Coloured & Fancy Diamonds: Unleashing the Brilliance
Coloured diamonds, often referred to as fancy diamonds, are incredibly rare, with only one in 10,000 diamonds having a desirable colour. The spotlight of the market shines brightly on colours such as blue, red, pink, and green. These rare and vibrantly coloured fancy diamonds represent an outstanding investment opportunity.
In recent years, fancy diamonds have become a coveted choice for jewellery investments and have shown remarkable returns. In particular, the CTF Pink Star, an enchanting pink diamond, garnered global attention as the most expensive gemstone ever sold, fetching a staggering $71.2 million at a Hong Kong auction in 2017. The combined allure of rarity and beauty makes fancy diamonds a highly desirable choice for collectors and investors alike.
Rare Vintage Rings: Preserving History with Style
Investing in vintage jewelry is on the rise, driving up its value. According to Art Market Research, vintage jewelry prices have risen 80% in the past decade, offering lucrative investment opportunities.
Within vintage rings, Art Deco jewelry is a standout category. Originating in France from 1920 to 1930, these pieces capture the essence of a unique era. The pre-World War I Art Deco era is particularly valuable. However, other factors beyond the era can influence the price of vintage rings. When considering a rare vintage diamond ring, investors pay attention to the 4 Cs: carat, clarity, color, and cut, as they have a significant impact on its value. For example, a 4.29 carat diamond with VS2 clarity and K colour set in platinum may command a price of $63,000.
