Dr. Gary R. Hansen and his wife, Barbara, of G.R. Hansen Precious Stones, have donated a collection of Staffmultigemstone pavé jewelry to the Gemological Institute of America Museum Collection. The collection, purchased during one of the couple's trips to Switzerland, includes a maple- leaf necklace and earring suite; four butterfly brooches; and two pins, titled Bird of Paradise and Wild Roses, all either set with diamonds, tsavorite garnets, and/or sapphires. Each piece, produced in Austria within the last decade, is set in 18k blackened gold. One butterfly brooch features wings accented with two rose-cut diamonds, 38 round single-cut diamonds, 186 round pink sapphires, 164 round blue sapphires, and two tsavorite garnets for the eyes.
