Author's Note – Please read this

I am regularly contacted regarding the value of this or that giant corundum crystal (or even cut stone). Sometimes red, sometimes blue, virtually all are offered with inflated appraisals vastly overstating their true value. The most common scenario is a large ruby-in-zoisite from Tanzania being offered as "Burmese."

I would like to set the record straight once and for all. Such stones are not worth millions of dollars, nor are they worth hundreds of thousands. Indeed, it is the rare stone that would be worth even US$10,000.

The simple fact is that not all ruby is valuable, not all sapphire is valuable. In order to qualify as a gem, a specimen has to have the proper combination of fine color and high clarity. Such large corundum crystals (and cut stones) have a clarity and/or color so poor that it precludes them from being used as gems. But don't take my word for it. See for yourself. If you have such a kilogram-sized piece, slice a small piece off and have it cut. Then have it appraised by a legitimate appraiser (not a scam artist).

Whenever possible in the tables below, I have listed actual sale prices. These are the only true measure of a gem's value. All of the rough specimens listed in the Rough Corundum Giants table are not of gem quality and thus have no gem value (despite what an accompanying appraisal might say).

For more on this, see my article: "Big Time."

Rockefeller Sapphire 62.02 ct; faceted, rectangular step cut; mounted in diamond ring; John D. Rockefeller, Jr. puchased this sapphire from a maharajah (rumored to be the Nizam of Hydrabad) in India in 1934; it was recut by Reginald Miller from 66.03 to 62.02 ct in the early 1970s; sold to Ralph Esmarian at Sotheby's St Moritz, Feb. 20, 1988, for $2,828,546 ($45,607/ct). At Christie's NYC 11 April, 2001 sale, it sold for $3,031,000 ($48,871/ct) (Lot 435). Former per carat and total price world record for a single blue sapphire. The following details are from Christie's: In 1934 John D. Rockefeller, Jr. purchased the sapphire from the an Indian Maharajah rumored to have been the Nizam of Hyderabad through Raymond Yard who advised him on many of his jewelry transactions. Raymond Yard was also a close friend of Raphael Esmerian (1903–1976), the world's leading gem dealer of his time. Esmerian would appraise it on a regular basis. This was an opportunity for him to look at one of his favorite gems and to speak of the stone's perfection. In the early 1940's Esmerian was consulted by Pierre Cartier to improve the stone as it was to be remounted as a brooch for Rockefeller's wife, Abby Aldrich Rockefeller (1874–1948). Cartier recut the stone to approximately 66 carats and made a brooch with calibré-cut sapphires and diamonds. In the 1950's Rockefeller's second wife, Martha Baird Rockefeller (1895–1971) had the brooch redesigned by Raymond Yard. In the winter of 1971, the Rockefeller family sold the jewelry from John D. Rockefeller, Jr.'s estate in Zurich. The sapphire was purchased by Raphael Esmerian for approximately $170,000 and then sold the following year to an Italian private client. Upon this man's death, the family consigned the stone once more for auction in the spring of 1980. This time it was bought by Ralph Esmerian, Raphael's son, for approximately $1,500,000. Ralph Esmerian has continued his father's legacy by dealing in rare gems and exquisite objects in New York. It was after this purchase that the stone was repolished to it's weight of 62.02 carats and mounted in a platinum ring. In 1986 it was sold to an American private collector who only collected stones of the highest caliber. Other gems in his collection included the Ashoka, a superb D color, Internally Flawless diamond of 41.37 carats, a 20.00 carat square-cut pink diamond and an extraordinary green diamond of 3.02 carats. In 1988, this collection was sold at auction in St Moritz. The Rockefeller sapphire fetched a world record price of $2,850,000 and was purchased again by Ralph Esmerian who sold it to its present owner.

World's Largest?

AMONG the most difficult tasks facing the gemologist is that of testing the world's largest. 'Tis not a task for the meek; those called upon to test the world's largest somesuch are rarely showered with trust. All specimens are "priceless" and all are "absolutely genuine," having been either family heirlooms dating from Timur's sacking of Delhi in 1398 AD, or recently unearthed from someone's backyard or rice paddy. Thus the owner often demands to watch the proceedings, fearing that, if their back is turned for even an instant, the vulpine tester will slide an identical specimen out from under his cloak for the switch.

During the author's many years practicing gemology, people constantly turned up with the "world's largest" this or that. I've been privileged to examine the "world's largest ruby" (a large chunk of battered red glass), the "world's largest imperial green jade" (a large chunk of translucent green glass) and the "world's largest sapphire" (a large chunk of battered blue glass). But perhaps most impressive of all was the "world's largest pearl." So large was this that a fruit scale had to be used to determine its weight. Indeed, it was a pearl of sorts, but, to be frank, that may be an abuse of the term. It actually resembled something extruded from the rear of an enormous oyster, perhaps shortly after a meal of tainted shellfish. No doubt this extraordinary specimen now rests, yoke-like, between the pendulous breasts of a society maiden on the wrong side of 40.

While owners of such gems may genuinely believe them to be priceless, they surface most often from the bowels of unscrupulous dealers' collections, always with an inflated appraisal claiming them to be more valuable than the British Crown Jewels.

This was the case with the infamous Life and Pride of America Star Sapphire, which featured in many news reports of 1985 and 1986 (Hughes, 1987b). In a story that would warm the heart of even the most jaded observer, one Roy Whetstine claimed to have bought the 1905-ct stone for $10 at the Tucson gem show. But things turned dour when a reporter discovered that one L.A. Ward of Fallbrook, CA, who appraised it at the whopping price of $1200/ct, had appraised another stone of the exact same weight several years before Whetstine said he found it. Photographs of the "gem" revealed an opaque corundum lump that would be put to better use dressing grinding wheels than windows at Tiffany.
