If you are having trouble finding the exact profile, ensure the spelling is correct. IAFD sometimes merges profiles or lists performers under their most common alias. If "Jewel Diamante" yields limited results, check for common misspellings or check the "Similar Names" suggestions on the site.
If you meant a news or feature article about her (from a site like AVN or XBIZ), those are less common for performers of her era unless she was notable for awards or major industry events. You may need to check archives of adult industry news sites. jewel diamante iafd
