Gold is a rare metallic element with the chemical symbol, AU, for the Latin word "Aurum", meaning Glowing Dawn
All our jewelry is made from pure karated gold, and hallmarked accordingly.  Our designer pieces are made exclusively from recycled gold purchased from our local refinery.   

         

The properties of Gold are unique to all other metals.

  • Pure gold does not tarnish, rust or corrode.
  • Gold can be melted and shaped into many forms.
  •  Pure gold has a natural warm yellow color, it is colored by other metals added to it. All other precious metals are silver or grey.
  • Gold can be alloyed with several other metals to increase its strength. 
  • Gold allows for different type of finishes; including, highly polished, satin, matte, hammered, diamond-cut and filigree.
  • Gold is described in terms of karatage to indicate the pure gold content of a particular item.
Karatage describes the parts of pure gold per thousand; for example, if an item is stamped (hallmarked)
  •  750 is measure for 18k gold having 750 parts of gold per thousand, 75% pure gold and 25% alloy (another metal)
  • 585 a measure for 14k gold, 58.5 % of pure gold
  • 24k gold must contain a minimum of 99.0% gold

All jewelry should be hallmarked, or called 'fineness mark' with a stamp to indicate the value of the item and the percentage of the precious metal versus the alloy.

Gold items can be produced in a range of colors including, white, yellow, red, green, blue, black and purple. The variations are achieved by mixing pure gold with other metals.

  • White gold is produced by alloying pure gold with white metals; nickel, silver, palladium and zinc. Nickel should not be used for jewelry purposes because it causes allergies when worn on skin.
  • Rose gold is produced by alloying pure gold with raising the ratio of copper to silver.
  • Green gold is made by adding a combination of silver, palladium and copper.

Variations in color also affect the properties of gold hardness and strength due to the different mix of alloy.

"This store has a very pleasant environment and Jeff and Janet are both kind, wonderful people. I used Jeff a few times for appraisals and he was very thorough and was happy to answer lots of questions. He uses scientific methods and tests rather than going solely by appearance as some jewelers will try to do, and his expertise is well respected. On one occasion, he even went out of his way to help expedite a deal for me. He has my highest recommendation. Suzanne T., San Rafael, CA

“Jeff is an incredible gemologist who knows everything there is to know about gem stones. He is a true professional and can be trusted. The quality of their work is impeccible and always consistent.

Delicate and perfectly crafted. Packing was very secure and shipping was quick. I would not hesitate to purchase from Deleuse again! Michele, New Jersey

“Janet and Jeff designed and crafted our wedding rings and did a great job. They worked with existing diamonds we had in an antique ruby cocktail ring, added the sapphire stone and made a beautiful pendant with the ruby. In addition, they designed earrings for our daughters. All are still in great shape today. They are easy to work with and very reliable and trustworthy.” Peg M., San Anselmo
