I might have a pretty alternative, FMG sell Zircons in orange... however, it might be too orange like the hyacinth.
I bought a faceted zircon in champagne for my neice from FMG. It's the prettiest dark peachy orange with gold hues.Picture below:
However, now they have beads that you could make something with a lot of drops on gold beading wire. Kind of like an illusion necklace.
Links to some of the beads they have.. there are more.
