Estate Jewelry Pearls

Help needed in settling my mothers estate?
Me and my siblings were counting on a hefty inheritance. Ya see Mom had ALOT of gentlemen friends and it seemed like every week she would brag “oh so and so gave me a pearl necklace last night”. Well now that she’s gone we have searched her house top to bottom and NO jewelry what so ever. How can we find out if Mother had a safe deposit box?
Have you tried a blacklight?
