Their attractive and saturated colour - poetically also referred to as 'Pigeon Blood Red' for part of these rubies - is due to a combination of well-balanced trace elements in these gemstones, characteristic for the finest rubies from Burma (Myanmar)...Assembling a matching selection of natural rubies from Burma of such a quality is rare and exceptional.';
