Stunning Large Flawless Natural Tanzanite, Diamond and 18 Carat Gold Necklace from London’s Hatton Garden: Members save £4,400

This dazzling precious pendant features a rare, flawless, velvety-blue tanzanite stone of the finest colour and quality, surrounded by brilliant-cut diamonds. When we say ‘flawless’ we mean it—the quality of this 8.59-carat stone is out of this world, even above AAA rank.

The fabulous large tanzanite stone was mined in the foothills of Mount Kiliminjaro, in the renowned ‘D Block’ wherre the best tanzanites are found. It was given an oval brilliant cut to bring its beauty to life. It flashes blue, with hints of purple and bronze—and one can see why it is considered one of the most gorgeous gemstones to be mined in East Africa.

Large tanzanite gemstones are rare, and thus expensive. Blue tanzanite is also more valuable than a stone that tends to purple—but to bring out the blue colour means the gemstone cutting loss is higher: yet another reason why this pendant is so highly prized. The sweep of diamonds which encrust the setting to highlight the beautiful blue stone are round brilliant cut, white (F in colour) and VS in quality, together weighing 1.23 carats.

The setting is 18ct white gold, fully hallmarked in England, and this ravishing piece carries a gemstone certificate and insurance certificate at the full retail price, as well as a lifetime guarantee. RRP £10,500. CCUK £6,100.
