<p>[QUOTE=&quot;Curioser, post: 9771435, member: 13823&quot;]I am trying to estimate the weights of three princess cut diamonds in an engagement ring. I used to have a metal disk with graduated round holes in it that allowed me to estimate the weight of a set round diamond based on the diameter of the girdle. I would love a tool or online chart that does the same thing.&nbsp; But to get the job done today, I was hoping to find an estimator formula for other cuts of diamonds online. EVERYTHING I see requires the depth measurement which I can&#039;t do as the stones are mounted.&nbsp; I found one product for sale, a card that allows you to estimate carat weight for rounds, marquises and rectangular baguettes but not squares!</p><p><br /></p><p>Anyone know of an online estimator tool?&nbsp; If not, I will try to find a product that works with all the major facet styles and buy it.</p><p><br /></p><p>Thanks in advance![/QUOTE]</p><p><br /></p>
