First of all, may I offer my congratulation to alice and complement you on your choice of the engagement ring and I have to say you have very good taste!
Despite being a girl who wears a 1.3 carat Colour: D, Clarity: Internally Flawless Tiffany engagement ring, objectively I'm going to have to disagree because I can categorically tell you that an engagement ring with a 1 carat D/IF 'Hope Diamond' diamond is ~$25,000 equivalent. Hope Diamond is a brand for diamonds cut by De Beers and IDENTICAL to De Beers diamonds in De Beers boutique. The only difference is that it's marketed separately by each buying jewellers, not by De Beers themselves.
Let's compare this price to my exact price on a 1 D/IF Tiffany's which is $38,000. So there is a $13,000 difference (I'm not going to say markup because Tiffany's diamonds come from their own semi-permafrost mine in Canada) enough to get another decent piece of Tiffany's jewellery. But surely everyone will agree with me that De Beers-cut diamonds are in no way inferior to Tiffany's and that it possesses just as much 'fire and brilliance.' The only difference superiority of Tiffany's I imagine is the setting which is often neglected but VERY important (even this is contentious from the objective sense). Actually I'm very surprised at the very little focus is on settings; what's the use of a diamond if there is no light - the most beautifully cut diamond will lose all its lustre in a poor setting!
So I'm going to say an ideal diamond is not expensive everywhere you go and Tiffany's DO rip you off! But there is good news; Tiffany's rip you off the least. A 1 D/IF De Beers is ~$45,000 (almost 100% markup on Hope Diamonds
) and Cartier 4-prong Solitaire is even more expensive than that.
Having said all of this, do I regret having a 1.3 D/IF Tiffany's? The answer is no. If you read my first ever post on this forum, I hinted to my fiancé that I want this and that's because other makes are too opulent (esp. Cartier) and does not fit with my dress style. This is not down to the diamond itself but the setting!

clanalois said:Regardless of the 4C's which Tiffany excels at, they sell diamonds with what are considered the most mathematically perfect/ideal cuts in the industry.
It is true that you can buy a diamond with the same 4C's as a Tiffany for thousands less. But mathematically and subjectively speaking, it will not possess the fire and brilliance of a Tiffany/ideal diamond if it does not have the ideal proportions, and you can easily see this when comparing. An ideal diamond is expensive no matter where you go.
