Caroline's Jewelry with a Past is offering a platinum topped 18kt. yellow gold pierced and millegrained sparkly diamond and sapphire Edwardian era brooch c. 1910. This piece has a very geometric look to it. The center diamond is a round, old mine cut diamond set in a millegrained bezel. The stone is 0.10 carats. There are an additional twenty-six rose cut diamonds added for interest. Eighteen calibre cut sapphires create a pyramid effect at each end of the brooch. The central diamond is surrounded by sixteen square cut sapphires. All of the sapphires are a dark, rich blue. The entire mounting is millegrained and pierced exquisitely. No detail was left undone. A beautiful piece that is 2" overall in length and 1/2" wide (maximum). It has a safety clasp closure.

Since platinum was difficult to work, jewelry made with solid platinum was not readily available before the late 1870's when jewelers learned to fuse platinum foil to gold allowing the look of solid platinum. Around 1878, a patent for setting diamonds with platinum tipped prongs was issued. About 1890, gold items fully topped with platinum were produced. Millegraining is a finishing detail usually made on platinum jewelry in which the surface has been made to appear "beaded". Millegraining work can also produce knife edging, patterns, and other design details. It is generally used with diamonds to give added sparkle without detracting from the stones.
The closure style was used on European pieces as early as 1896, but not generally used in the US until about 1912.

The gold and platinum content of this piece has been tested using standard accepted testing methods, such as acid testing. The diamonds were measured for size using a standard jeweler's caliper. The diamonds were tested using a standard jeweler's diamond tester. The sapphires and diamonds were not removed from the piece for size or weight.
