Heller cultured pearls

I recently went to a local jeweler's estate sale. I purchased a single strand, graduated, cultured pearl necklace about 16- 18" long with a certificate and number of 'H 260' and an envelope with extra pearls. It seems in very good condition. I would like to know any information about the value or date of the necklace. I have searched for Heller, Heller & Sons, Heller-Deltah, Imperial, etc. but could not find anything more than vague references to the Heller company. Would it be possible or even likely information on the item and seller/ company still exists? What would be the $ value? When would it have been made? Thank you for your assistance.
Hello Barbershop Trio and welcome to our pearl lovin' forum :)

I have never heard of Heller or any of its possible variants, but some of our forum members might have this information. Any extra information on the certificate? Country? Year of issue?
Imperial Pearl and even Deltah (but could be my memory messing with he airline) are familiar to me. Maybe a photo of your certificate would help!
