Without actually seeing the paperweight and the signature, I'm almost positive it's an American glass collectible, made, as dated, in 1986. The glassmaker is Mark Cantor, who began his paperweight crafting with Steve Lundberg and Jim Lundberg in the 1970s. Cantor left to do his own work and was making his own unique abstract delicate feathery designs in the 1980s. Based on your photograph, this is one of his better pieces and clearly captures the light beautifully.
