Myntsølv var en gang en mer vanlig legering i USA. Det er nå ganske sjeldent og navnet forårsaker en del forvirring. Det tekniske “mynt sølv” legering er .900 sølv, eller 90% sølv og 10% kopper. Navnet “mynt sølv” is because metalsmiths historically made items from melted down scrap […]

Ikke-plettede legeringer er ganske nye på markedet. Argentium er ett merke, men det er andre tilgjengelige som ligner. Disse legeringene er et minimum av 92.5% sølv selv om noen vil ha litt høyere sølvinnhold. Resten består av kobber og tilsetning av grunnstoffet germanium. The germanium makes the alloy […]
Sterling is the jewelry quality standard in the United States and most world markets. Det er en legering av 92.5% sølv. De resterende 7.5% is usually copper though it is sometimes other metals such as nickel. The other metals in the alloy increase hardness so the material will be more durable. Alloy additions also […]
1. Fin .999 Silver Fine silver is the closest metal to the pure element silver. It is marked .999 som indikerer 99.9% renhet. De 0.1% remainder consists of trace elements of insignificant quantity. Fine silver has a more vitreous luster than the bright polish of sterling. It appears grayer and slightly dull. This type […]
The reason sterling silver requires the mixture of other metals is because naturally, rent sølv er mykt. Adding other metals to the silver increases the hardness, making it more suitable and durable for use in jewelry and housewares like silverware. The result of this process also produces that signature silver color: lys, shiny and […]

#1. Rub the jewelry using a soft white cloth. If you find any black marks on the cloth, then you can be sure that it is made of real sterling silver. This is because any air exposure causes real sterling silver to oxidize. This causes them to deteriorate with time, and the reason why […]
You could imagine very easily that if there’s a 20% price jump from a 0.99ct diamond to a 1.00ct diamond, the cutter who loses that 0.01ct trying to make a prettier stone will lose his job. Perhaps with the nicer cut it will only be worth 15% less instead of 20%, but either way, […]
I stress categories, because you might mistakenly believe that prices per carat increase continuously as weight is increased, but this is not the case. Since diamonds are a retail product driven more by emotion than reason, a 0.99ct diamond is worth only about 1% more than a similar diamond weighing 0.98ct. But a 1.00ct […]
Diamonds are all priced per carat. Lets say a 0.50 carat diamond has a price of $1400 per carat. That diamond’s price for the stone would be $1400 * 0.50, eller $700. Eller, let’s say that a 1 carat diamond has a price of $4,100 per carat. This one is easy to calculate — […]
