Hi Dont know if Steve Green carries smooth brio's but he isdefinately the guy with the biggest faceted brio inventory I've everseen ! (incredible!!) His site address is www.briolettes.com. Hehas very cool matched pairs and singles in tons of different shapesand materials. He also has the most comprehensive web site when itcomes to answering the perplexing question of........'ok so I lovethese brios now how the heck do I set them?' He has done strengthand efficiency tests on several setting techniques and even suppliesyou with the correct conical cap in wax that fits the specific stoneyou pick.
In response to Marcy's request: A source for high quality facetedBRIOLETTES and SMOOTH DROPS is Rough and Ready Gems.
