Fretboard inlays on 2009 57 reissue

I'd appreciate anyone's help with advise on what inlays Gibson used in 2009 on a 57 gold top. I need to replace one- No rounded corners, but looks like maybe the ones at Stew Mac might have rounded corners, and I don't believe the ones used in 2009 are mother of pearl either. From what I understand Gibson has changed material and shapes quite often so wondering if anyone knows for sure what was being used on 2009s at the custom shop? Thanks in advance for any help.
