Check out this versatile ring set; it includes 5 different gem colors to coordinate with your look or match your mood. Featuring the gem colors:  Clear, Pink, Purple, Black and Vitrail Medium, each set has internally threaded gems and a compatible ring.

The below measurements are approximate:

• Each gem is 6mm in diameter with M1.6 (10g) threading
• The gems have a rise of of 4.2mm from the surface of the ring, and a 6mm total rise 
• The band measures 2.5mm wide and is 1.7mm thick

While testing the threading on each gem, we found that they were very tight when they were initially screwed in.  However, using a cloth to pad the gems' prongs, we were able to thread each solitaire gem flush with the ring.
