ is a rough ruby with a variegated purplish-red hue weighing 8400 carats. Dubbed ‘Burj Alhamal’ (or ‘Aries’), the value of the gem is estimated at US$120 million (Cdn$151.4 million).

“The collection was initially a single massive stone, but was later cut into 12 pieces for logistical reasons related to transportation,” said SJ Gold and Diamond’s managing director, Patrick Pilati, at the collection’s launch. “Today, we unveil [its] star, which we called ‘Burj Alhamal,’ a rough ruby of 8400 carats weighing a whopping 2.8 kilograms.”

The collection is currently on display in the Dubai International Financial Centre. It is scheduled to be auctioned after Ramadan.

  1. I’m curious to know what makes this ruby in zoisite so special and expensive. I see the same material in Tucson for about $100/lb; a few exemplary specimens were $150/lb.

  2. The value is because it makes for good news. It really doesn’t appear to have an gem quality. From the pictures it might be an odd specimen but really it is nothing more than a large doorstop. Remember a few years ago, the world’s largest faceted emerald was on the market and tried to go to auction for one million? Never sold, and never had an offer. I would bet that emerald which was a few pounds could be bought for a fraction.
