If You Are Purchasing A Diamond This Holiday Season Make Sure You Know These Questions

J&M Jewelry™

With the holidays right around the corner there’s a good chance you might be in the market for a diamond? A few very important questions to make sure you fully understand are below:

1) Am I buying a genuine earth mined diamond or is it a synthetic diamond made in a lab that is being marketed as a real diamond? Genuine earth mined diamonds have a limited supply. Since synthetic diamonds have an unlimited supply simple economics tells us synthetic diamonds don’t have the same value as a genuine diamond.

2) Is my genuine diamond GIA Certified? This is very important and be sure your diamond has a GIA Diamond Grading Report and not just an appraisal performed by a GIA Graduate Gemologist. Certifications and appraisals are not the same thing.

3) Has my diamond been enhanced? There are a lot of enhancements that genuine diamonds can go through including laser drilling, fracture filling, and acid washing just to name a few. Purchasing a GIA Certified Diamond will ensure your diamond is free from enhancements and treatments.

4) Are you purchasing your diamond in a retail setting? If so, you are paying too much. Diamonds are a commodity and their pricing is based off current market pricing. Retailers are charging far above these market values so they can sustain their high over head business models. Many times they might call themselves a wholesaler but it’s just a marketing term they are using.

At J&M Jewelry we specialize in genuine earth mined diamonds that are GIA Certified and free of enhancements or treatments. We are TRUE wholesalers not just using that term for marketing. Our pricing is based on the current market value and we disclose that information to our customers up front at the point of sale. Unlike retail jewelers that are selling synthetic diamonds and non GIA Certified Diamonds, we pride ourselves on educating our customers and making sure they are fully aware of the details of their purchase. We guarantee we can provide the highest quality diamonds and jewelry that is made in America at an unbeatable price. Give us a call this holiday season. We’d love to earn your business!


Fancy Yellow Diamonds & Their Color Scale

J&M Jewelry™

Unlike white diamonds Fancy Yellow Diamonds have their own grading scale that classifies these colored diamonds into 4 categories based on their natural hue. The 4 Fancy Yellow categories are Light Fancy Yellow, Fancy Yellow, Fancy Intense Yellow, & Fancy Vivid Yellow. These color saturations are created by the earth during the time the diamond was created. Yellow diamonds get their color due to the existence of nitrogen molecules which absorb blue light. Buying fancy colored yellow diamonds that are GIA certified is the only way to ensure you are receiving a genuine natural fancy yellow diamond and not a lower color diamond on the white diamond scale. White diamonds are graded on the color scale ranging from D - Z. The diamonds nearest to D are considered to be colorless or near colorless. The closer the diamond color gets to Z the more present you will see tints of yellow and brown. Often times diamonds that display a faint tint of yellow and are considered “XYZ” diamonds on the white color scale are passed off as fancy yellow diamonds. In reality they are not fancy yellow diamonds and do not fall within the 4 categories mentioned above. Colored diamonds are more rare than white diamonds and buying a fancy colored diamond with a proper certification is the only way to ensure you are receiving the quality you think you are. At J&M Jewelry we only provide genuine fancy colored diamonds that are GIA certified.
