According to diamond online (diamonds.net) reported on February 10th: Antwerp's HRD laboratory has identified and ranked the world's first fully diamond-made ring produced by the laboratory.
The "Diamond Ring" is produced by the Dutch Diamond Technology Company and is made of 155ct chemical vapor deposition (CVD) synthetic diamond transparent plate material. The finished diamond ring has a weight of 3.87ct, color E, and clarity of VVS2. The company named the diamond ring "Project D" to celebrate its 10th anniversary. It took a year for the Diamond Ring to be produced, with 133 aspects.

This "Project D Diamond Ring" is not the world's first "full" diamond ring. It is reported that in 2011, Swiss jeweler Shawish displayed a "full" diamond ring made of natural single crystal diamonds. The work refers to a ring weight of 150ct, worth 70 million US dollars, and it took a year to build. Here's a picture of the world's first "full diamond" ring:
