4.01 Carat Old Mine Rhombus Cut Diamond Ring

About the Item

A Rare 4.01 carats Old Mine Cut Diamond Ring The ring centres a beautiful and rare old-mine cut rhombus shaped diamond of 4.01 carats (ca. IJ/VS1). It is accented by marquise cut and round brilliant cut diamonds on the shoulders. The ring is made in platinum and signed Lucas. Ring size L (51), can be resized. Old mine cut diamonds such as this one, are extremely rare, and were called old-mine cut diamonds, because they were mined in the older mines of India (Golconda) and Brazil. This diamond has been cut most probably in the 17th-18th century, as it beautifully shows the diamond shaped cutting (a little imperfect, but still very well balanced). Famous and historic diamonds with this cut are Hortensia diamond, the Grand Mazarin, and other few. Early diamond cutters (today known as bruters) shaped old mine cut diamonds by following the octahedral shape of the diamond crystal, laboriously grinding two diamonds together to achieve the desired shape, and a diamond polisher then polished the facets. Due to the shape of the rough and because the diamonds were hand crafted, dimensions varied from stone to stone. This made every old mine cut diamond unique, or put poetically, have its own personality. Some confusion surrounds the term “old mine cut,” especially as the term has evolved over the years. It probably came into common use around the late 1800s, at a time when diamond production from Africa began to eclipse production from the “old mines” of Brazil and even older mines of India. “Old mine cut,” originally meant any “brilliant,” cut squarish shape, colorless or near-colorless diamonds that originated in Brazil or India. Then, as African mines began producing diamonds of higher color quality, the term old mine cut was applied to any diamond with exceptional color and one that had the older style cut. Eventually, old mine cut was applied only to squarish-shaped diamonds with faceting arrangements that were popular beginning in the early 1700s.
