Diamond, Platinum Earrings 4674AP

Diamonds with this cut possess a squarish girdle with gently rounded corners. Old mine cut diamonds have a high crown, a small table, and a large, flat culet. They are similar to today’s cushion cut. The old mine cut dates to the 1700s and was most prevalent during the Georgian and Victorian eras.

The element platinum derives its name from the Spanish Platina del Pinto which translates to ‘little silver from the Pinto’ (said to be a river near Popayan, Columbia in which alluvial platinum was first found by the Spanish Conquistadors). Its white metallic luster leaves little doubt as to why the Spanish chose the name. Platinum belongs to a group of elements, fittingly called the platinum group of metals. Apart from platinum the group comprises Osmium, Iridium, Palladium, Rhodium and Ruthenium. Platinum is often found as natural alloys containing one or more of these other elements and it wasn’t until 1804 that all but one of the elements were isolated and named. Platinum is malleable, ductile and very strong. In addition, it does not tarnish and it doesn’t corrode making it a highly prized metal and extremely suitable for the manufacture of fine jewelry.

Authenticity, antiquity, decorative periods, vintages and or circa dating are determined to the best of our ability based on materials incorporated, methods of manufacture, design, hallmarks and signatures, lapidary techniques, technological developments and consultation of our extensive reference library and materials. Dating and period attributions are not an exact science as decorative periods frequently overlap and borrow influences from one another.
Some of our pieces are mounted in a way that makes it difficult to determine a precise stone’s grading. Diamonds and colored gemstones that cannot be removed from their vintage settings without harm to the piece are evaluated in their mountings using industry-standard measurements and formulas. Jewelry descriptions and all carat weights stated represent approximates. Mounted stone(s) is/are graded only insofar as mounting permits observation. All diamonds shown on our website are natural, untreated diamonds.
Most colored gemstones (i.e. rubies, sapphires, and emeralds) are commonly treated to enhance colour or clarity. This has not been researched for this specific item.
We cannot guarantee that the color you see matches the item color, as the display of color depends, in part, upon the type of computer monitor used to observe the image.
