Black gems or diamonds8/23/2023 Rhodes embarked for South Africa to try his hand at cotton farming. Cecil Rhodes’ diamond empireĪnother boy - an enterprising seventeen-year-old Englishman named Cecil Rhodes - launched what many consider as the modern diamond industry. South Africa’s Premier Diamond Mine was an open-pit mine that opened in 1902 and operated for several decades. This stone, named the Star of South Africa, made its way to England where it was cut into a 47.69 ct pear-shaped stone and purchased by the Earl of Dudley. The pebble turned out to be a South African diamond weighing 83.50 cts, and Niekerk sold it for £11,200 (equivalent to US$56,000 at the time), almost 100 times the value of what he gave the shepherd. In exchange for the pebble, Niekerk gave the shepherd a horse, 10 oxen and 500 sheep, nearly all of his earthly goods. Eventually, he made his way to the same man who first noticed Erasmus Jacobs’ shiny rock-Schalk Van Niekerk. He first tried to trade the pebble for a place to sleep and then for breakfast. This discovery was treated with disbelief by most, and interest was lukewarm until 1869 when a shepherd found an enormous pebble. It is on display at the Kimberley Mine Museum. This enormous South African diamond was named Eureka, meaning “I have found it.”įound by 15-year-old Erasmus Jacobs, the 21.25 ct Eureka diamond was the first significant diamond discovered in South Africa. The stone passed through several hands before an amateur geologist identified it as a diamond weighing 21.25 carats (cts). A neighbor, Schalk Van Niekerk, intrigued by a particularly shiny pebble in the collection, offered to buy it from the boy’s mother, who then gave the pebble to Niekerk for free. The first significant South African diamond was found in 1866 by Erasmus Jacobs, a farmer’s son, who collected ‘pretty stones’ with his friends near the banks of the Orange River. Teenagers, farmers, a shepherd - these were the first to discover diamonds in Northern Cape Province, South Africa, and by doing so, give birth to the modern diamond industry. How South African Diamonds Changed Diamond HistoryĪre South African Diamonds Ethical Diamonds? Learn how Jacobs found the first South African diamond and how Rhodes built up a diamond empire. Two teenagers - Erasmus Jacobs and Cecil Rhodes - helped make this happen. Let’s view the following list for more details: Popular Gemstone Rings and their HardnessĬaution and care should always be taken when wearing any gemstone jewellery so that these timeless beauties can be passed on for a lifetime.South African diamonds gave birth to the modern diamond industry. Rings with Citrines, however, are not recommended to come into contact with heat as they can fracture. ![]() Some of the most popular types of gemstone jewellery products are Diamond Emerald Cut Rings and Radiant Cut Engagement Rings. These can often weaken the structure and make them more susceptible to scratching and even chipping – and some styles are not suitable for everyday wear, otherwise, S apphire Rings are excellent for everyday wearing because of the high hardness level. Emeralds for example are well documented as having many inclusions within the stone, that’s why a ring with emerald and diamonds is a special one. ![]() Whilst this scale is a guide to mineral hardness, it does not always factor in other elements of a gemstone’s structure when you are considering stones for day-to-day wear. This list will help you see the hardness of your favourite. We’ve taken a list of some of the most popular gemstones that are used in jewellery – you’ll find many of them in our Gemstone Rings collection and more products available on the Purely Diamonds website. The softest mineral that features on the scale is Talc at 1, and everyday objects of hardness such as pencil lead (1.5), finger nails (2.5) and window glass (5.5) can help you get a true value of the scale. The scale was created using the simple technique of one mineral’s ability to visibly scratch another. In 1812, Friedrich Mohs – famous geologist and mineralogist created a scale of mineral hardness grading from the softest (1) to the hardest (10), based on that information jewellers were searching for perfect the cut of a diamond. It’s often said that there’s nothing harder than a diamond, and we are often asked if a diamond is used to cut another diamond (the answer is yes)… But have you ever wondered how we know this? The answer is simple – the Mohs scale of hardness.
