Diamonds That Tell Your Story

Marquise Diamond Blues

You have a beautiful marquise shaped diamond that you bought in the 80's and everyone tells you it isn't worth much.  How come?  It was more expensive 30 years ago than it is today.

Logic would dictate that if diamonds go up, that a diamond you bought a long time ago would be worth more today than when you bought it.  However, many diamonds don't fit that mold.  A round diamond is worth the most today.  30 years ago, practically any "fancy" shaped diamond (marquise, pear, oval, princess, etc.) was more expensive.  In the 80's, marquise shaped diamonds, like the one pictured to the right, was selling for 25% more than comparable round diamonds.  Today any diamond other than round is worth less than a comparable round diamond.  Fashion is the only logical explanation for rounds being so much more expensive today than any of the fancy shaped diamonds.  The internet makes it easy to compare the cost of one round diamond compared to another, but if you throw in the shape of the diamond, the calculation becomes more complex.

Your problem is that you want to sell that marquise diamond and nobody will give you a fair price, or what you consider is a fair price.  My suggestion:  take the best offer, because you'll have to wait 10 years for the fashion to change, and when it does, it doesn't mean that marquise shaped diamonds will be hot.
