Another large diamond that had recently been sold at auction, was the 163-Carat D-Flawless "De Grisogono". The gemstone was set at the heart of an asymmetrical necklace adorned by suites of emeralds and other diamonds.



The design by De Grisogono founder Fawaz Gruosi, prioritizes the full visibility of the gemstones' magnificence, and therefore strives to hide all metal from its facade. This almost invisible way of craftsmanship truly brings out the vivid brilliance of both the record-breaking stone, and its accent gems.



Documentations have shown that this one-of-a-kind masterpiece required a schedule of over 1,700 hours to complete. Fourteen craftsmen contributed to the piece's creation, and this is evident in the complexity of its structure and beguiling appearance.

The De Grisogono diamond and its host necklace, sold for 33.7 million US dollars in Geneva under the efforts of Christie's auction house and its partners.


While this number may strike some as being incredibly extravagant for a single piece of jewelry, it was actually viewed as disappointing for many veterans in the diamond auction industry.



Both diamonds and emeralds are favorites here within the jewelry circles of Metro Manila, however specimens even a fifth of the De Grisogono's carat weight are an incredibly rare sight inside Philippine jewelry boutiques. Practicality and trend both play a part in the country's demand for diamonds. Normally, one to five carat sizes are the prime picks for most high society Filipinos, due to their high-movability translating to a better investment value.

Large diamond rough is very rare, so diamond cutters need to use an array of advanced instrumentation to scan and plot the best angles for cutting out the gem. The more weight preserved, the higher the returns will be for specimens such as this one. (Photography Credits to Christie's Auctions, and De Grisogono)
