The platinum used in platinum engagement rings is to a large extent more rare than gold and perhaps this is why it costs 4x as much as yellow gold and 2x as much as white gold. different gold, platinum is used in about its pure form in jewelry. Platinum’s purity is indicated by a 3 digit number which ought to be marked on the band. For example, If your band is marked “950 platinum”, the band is 95% clean platinum with alloys constituting 5% of the ring. Most platinum is mine in Russia and South Africa.
One of the slighter known facts about platinum is that it is hypo-allergenic and will not aggravate your skin. My friend, who recently got married, was argumentative to me about her white-gold engagement and wedding bands, which were creation her finger itch. As a result, she is only able to wear it every few days and may have to get the within of it plated in platinum or another metal. What a hassle.
Another helpful thing about platinum is that it is low continuance. Platinum will not rust, tarnish, or require frequent trips to the jewelry repair store. My white-gold engagement ring is not assembly my finger itch but it lost is luster a number of months ago. When I used some self-tanner, it seemed to erode the plating informative a yellow gold color underside. I eventually need to take it in to get it re-rhodium-plated. In other words, I’m a low maintenance girl sportin’ a high maintenance ring.
