These two opals are being set for my wedding. The white gold one is for me, and the yellow gold is a gift for my best friend who happens to have a thing for dragons. Both are 18K, and are being made by a wonderful custom jeweller, Pawel. Sorry for the blurry photo on the yellow gold one - it''s the best I have at the moment. The pieces are not quite finished yet - there remains some polishing on the white one and neither stone is set in. The opals really are much nicer than they appear in the photos as well.
