The Adamas

Antique reddish gold ring with 0,25ct old cut diamond solitaire, around 1890

"With the highest honors is he endowed, the adamas, the unbreakable hard diamond, whose fire and brilliance seem incomparable, whose clarity that of water, and whose durability almost unlimited." With these exuberant words, a popular non-fiction book of the first half of the 20th century describes the king of gemstones. Diamonds were popular at all times, but it was not until the discovery of new, productive deposits in South Africa in 1867 that a veritable boom in the hardest of all earthly minerals began. From the years around 1890, engagement rings with diamond solitaires came into fashion - and have remained so to this day. The present diamond ring, which came to us from Italy, also dates from this time - the last decade of the 19th century. In its center, it presents a brilliant-cut diamond in the historic old cut, the so-called "Old Europan Cut". The diamond has a weight of about a quarter of a carat and is held by a fine chaton, which develops seamlessly from the band. The gem is crafted of warm light reddish gold and comes in its original case.
