Diamond jewelry is an ever-growing market, and fine jewelry remains a big part of life’s biggest celebrations—engagements, weddings, coronations, graduations, job promotions, and more. Jewelry is a fitting tribute to moments we want to revisit and remember forever. Here is Westlake’s guide to diamond jewelry brands that pioneered the market today:

Tiffany & Co.

Tiffany and Co is a luxury jewelry and specialty retailer, located and headquartered in Manhattan on fifth avenue. This brand is known particularly for diamond and sterling silver jewelry. Today, operated 326 stores globally. Today it is a household name, Tiffany and Co. remains America’s leading silversmith.

Originally called Tiffany & Young, Tiffany & Co. started as a stationery and fancy goods store in New York City in 1837. The name, which originally started as “Tiffany, Young, and Ellis”, changed to Tiffany & Company in 1853 when Charles Tiffany took control and established the company’s emphasis on selling fine jewelry.

The brand showcases its more extravagant and rare pieces in its yearly Blue Book collection, a mail-order catalog that started in 1845. Some of the most famous pieces include the Return To Tiffany, Tiffany Key, and Tiffany Soleste and their signature engagement rings.

I've sold gold at Westlake Gold a couple times, and the experience has always been top notch. Unlike some less scrupulous precious metal buyers, Westlake will give you fair value for the metals you bring in. This is my go to and I highly recommend anyone to make this their first stop when selling gold or silver

Westlake Gold is the best in the area, it was recommended to me by a friend and it did not disappoint. Nikki was very helpful, very professional, considerate and nice. They are an honest business, have current equipment and pay a very fair price. Just to put it in a perspective, they paid me 5 times more than another place in Westlake, that keeps sending flyers. There was no hassle and their check cleared overnight. I will definitely use their services again.

Had a silver medallioin which Westlake Gold evaluated for authenticity using 3 different instruments. The daily silver strike price was updated continuously on the display board which took any guess work out of the discussion. Just previously I had the medallion appraised by another silver/gold shop which greatly undercut the price. I feel I got a fair price at Westlake Gold where I was offered 12% below the strike price. The other gold/silver shop offered me 29% below the strike---adios to them. I feel you will get a good evaluation of your asset and a fair deal at Westlake Gold.

This was my first time at this business selling my gold and I gotta say that Joel knows his stuff and he’s been in the business for a while. He treated me with respect and courtesy, and he gave me honestly the best pricing for a gold dealer of all of LA County and I’ve been in the business myself as well for a little bit so his pricing is extremely competitive. He explained the process very easily, tested all my pieces and gave me prompt payment. I’m going to be doing business with him more and bringing him a lot of more customers. I really appreciate him. :) 5/5 stars totally recommend Baron
