The modern diamond engagement ring as we know it today was popularized by De Beers, a diamond mining company. In the late 1930s, De Beers launched the famous “A Diamond is Forever” advertising campaign, which promoted the concept of diamond engagement rings as a symbol of eternal love. The campaign was a huge success, and diamond engagement rings quickly became a popular way to propose.

Today, diamond engagement rings are a beloved symbol of love and commitment all around the world. While the traditional style of diamond engagement ring has remained popular, there are now many different styles and designs available. Whether you opt for a classic solitaire ring or something more unique, a diamond engagement ring is a timeless symbol of your love and devotion.

If you’re shopping for a diamond engagement ring, you’ve probably heard of the 4Cs: cut, clarity, color, and carat weight. These are the four factors used to determine the value of a diamond and understanding them is key to finding the right stone for your special someone.

The Cut of a diamond is the most important factor when it comes to its sparkle and brilliance. A well-cut diamond will reflect light in a beautiful way, making it appear brighter and more dazzling. A poorly cut diamond, on the other hand, will look dull and lifeless. When shopping for a diamond, look for one that has a high cut grade, such as an Ideal or Excellent.

Clarity is the measure of how many inclusions, or flaws, are present in the diamond. The fewer the inclusions, the higher the clarity. When shopping for a diamond, look for one that has a clarity grade of VS2 or higher. The Color of a diamond is another factor that affects its value. Diamonds range in color from colorless to yellow, with colorless diamonds being the most valuable. If you’re looking for a truly dazzling stone, look for a diamond that is graded D, E, or F on the color scale.

The Carat Weight of a diamond is the measure of its size. The greater the carat weight, the larger the diamond, and the more expensive it will be. However, it’s important to remember that two diamonds of the same carat weight can look very different depending on their cut and clarity.

Understanding the 4Cs of diamonds is essential if you want to find the perfect stone for your engagement ring. By taking the time to learn about each factor, you’ll be able to find a diamond that is both beautiful and valuable.

Joel took time and patiently explained the value of my jewelry and how he calculated it. I believe I got a good, honest deal and I would highly recommend him.

I could not have been more pleased and satisfied with Joel at Westlake Gold. If you have spare jewelry and gold that you want to get top dollar for, this is the only place that you need to go. Do not go to downtown LA. Do not go to any jewelry store and especially do not go to a pawn shop! Joel is the only man that you need to see. He is professional, kind, and as sincere and honest as they come. He has a low overhead for his business and he is without question going to give you the best possible price for your valuables. I didn’t even know that some pieces that I had were worth more than I had expected… but Joel being as honest and sincere as they come made sure that I had what I needed and did with a gracious understanding and very friendly demeanor. After leaving this place, I was both impressed and so happy to see that there are still people out there that do care about others. Do not waste your time and go anywhere else… this is the man to see!!!

The team at Westlake Gold was both kind and professional. Joel is very knowledgeable and fair - and I really enjoyed working with him on the sale of some estate jewelry. I highly recommend!

*Respectful, surprisingly great appraisal, very safe and honest.* Joel meets his customers in a clean and neat office inside of an office building, instead of many others in the area. This allows me to feel more comfortable to start with. He was very respectful, friendly, and courteous. The best part comes with the pricing. This was not my first time releasing old gold and jewelry, and I received way more than I thought I would have given my past experience with other jewelry buyers. Thank you, Joel. Wish I had met you in the past, but sure am happy I do now.

If you are looking for an honest appraisal and fair deal, this is the place to go! I walked in with what I thought was seven 1oz Canadian silver dollars worth $25 each, turns out they were 1oz Canadian platinum coins with worth $1,000+ each!! He operated with 100% integrity and patience with me. He took the time to educate me on coins. I will defiantly return!

I bought two rings from Joel and was blown away by the experience. He is extremely honest, professional, and knowledgeable. He normally doesn't make jewelry sales to walk in customers, but just so happened to have exactly what we were looking for. And he even arranged to have our rings resized and polished. They are beautiful and exactly what we wanted.
