Lab-Created Diamonds - Simulated Diamonds And Manufactured Diamonds Review

!±8± Lab-Created Diamonds - Simulated Diamonds And Manufactured Diamonds Review

There has been a great deal discussion about lab-created diamonds. Along with that talk, there is much misinformation and perplexity. The jewelry lover, who is interested in realizing the huge savings and aesthetic beauty that simulated diamonds offer, is often bewildered by the manufactured diamond industry jargon and available options. This article will categorically break it down in easy-to-understand terms so that anyone can make an intelligent decision when choosing a simulated diamond.

GEM MATERIALS: 99% of all lab-created diamonds sold worldwide are polycrystalline on a molecular level. The differences are fundamentally in the technical aspects of manufacturing, cutting, and polishing. Think of it this way--all coffeemakers are made of plastic, steel, and glass, the differences are how these materials are designed and implemented. Higher quality coffeemakers make a better tasting cup of coffee. Higher quality manufactured diamonds are in line with mined diamonds.

QUALITY VARIANCES: It seems like grade variations are made out to be a more complex lab-created diamond issue then it really is. Once boiled down, there are three primary grades of simulated diamonds--high, medium, and low. For the jewelry shopper it should be noted that the quality of setting goes hand-in-hand with the quality of the gemstone. Those that sell manufactured diamond jewelry off point-of-purchase displays in the costume jewelry sections of discount stores use low quality or scrap stones that are not gem quality, and have disco ball or murky look. Those that sell manufactured diamond jewelry on the TV shopping channels--which is generally with a sterling silver or a micro-thin layer of gold plated over silver (Vermeil [pronounced ver-may]) settings--use medium quality stones not of gem quality. Those that sell solid 14K gold or solid platinum settings, as a rule, use the highest gem-quality man made gemstones that replicate mined diamonds.

PRICING: Low grade stones are sold in bulk to costume jewelry makers and are often glued on electroplated settings. This jewelry is fine for children, where loss risk is high, and usually retails for less than per item. You will find medium grade stones primarily in sterling silver jewelry that sells for under 0 per item, settings and stones. Medium grade simulated diamonds can be distinguished by the naked eye as not being mined diamonds. High grade gemstone quality lab-created diamonds, undistinguishable by the naked eye from mined diamonds, are found mounted on settings of solid 14K gold and platinum. This is considered to be fine jewelry, with the best quality gemstones selling for under 0 per carat for the gemstones alone. Manufactured diamonds that sell for over 0 a carat are not higher quality than those that sell for between and 0 per carat.

RECOMMENDATIONS: If you are buying for someone that is likely to lose the jewelry, there is no reason to spend any more than you have to, and Wal-Mart will do just fine. On the clearance rack you can even pick up some jewelry for less than per item. If you buy simulated diamonds set in sterling silver, expect decent stones, but they will fool few into thinking they are mined diamonds. Also, your fingers are likely to turn green or black in response to a chemical reaction, not with the silver per se, but with the nickel/copper alloys in sterling silver. With any plated settings, gemstones are low to medium grade, and the plating will eventually chip off, particularly around the edges. When that happens, the nickel/copper alloys will be exposed, the setting will look like it came out of a gum ball machine, and your finger will generally turn green or black. It is just a matter of common sense, if you want simulated diamonds with mined-diamond qualities, they must be set in 14K solid gold. Jewelers who offer lab-created diamonds are not going spend on money on gold and not mount the highest quality stones, which would defeat the purpose of creating fine diamond-like jewelry and alienate customers.

How To Read Jewelry Marks

!±8± How To Read Jewelry Marks

The number markings on precious gold jewelry are a bit of confusion to lots of people. We are generally used to seeing a karat or silver mark like this: 10K, 14K, 18K, Sterling, etc. The numbers mean the same thing.

For 14k the number is technically 583 but most manufacturers adopted the European way and make 14k gold a tiny bit over 14k, so the mark is 585 in most 14k jewelry. 18K is marked 750. If the mark is valid and there is a makers mark also in the jewelry, the number means these items are 18k gold.

Here is where the numbers come from. Pure gold is called 24 karat. For 18k gold, there are 18 parts of pure gold mixed with other metals to make the metal suitable for use in jewelry. 24k is too soft alone to stand up or to hold stones well. 18 parts pure gold divided by 24, or 18/24 equals 750. That is where the number comes from. The jewelry is 75% pure gold, 750 parts gold with 250 parts other metals out of "1000" parts. It is easier to think of it as a percent which is pure gold in the recipe.

Sterling silver is marked 925. Sterling is 92.5% pure silver and the rest is other metal, generally copper.
What does it mean if the ring marked 14K PR? The 14K simply means it is 14K (Karat) gold and because of the K means it would have been made in either South East Asia or The United States. The PR marks are just the Maker or Store ID or even a design mark, and have no relevence to the Value.

The basic decimal formula to work out the quality of gold content is quite simple, as they are all measured in 'Parts per Thousand.' This means that 9ct gold is calculated like this: 9 (for 9ct) is divided by pure gold (24) and then multiplied by 1000 (for pure gold as a decimal). ie: 9/24*1000=375 That 375 is the decimal quality for 9ct gold and is sometimes shown with a decimal point in front - .375

The old Victorian standard of 15ct gold is calculated the same way - 15/24*1000 = 625 (Not quite the numbers you have on your jewelry. Dental gold is 16ct or 666 recurring. But you can also reverse this formula by starting with the decimal and working back. ie: 375/1000*24 = 9

In your case we can use 698/1000*24 = almost 17ct
I have a platinum engagement ring and found a wedding ring that I really like but the band is made of palladium. Is it safe to wear these two metals together without one damaging the other?

It will wear the softer metal OVER TIME but that could take many years. My Grandmothers wedding ring eventually wore away the band of her engagement ring but it took over 20 years to do.

Platinum and Palladium and quite good together but I would take the advice of your local friendly jeweler and have them check both rings. Sometimes the Platinum may be a lower grade in order to make it harder - so have that checked.
