Important sapphire and diamond ring, Van Cleef & Arpels
- Van Cleef & Arpels
- Sapphire, diamonds, platinum
The few inclusions found by microscopic examination are consistent with those found in sapphires from the classic mines along the Mogok Gemstone Tract in Burma (Myanmar). Its attractive and saturated blue colour, poetically also referred to as 'royal blue', is due to a combination of well-balanced trace elements in the gemstone, which are typical and characteristic for fine sapphires from Mogok, Burma".
