I have a 72 points of color change garnet which I want to make into a ring with a halo. looking for petite diamond halo around the pear and half way on the band in 14k white gold. I don''t mind if it is an existing mount for needs to be custom. The exact mm''s of the pear are 6.27x 4.62 x 3.15. What is a price range I can expect to pay? I''ve done some online research but i''ve seen everything from $100- $2000 for similar settings. What might be a good starting point when approaching a jeweler?
