Diamonds have long symbolized power, strength, and eternal love. Formed deep within the Earth under intense heat and pressure, they take billions of years to create. Their unparalleled hardness—ranking 10 on the Mohs scale—makes them resistant to scratches, while their optical brilliance has become the benchmark for fine jewelry.
Historical significance: Diamonds have adorned royal crowns and ceremonial artifacts for centuries. The Koh-i-Noor and the Hope Diamond are legendary examples of how these stones have shaped cultural narratives and politics.
-
Highest-priced diamond: The Pink Star, a 59.60-carat fancy vivid pink diamond, sold for $71.2 million at a Sotheby’s auction in Hong Kong in April 2017, setting a world record for any gemstone sold at auction.
-
Why it’s valuable: Exceptional clarity, precise cut, carat weight, and the rarity of fancy colors such as blue or pink.
-
Luxury houses featuring diamonds: Cartier, Graff, Tiffany & Co., Harry Winston.
Insight: Fewer than 1% of mined diamonds are considered flawless by GIA standards. These rare stones, often from mines in Botswana, South Africa, and Canada, are the pinnacle of luxury.
Ruby: The Gem of Passion
Ruby’s fiery hue and unmatched brilliance make it one of the most desired gemstones in high jewelry. Composed of corundum (aluminum oxide) with trace chromium, rubies are celebrated for their intense red color—known as "pigeon blood red"—especially when originating from Myanmar.
Cultural symbolism: In many cultures, rubies are believed to bring protection and good fortune. Ancient warriors even embedded rubies into their armor, believing the stone made them invincible.

Historical legacy: Sapphires have adorned the British crown jewels and symbolized wisdom and virtue. Princess Diana’s sapphire engagement ring, now worn by Princess Kate, cemented this gem’s status as an icon of royal jewelry.
