Princess Cut Diamond Ring: 3.47 carat with 1.05 tcw Trillion Cut Diamonds
This gorgeous princess cut diamond ring with trillion cut diamond side stones has a 3.47 carat square modified brilliant cut diamond in the center with 1.05 total carat weight of matched brilliant triangular (trillion cut) diamonds set in a stunning platinum mounting.
The princess cut diamond measures 8.97 x 8.68 x 5.69 mm so it has a length-to-width ratio of 1.03, which appears square to the eye. The GIA considers shapes square when the length-to-width ratio is 1.05 or less. The princess cut diamond has a 65.6% depth percentage and a 69% table percentage. For princess shape diamonds, we suggest a depth of 58-76% and table of 58-77% with smaller percentages generally producing bigger size for the carat weight and better cut.
The princess diamond is the second most popular diamond shape but is one of the most complicated shapes to set. The corners of the princess diamond come to points and are fragile. The prongs have to be carefully fashioned to hug the sides of the corners and gently curve over the top of the corners to secure the princess diamond in the platinum mounting.
The trillion diamonds measure 6.32 x 6.25 x 6.31 x 2.85 mm. The first three numbers are the point to point measurements while the fourth number is the depth of the diamond. The base of the trillion-cut side diamond needs to be a slightly smaller than the length of the adjacent center stone to allow the prongs holding the trillion-cut diamonds to fit inside the prongs holding the princess cut diamond. One or more of the trillion diamond corners is usually set with a V-shaped prong to provide stability and protection for the points of the diamonds without overwhelming the appearance with too much metal. This is a sign of excellent artistry.
The diamonds are set in a custom platinum mounting designed for these exact diamonds and the client's finger size. The finest three stone diamond rings are custom made so that the side diamonds fit snugly next to the center diamond and appear as non-stop diamonds across the finger when viewed from the top. The four-prong basket style head holding the center stone provides a durable and secure base for the diamonds.
The combination of a princess center diamond accompanied by trillion side diamonds is particularly attractive to those who like straight edges and points. Both diamond shapes are brilliant-cut so they have great brilliance and sparkle when properly cut.
We have seen many three stone mountings that fail to properly display and guard the princess and trillion diamonds. For example, many center diamonds are set too high, which looks odd and put the center stone at risk for damage. We also caution clients to properly match the center stone with the side stones. Diamonds in pre-set semi-mountings might not match the center stone you have in mind. You could be purchasing a beautiful G color center stone and putting it next to J colored side stones. Many poor quality trillion diamonds are set in semi-mounts in order to sell the diamonds. At the Diamond Source of Virginia, we carefully assess the entire layout to make sure the color and brilliance of the center stone matches the side stones.
