Introduction to Burmese Sapphires

Although it is rubies for which Burma (Myanmar) is famous, some of the world's finest blue sapphires are also mined in the Mogok area.

Introduction to Burmese Sapphires

Today the world gem trade recognizes the quality of Burmese sapphires, but this was not always the case. Edwin Streeter (1892) described Burmese sapphires as being overly dark. Unfortunately this error was later repeated by Max Bauer and others. G Herbert Smith wrote…

"While the Burma ruby is famed throughout the world as the finest of its kind the Burma sapphire has been ignominiously, but unjustly, dismissed as of poor quality. In actual fact nowhere in the world are such superb sapphires produced as in Burma."

- GF Herbert Smith, Gemstones, 1972

While this statement must be qualified by adding that the finest Kashmir sapphires are in a class by themselves, those from Burma are also magnificent. J Coggin Brown (1955) said this:

"It has been stated that Burmese sapphires as a whole are usually too dark for general approval, but this is quite incorrect; next to the Kashmir sapphires they are unsurpassed. Speaking generally, Ceylon sapphires are too light and Siamese sapphires too dark, and it is more than probable that many of the best 'Ceylon' stones first saw the light of day from the mountainsides of the Mogok Stone Tract."

- J. Coggin Brown, India's Mineral Wealth, 1955

Not all Burma sapphires are deep in color. The best display a rich, intense, slightly violetish blue, but some are quite light, similar to those from Sri Lanka. The key difference between Burma and Ceylon sapphires is saturation, with those from Burma possessing much more color in the stone. Color banding, so prominent in Ceylon stones, may be entirely absent in Burma sapphires.

Burmese Sapphires

Although rubies are found with much greater frequency at Mogok (rubies form about 80-90% of the total output), sapphires may reach larger sizes. Cut gems of over 100 carats are not unknown. Large fine star sapphires are also found at Mogok, in addition to star rubies. Near Kabaing (Khabine), at Kin, is located a mine famous for star sapphires.

The sapphires of Burma occur in intimate association with rubies in virtually all alluvial deposits throughout the Mogok area, but are found in quantity at only a few localities, particularly 8 miles (13 km) west of Mogok, near Kathé (Kathe). At Kyaungdwin, near Kathé, in 1926 a small pocket was discovered that yielded many thousand pounds' [sterling] worth of magnificent sapphires within a few weeks." (Halford-Watkins, 1935b)

An interview with U Thu Daw

Longtime Mogok gem dealer, U Thu Daw, a contemporary of ACD Pain (of painite fame), was interviewed by one of the authors (U Hla Win). The following are some of his edited comments on Burmese sapphires: U Hla Win: Were there any big sapphires found in the pre-World War II days? U Thu Daw: Yes, including some famous stones. U Kyauk Lon from Gwebin village found one and sold it to Albert Ramsay for one lakh of kyats [US$13,000]. [Ramsay later named the 958-ct giant the 'Gem of the Jungle'] UHW: Isn't he the one who was famous for star sapphires? UTD: Yes, he became famous because of his dealings in Mogok, although he did not have much money when he first arrived. UHW: Do you know of any other famous sapphires? UTD: Yes. U Shwe Hlaing of Zegyi found one which weighed over 100 carats after cutting. I saw it with my own eyes and it was quite beautiful. UHW: How much did it sell for? UTD: U Shwe Hlaing did not sell it in Mogok. After attempting to sell the gem in England, it was eventually sold to U Shwe Kin, owner of Rangoon's Kwan Louk Hotel, for under one lakh kyats. U Shwe Kin reportedly later sold it in Hong Kong. Figure 2. U Thu Daw of Mogok with his microscope formerly owned by ACD Pain. Photo: U Khin Mg Win UHW: Any other sapphires? UTD: Of course. U Kan from Ze Haung (Old Market) had one which weighed 1450 cts. U Shwe Kin also bought this one, for 70,000 kyats. But this time he wasn't so lucky. I think he cut it on a Saturday. U Shwe Kin's brother took it to Hong Kong. He was killed in a train wreck there and the stone lost. It was a fine sapphire and might have fetched 10,000 kyats. UHW: Were there any famous sapphires in the post-war period? UTD: I did not notice much. The famous sapphire mines are Loke Khet (Kaday-kadar), Chaunggyi (north of Mogok) and Lay Thar Taung. At Lay Thar Taung, the brothers, U Thein and U Ba Thaw, made a successful sapphire mine. There were so many sapphires mined that they had to be moved by horses. Those brothers were so kind-hearted that those who came to buy sapphire were sold bucketfuls. Many got rich because of those brothers. UHW: Were the sapphires of good quality? UTD: They were. Lay Thar Taung sapphires are famous in Mogok.

According to Halford-Watkins (1935b), the majority of fine sapphires were derived from the area between Ingaung and Gwebin. Sapphires have also been found near Bernardmyo: [1]

"Bernardmyo itself at one time produced large quantities of sapphires, many of which were of magnificent colour and quality, though a number were of a peculiar indigo shade, which appeared either very dark or an objectionable greenish tint by artificial light. During an extensive native mining rush to Bernardmyo in 1913 a number of these stones were placed on the London market.

Many of the stones found in this area were coated with a thin skin of almost opaque indigo colour which, on being ground off, revealed a centre sometimes of a fine gem quality, but in many cases of greenish shade. The method of occurrence was different from that anywhere else as the majority of stones were taken from a hard black iron-cemented conglomerate, which was found layers a few inches thick, often only a few feet below the surface. This area now appears to be exhausted, and little mining is carried on there to-day except for peridots, which are abundant.

Another isolated local deposit which has produced some fine sapphires occurs at Chaungyi, four miles north of Mogok, and about a thousand feet higher. "

- J.F. Halford-Watkins, 1935b

Other than blue, sapphires also occur in violet, purple, colorless and yellow colors at Mogok. The violet and purple stones may be fine; yellows tend to be on the light side and are not common. Green sapphires are known, but rare.

Rough Orientation

Orientation of sapphires from Mogok is important. While stones from localities such as Kyauk Pyat That retain their rich blue hue in various orientations, those from Chaunggyi and Painpyit take on a greenish tint when the c axis is not exactly perpendicular to the table. Many Mogok dealers attribute this phenomena to invisible black silk," and pay strict attention to locality when buying sapphire rough (U Hla Win, pers. comm., 2 Sept., 1994).

Famous Burmese Sapphires

SM Tagore in his classic work, Mani-Málá (1879, 1881), describes several celebrated sapphires. One of these was a fabulous stone of 951 cts, and was seen by an English ambassador to the Court of Ava (Burma). Tagore also mentions a curious custom among the Hindus of India. They were said to have a prejudice against sapphires, believing the blue gem to be the bringer of misfortune.

"In consequence of this notion, some of them would invariably keep a stone on trial for several days before they would make final settlement with the sellers. Hence, perhaps, the paucity in the numbers of Sapphires in their possession."

- SM Tagore, Mani-Málá, 1879

One magnificent Gwebin gem was scratched up just below the grass in 1929 by miners preparing a site for digging. Found by U Kyauk Lon (U Hla Win, pers. comm., May 2, 1994), it was a water-worn, doubly-truncated pyramid weighing an incredible 958 cts. Purchased for $13,000 by Albert Ramsay, who dubbed it the Gem of the Jungle, the rough produced nine fine cut stones, weighing 66.53, 20.11, 19.19, 13.15, 12.29, 11.39, 11.18, 5.57, and 4.39 cts. All stones were personally cut by Ramsay and were said to be of exceptional color. A marvelous account of the purchase and cutting of the Gem of the Jungle was published in the Saturday Evening Post in 1934 (Ramsay and Sparkes, 1934).

About 1967, a 12.6-kg (63,000 ct) crystal surfaced at Mogok. Today this sapphire colossus is on display at the Myanma Gems Enterprise (MGE) office. Like virtually all giant specimens, it is far from gem quality. In order to see if something of gem quality might be lurking within, MGE staff disemboweled it with drill and saw. Alas, the interior was just as opaque as the skin (see Figure 4). While this piece is billed by MGE as the world's largest sapphire crystal," in fact a number of much larger specimens are known, including a 40.3 kg crystal from Sri Lanka which contains gemmy portions (see Table 2).

On Feb. 22, 1994, a large sapphire of 502 cts was unearthed at Khabine, about 2.4 kms from Gwebin. The crystal is a single pyramid of rich blue color, and slightly silky (see Figure 6).

Table 1 is an admittedly weak attempt to catalog some of the more famous Burmese sapphires. Criteria for being listed includes titled specimens, specimens large or fine enough to merit mention in newspaper/magazine articles, and those which have set auction records. Unfortunately, due to the secretive nature of the gem business, many fine specimens have never been publicly described. The authors would love to hear from readers with additional information.

Notes

1. The plateau of Bernardmyo was chosen by the first British expedition to Mogok as a suitable place for a sanitarium for British troops. It was thought that the climate was more suitable for Europeans and that eventually the place would develop into the Simla of Burma. Bernardmyo was christened after the first British Chief Commissioner of Upper Burma, Sir Charles Bernard (GS Streeter, 1887, 1889). [return to article  ]
