SUGARLOAF CUT GEMSTONES

 

Shown above is a recent, and might I add, rather rare sapphire and diamond ring that we've just added to our DIVINE FINDS JEWELRY SHOP

What's RARE about it? Well you might not realize on first glance that this sapphire has no facets ... you know .. those precise cuts you find in most diamonds and gemstones to make them sparkle. That's because this is a SUGARLOAF Sapphire, not faceted, but cut so that it has a super smooth and oval rounded finish that rises to a rounded peak in the center, a bit like, well, Mt. Sugarloaf in Australia:


But in this case, I'd have to say the ring is somewhat more beautiful. 

Sugarloaf gemstones are unusual in that they are cut, not for sparkle from facetting, but to bring out the natural beautiful colour of the gemstone. Is this something new? No, not at all. This type of cutting dates back to ancient times. Our ring above dates to the Art Deco period. A sugarloaf gemstone is essentially, a cabochon, but rather than being just rounded, they come to a gentle point like the top of a mountain. And boy, are they rare and valuable!



I did a bit of searching before I wrote this post. I googled "sugarloaf gemstones" on Google and it brought up only 7 photos. Only 3 of these were of sugarloaf gemstone rings and only one was a sapphire. So I slipped over to eBay. Results there weren't much better, and the prices floored me when it come to the genuine thing ie. a vintage sugarloaf gemstone of any appreciable size. Little wonder then, when we took our ring in for appraisal, it came back at nearly $12,000! Not only does our ring have 1.72cts of diamonds: that glorious sugarloaf sapphire is 12.9 grams of pure gemstone, cut to bring out its natural beautiful rich blue and letting the diamonds around it provide sparkle.

According to the Natural Sapphire Company website, "Sugarloaf sapphires are in high demand and difficult to find. Cabochon cut sapphires are normally heat treated, as are most sapphires these days.  A fine untreated cab is usually seen in antique estate jewelry. And, It is important that the color within the stone be evenly distributed with no color zoning.  Heavily zoned or included cabochon sapphires will cost a lot less than clean transparent cabs.  Large cabochons are very difficult to find and highly prized."

Our ring meets all those criteria. It is large, estate, not heat treated, has even colour distribution and  no colour zoning. For that person who wants a ring few others have or can get, our ring is worth acquiring. It's rare, art deco, valuable and positively beautiful. Be sure to slip over to DIVINE FINDS JEWELRY and to see more photos and learn more about it. If you want "special" and "unique" you're looking at it.
