In addition to the classic variation of a golden ring, there is also the beautiful variation of a platinum engagement ring to choose from. A platinum ring is on the one hand modern and on the other hand something special, because platinum looks quite exquisite. For the choice of your diamond color it makes a big difference whether you choose a yellow gold ring or a platinum ring. The reason for this is again the high reflexivity of diamonds. Unlike the yellow gold diamond ring, where you can easily choose a diamond of a lower color category such as J, K or even L, with a ring as platinum you have to choose a diamond of a higher color category. Here the money is well invested when you choose a diamond of category G, H, I or even F. The reason for this is that the bright, silver or platinum with the cold, colorless white of a diamond of the better color categories looks very noble, while a slight yellow tinge would be unfitting.
The best cut for platinum rings
While yellow golden rings radiate a certain warmth, platinum rings have an elegant and proud style. Here too, the right cut can on the one hand highlight the diamond and on the other hand emphasize the overall appearance of the ring. Since you should choose a diamond of a high color category for a platinum ring, you can choose one regardless of how it hides the color of the diamond. On the contrary, cuts that bring out the color of the diamond are ideal. Especially the Asscher-Cut is very popular in combination with a platinum ring, because the ring keeps its charisma. But also, an emerald cut looks much better on a platinum ring than on a yellow gold diamond ring. My choice here would definitely be an Asscher cut in combination with a diamond of color category F. Whether you choose a solitaire ring or attach several diamonds to the ring is your choice, but in my opinion platinum rings look better as solitaire rings.
Solitaire ring or several diamonds?
Again, your choice depends heavily on your budget, but keep the following in mind. If you decide against a solitaire ring, then make sure that regardless of whether you choose a yellow gold ring or a platinum ring, the central diamond should be the most colorless and the one with the highest carat. A 1.5 carat diamond of category E or F, can be perfectly combined with two 0.8-0.9 carat diamonds of category J or K. However, if a J diamond is mounted in the middle, accompanied by two E diamonds, its yellowish shimmer will be much more visible.
Color of the prongs
The same applies to the color of the prongs as to the material of the ring, as they will also be visible through the diamond. If you choose a yellow gold ring, your choice of prongs should also be gold. If you choose platinum as the material for your ring, then you can use white or metal prongs to highlight the diamond, as they will emphasize the diamond. However, the color of the prongs and that of the material should be similar so that the diamond can develop its full beauty. Another beautiful cut, which fits for platinum rings much better than for gold rings is the Cushion cut. The special feature of the Cushion Cut is that the diamond can also be held by golden prongs due to its cut. Normally I recommend to use the same material, but with a cushion-cut of an F diamond for example, I find the combination with golden prongs very successful.
Summary
In summary, when choosing the diamond color, you should pay attention to the material of the ring to invest your money properly. This will allow you to put more money into the size of the diamond. Also the material of the prongs plays a role, which should match the ring on the one hand and the diamond on the other hand. While with yellow gold rings you can save on the color quality of the diamond and make a good choice with an L diamond, with a platinum ring you should go for an E of the F diamonds. If you follow this advice, you cannot go wrong in your search for the perfect engagement ring.
