I was in the market of buying a big diamond 2.50carat plus went to all the pawn shops in the downtown and some of the diamond places in town.. diamond vault etc they had what i was looking for just not the right price . When i walked into sierra silver and gold buyers am not going to lie this place doesnt look like much! He informed me that they just started and i asked him if he had big diamonds for sale. He wrote down exactly what i wanted clairty,carat,color and what shape and called someone up put him on speaker and i got a great deal! Shipped it here and i paided for it ! He saved me 5 thousand off diamond vaults price! I am very pleased and would recommend anyone looking for diamonds to shop around youll be happy with his prices!
