Embodiment 1

[0031] A processing method for adding luster to freshwater pearls, comprising the steps of:

[0032] S1 cleaning the selected freshwater pearls to obtain the first pearl embryo;

[0033] The cleaning solution used in the cleaning in step S1 is selected from anhydrous methanol, deionized water, manganese sulfate hydrate, sodium alkylsulfonate, disodium edetate, methacrylate-2-aminoethyl ester salt salt, ammonia solution, and reverse osmosis scale and corrosion inhibitors to prepare multiple treatment solutions; the types of the treatment solutions are five, which are the first to fifth treatment solutions, and the obtained first The selected freshwater pearls are sequentially soaked and cleaned in the fifth treatment solution to obtain the first pearl blank.

[0034] The first treatment liquid includes the following components: 950 parts of anhydrous methanol, 6 parts of manganese sulfate hydrate, and 6 parts of sodium alkylsulfonate; 35° C., soaking time for 50 hours.

Abstract

The invention discloses a processing method for brightening fresh water pearls. The processing method comprises the following steps of S1, cleaning selected fresh water pearls to obtain a first pearl blank; S2, the first pearl blank in the step S1 being alternately irradiated by a xenon lamp and a fluorescent lamp at the same time according to the sequence of soaking and cleaning in sequence to obtain a second pearl blank; and S3, intensifying the second pearl blank material, and continuously radiating the second pearl blank material by adopting an X-ray source to obtain a finished product pearl of a cold light gray system. According to the pearl brightening method, soaking treatment of pearl brightening is completed in sequence by using multiple treatment solutions, and the gloss grade of pearls is remarkably improved. A xenon lamp and a fluorescent lamp are used for alternately irradiating the first pearl blank, and finally the pearl color is made to be cold gray through X rays; a market value of the light-color pearl is improved.

Description

technical field [0001] The invention relates to a processing method for freshwater pearls, in particular to a processing method for adding luster to freshwater pearls. Background technique [0002] Most of the freshwater pearls currently on the market are white pearls with bluish-yellow skin, which have a single color, dull color, and poor gloss durability. Pearl ornaments processed with white pearls with bluish-yellow skin are not liked by young people, and the market price is low. [0003] Luminescent gray pearls are a more popular pearl color in recent years. Jewelry processed with pearls in this color is more high-end and fashionable, and is popular among young people. However, the natural luminescent gray pearls of freshwater pearls are very rare and expensive. Contents of the invention [0004] The purpose of the present invention is to provide a method for enhancing and processing ordinary light-colored freshwater pearls into natural cold-light gray pearls, which c...
