Would someone mind suggesting...

[all.of.the.above]

Where I would be able to find small - we''re talking suprise gemstone on a ring, small - blue sapphires? Heated or unheated is fine.
Thank you all a bunch!

For coloured stone melee, it''s best to have the jeweller/setter source the stone. It''s so small that the regular vendors don''t carry it because they can''t make any money selling it.
