Gemstone News · A Gemologist's Look
Infinity Gauntlets usually come from the toy aisle. This one came from a gem vault: East Continental Gems set it with six real, untreated gemstones totaling more than 170 carats, and it heads to auction at Julien's in Abu Dhabi on December 8, 2026. Here is what is actually in it, stone by stone, from a gemologist's point of view.

Stone by Stone: A Gemologist's Notes
Time Stone: An Untreated Colombian Emerald
The Time Stone is a nearly 23-carat Colombian emerald with no treatment. According to Julien's, it was found more than a century ago and spent more than thirty years in East Continental Gems' own collection, a stone the firm had long declined to sell.
Why that matters: emerald is a gem that is often clarity-enhanced. GIA notes that surface-reaching fractures in emeralds are sometimes filled with oils, waxes or resins to make them less visible. A large emerald documented with no treatment at all is the detail that made gemologists stop scrolling.
Space Stone: A Madagascar Sapphire
The Space Stone is a sapphire from Madagascar of more than 30 carats. Heat is the most familiar sapphire treatment; GIA explains that heating can intensify, or even create, blue color. Julien's states that this sapphire, like the other five stones, has not been treated.
Reality Stone: A Mozambique Ruby
The Reality Stone is a natural ruby from Mozambique of more than 15 carats. It is the lightest stone in the glove, which says more about its neighbors than about it. Rubies are commonly heated to remove purplish tones, and some are fracture-filled with glass, both according to GIA. An untreated ruby at this size is a serious stone.
Power Stone: An Amethyst
The Power Stone is an oval natural amethyst of more than 35 carats. Amethyst is the purple variety of quartz, and it is the one gem in this lineup most people have already worn. Seeing it at this size, in a deep purple, is a good reminder that a familiar gem can still be a showstopper.
Soul Stone: A Spessartite Garnet
The Soul Stone is a cushion-shaped spessartite garnet of more than 35 carats. Spessartite (also called spessartine) is the orange member of the garnet family. Most people picture garnet as dark red, which is exactly why this choice works: that orange fire is the Soul Stone.
Mind Stone: A Yellow Diamond
The Mind Stone is a rectangular brilliant-cut yellow diamond of almost 35 carats, described at its 2022 debut as "high clarity, intense color." Like the other five, it is certified by AGL, and it also carries documentation from GIA.
Why "Untreated" Is the Headline
Gem treatments are normal and, when disclosed, perfectly acceptable. Heating, oiling and filling are long-standing practices, and many beautiful pieces in the market have had them. Julien's put it plainly: nearly every gemstone on the market has been treated or enhanced, and these six have not.
That is what makes this glove interesting to a gemologist. The carat total gets the headline, but the lab reports get the respect. Six large stones, each certified, none of them treated, in one object: that combination is rare.
The practical takeaway for your own jewelry: always ask whether a colored gemstone has been treated, and what the documentation says. A good jeweler will tell you without hesitating.
Who Made It, and Where It Is Going
The idea started in 2019, when East Continental Gems CEO Adam Mirzoeff spotted a toy Infinity Gauntlet on a Marvel executive's desk and half-joked that they should make a real one. East Continental Gems, a family-owned New York firm working from the same office since 1972, did exactly that, by agreement with Marvel and Disney and with access to Marvel's own design files.
- Size: nearly 20 inches tall, so every stone had to be large enough to read from across a room.
- Debut: unveiled at San Diego Comic-Con in 2022.
- Paperwork: AGL certification for each stone, additional GIA documentation for the diamond, a certificate of authenticity signed by Jim Starlin (creator of the original Marvel Comics Infinity Gauntlet storyline), and its original fitted presentation case.
- Auction: a headline lot of Julien's Auctions' Pop Culture Legends Evening Sale, Tuesday, December 8, 2026, at Rosewood Abu Dhabi on Al Maryah Island. Bidders must be pre-approved by Julien's.
