It ll make the moment stand out even more if you use your creativity and romance to give them the diamond anniversary ring. If not direct metal then agates are the preferred stones to use for seal rings. The last one that I came across was selling for around $300 US, was an English ring about 250 years old and the seal was made from carnelian.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut are almost as good as ideal. While nature determines the color and clarity of a stone, diamond cut is dependent solely upon the skill of the cutter. Premium cut diamonds may be close to the ideal cut proportions and look just identical. Most people cannot distinguish between the two. However, there is a slight difference in quality and reduction in price over ideal cut diamonds.
Color J is the last letter that constitutes the near colorless range. Presence of yellow or brown tint may be noticeable to a non-professional. When mounted in yellow gold setting, such diamonds will appear colorless to the most people. J color diamond is a good buy for budget conscious.
Clarity Diamonds of VS1 clarity are very slightly included grade one. VS1 diamonds with tiny inclusions that are difficult to locate. Only a trained eye looking through a 10X loupe can pinpoint the inclusions in this category. The inclusions are nearly impossible to see with the naked eye. Excellent buy by all means.
