I have two Lorique tanzies, a ring and a pendant.
The ring is a great stone and I have actually been offered significantly more just for the stone (2 and a half carat AAA pear cut) than I paid for the entire ring. Valuation also gave the ring a very good write up.
The pendant was sold as an AA (1ct oval) infact considered to be a "near miss" for AAA on the valuation.
Depends on what you're after but I also received a Thomas Rae tanzie as a gift - I say this quietly but the stone and quality is as good as the Loriques at a much better price point. Hope this helps
