Welo Opal

GIA Report on Welo Ethiopia Opals. A new source of high-quality play-of-color opal was discovered in early 2008 in Welo Province, Ethiopia, about 500 km north of Addis Ababa. This deposit is geographically distinct from the Mezezo deposit in Shewa Province, which was discovered in the early 1990s (see, e.g., Spring 1994 Gem News, pp. 52–53).The cabochons showed good play-of-color (figure 1); the vast majority were white and transparent, but some had a bodycolor varying from light yellow to dark “chocolate” brown. Compared to Mezezo opals (e.g., J.-P. Gauthier et al., “L’opale d’Ethiopie: Gemmologie ordinaire et caractéristiques exceptionnelles,” Revue de Gemmologie a.f.g., No. 149, 2004, pp. 15–23), those from the new deposit generally appear much whiter. We noted all spectral colors in the play-of-color in our samples. Most of the cabochons were similar in appearance to opals from Australia or Brazil. However, many samples displayed a columnar structure of play-of-color opal within common opal (figure 2), as first described in material from Mezezo (again, see Gauthier et al., 2004). This feature is only very rarely observed in opals from sources outside Ethiopia.

The hydrostatic SG of the opals ranged from 1.80 to 2.10. This broad range is in part due to the high porosity of some samples, as revealed by a significant weight increase after immersion in water (up to 8%). Fluorescence varied from inert to moderate yellowish white to both long- and short-wave ultraviolet (UV) radiation. Samples that were inert displayed an unexpected greenish phosphorescence of moderate intensity. No luminescence was observed in the opals with a yellow-to-brown bodycolor, even the light ones; these darker bodycolors are probably due to the presence of iron, which quenches luminescence. The yellow-to-green luminescence is likely due to the presence of uranium (E. Gaillou et al., “The geochemistry of gem opals as evidence of their origin,” Ore Geology Reviews, Vol. 34, 2008, pp. 113–126). Fourier-transform Raman spectra were obtained for several samples using a Bruker RFS 100 spectrometer. All spectra were consistent with opal-CT, with Raman bands at about 1070, 780, 670, and 345 cm-1, and water-related bands at about 3200 and 2950 cm-1. 

Welo opal is found in volcanic rock, possibly a rhyolite. The rough samples we examined consisted of opal (either common or play-of-color) cementing fragments of the host rock. By contrast, opal from Mezezo fills cavities in rhyolite, forming nodules. Despite these differences, the fact that columnar structures are seen in opals from both deposits (but very rarely from elsewhere) seems to indicate similarities in the conditions of their formation.

Welcome to Konjo Opals, your source for the highest quality Ethiopian Opals, direct from the mines. We are a group of miners and master cutters that have been working with Welo Ethiopian Opals long before GIA recognized their discovery in 2008.

If your wondering what Konjo means it is the term the local miners of Welo Ethiopia use to refer to the best opals when they are found. Konjo = Best.

We currently attend many international gemstone shows specializing in Welo Ethiopian Opals, finished and rough. We take anywhere from 50,000 to 300,000 cts of finished opals and a minimum of 50 to 200 kilos of rough Welo Opals to shows. Some of the shows we attend as sellers are JCK Las Vegas, Hong Kong Gemstone Fair, Tucson Gemstone show. We are always at the opal mines weekly and every day new opals are being brought to our Ethiopia office by the miners that work with us.

All of the opals we display for sale here on Opal Auctions are hand selected for the rareness of patterns, top color play and rare sizes. Rest assured you are buying a true one of a kind opal when buying from us, we are not here to hype up our opals with fancy titles and terms like extreme or investment. We simply want to show you the high quality opals we can supply for unbeatable prices.

Our opals are graded on the following scale:

  • Bright 3/5 brightness
  • Very Bright 4-4.5/5 brightness
  • Brilliant 5/5 brightness

Welo蛋白石

GIA關於Welo埃塞俄比亞蛋白石的報導。 2008年初,在埃塞俄比亞的Welo省,亞的斯亞貝巴以北約500公里處發現了一種新的高質量彩色蛋白石。該礦床在地理上不同於Shewa省的Mezezo礦床,該礦床於20世紀90年代初被發現(參見,例如,1994年春季寶石新聞,第52-53頁)。凸圓形寶石表現出良好的色彩搭配(圖1) ;絕大多數是白色和透明的,但有些的體色從淺黃色到深色的“巧克力”棕色。與Mezezo蛋白石相比(例如,J.-P.Gauthier等人,“L'opale d'Ethiopie:Gemmologie ordinaireetcaractéristiquesexnenelnelles”,Revue de Gemmologie afg,No。149,2004,pp.15-23),來自新存款的那些通常看起來更白。我們注意到樣品中所有顏色的光譜顏色。大多數凸圓形寶石的外觀與澳大利亞或巴西的蛋白石相似。然而,許多樣品在普通蛋白石中顯示出彩色蛋白石的柱狀結構(圖2),如Mezezo的材料中所述(再次參見Gauthier等,2004)。在埃塞俄比亞以外的來源的蛋白石中很少觀察到這一特徵。

蛋白石的靜水SG範圍為1.80至2.10。這個寬範圍部分是由於一些樣品的高孔隙率,如浸入水中後顯著的重量增加(高達8%)所顯示的。熒光從惰性到中等黃白色到長波和短波紫外(UV)輻射都變化。惰性樣品顯示出中等強度的意外綠色磷光。在具有黃色至棕色體色的蛋白石中沒有觀察到發光,即使是淺色的也是如此;這些較暗的體色可能是由於鐵的存在,這會熄滅發光。黃色至綠色的發光可能是由於鈾的存在(E. Gaillou等人,“地球化學的寶石蛋白石作為其起源的證據”,Ore Geology Reviews,Vol.34,2008,pp.113- 126)。使用Bruker RFS 100光譜儀獲得幾個樣品的傅里葉變換拉曼光譜。所有光譜均與蛋白石-CT一致,拉曼譜帶約為1070,780,670和345 cm-1,水相關譜帶約為3200和2950 cm-1。

Welo蛋白石存在於火山岩中,可能是流紋岩。我們檢查的粗糙樣品由主岩的蛋白石(常見的或彩色的)固井碎片組成。相比之下,來自Mezezo的蛋白石填充流紋岩中的空腔,形成結節。儘管存在這些差異,但從兩種沉積物的蛋白石中看到柱狀結構(但很少來自其他地方)的事實似乎表明其形成條件的相似性。

歡迎來到Konjo Opals,您可以直接從礦山獲得最優質的埃塞俄比亞蛋白石。我們是一群礦工和大師,在GIA認可他們2008年的發現之前很久就與Welo Ethiopian Opals合作。

如果您想知道Konjo意味著什麼,那麼Welo埃塞俄比亞的當地礦工在找到它們時會用它們來指代最好的蛋白石。 Konjo =最好的。

我們目前參加許多國際寶石展,專門研究Welo埃塞俄比亞蛋白石,成品和粗糙。我們將採用50,000至300,000克拉的成品蛋白石和至少50至200公斤粗糙的Welo蛋白石來展示。我們作為賣家參加的一些展覽是JCK拉斯維加斯,香港寶石展,圖森寶石展。我們每週都在蛋白石礦場,每天都有新的蛋白石被與我們合作的礦工帶到我們的埃塞俄比亞辦事處。

我們在蛋白石拍賣會上出售的所有蛋白石都是手工挑選的,因為罕見的圖案,頂級色彩和稀有尺寸。請放心,當你從我們這裡購買時,你正在購買一種真正的蛋白石,我們不會用極端或投資這些花哨的標題和術語炒作我們的蛋白石。我們只是想向您展示我們可以以無與倫比的價格提供的高品質蛋白石。

我們的蛋白石按以下等級評分:

  • 明亮的3/5亮度
  • 非常明亮的4-4.5 / 5亮度
  • 輝煌的5/5亮度
