Certified Diamonds Vs Non-Certified Diamonds
The term “certified diamonds” refers to polished diamonds that have undergone quality analysis, based on 4C, by a trusted gemological laboratory such as GIA (Gemological Institute of America).
Non-certified diamonds are very common in the marketplace and are simply those diamonds that have not been put through formal laboratory grading.
Certified diamonds aren’t inherently better than non-certified diamonds, but they tend to be higher-quality stones because the retailer has chosen them for their documented quality. Many times, certified diamonds are completely natural and have not undergone treatment.
Certified diamonds have been verified for quality, allowing consumers to purchase with confidence based on the attributes of the diamond. For small stones or accent stones, you might consider purchasing a non-certified diamond. In smaller diamonds, it can be difficult or near impossible to view quality characteristics with the naked eye. However, GIA does offer special testing for loose and mounted diamonds in smaller sizes.
Each certified-diamond have a unique ‘’certified’’. It is important for you not to confuse a ‘'Diamond Certificate’' with a ‘’Diamond Appraisal’’.
Diamond Certificate vs. Diamond Appraisal
There is a significant difference between the two documents. A diamond appraisal is typically prepared by the seller of the diamond to denote the estimated value for insurance purposes, while a diamond certificate is an unbiased analysis of the stone's quality prepared by a gemological laboratory.
