To add another angle to this after re-reading your first post,I found when I was selling loose diamonds or ready made rings to couples getting engaged,that inevitably they would ask about my diamond and why I chose it etc.When I told them I loved it because its an old-cut and I fell in love with its beauty as for an old cut it does have incredible fire and life,and it has uncharateristically good reflection from the back facets I found it a truly enchanting stone and totally lost my heart to it the very second I laid eyes on it!
This always led to the same question, 'so if your saying old cut,that means its very old right?how exactly old is it?' Yes its old,I would reply but I could'nt say for definate exactly how old,but it is a pre-owned diamond,the girls knee jerk reaction was always so typical it always amused me a little! 'Oh God I would'nt want a secondhand diamond or enagagement ring that someone else has had before me!!!!!!' then after this involuntary outburst they would look mortified and go on to apologise profusely,and in the steady stream of apologies I had to find an opening to say its quite all right,don't worry,its not everyones idea,thats why the trade in new sales is as strong as it is,and there is absolutely nothing to criticise by wanting to own a new diamond and enjoy the totally lux pleasure and experience that it brings in picking and owning a brand new diamond.
So in my experience in selling possibly several hundred engagement rings,very likely more but I am erring to the side of a conservative estimation, is that there is an unfortunate stigma attached to pre-owned diamonds as engagement rings.And despite a couple being strapped for cash,they would always pass over a bigger pre-owned stone for a smaller new one,even though the young lady in front of me really wanted a bigger stone but was disheartened to learn the size she wanted was out of their financial reach at new prices,despite me trying to cut them as keen a deal as I could economically viable as I could for both of us.Even then a new diamond was more preferable to her,even when I offered interest free credit on a bigger new stone, they felt this would reduce their lovely new purchase to just a financial transaction,which I could see to be honest,it would kind of bypass all the romance for them,and I respected that.After all sitting and filling in a form that asks you all kind of personal details down to the measurement of a rats ass in front of a relative stranger,does take the shine off a romantic moment.
So,very much unfortunately for whatever reason the stigma does exist,maybe as Trading Standards over here demands that we disclose these details may perpetuate this somewhat.I know in my time in the jewellery trade and working for extremely high end jewellers to high street chains that customers always chose new over second hand,pretty much whatever thier financial circumstance. So by highlighting the point of pre-owned diamonds being a good buy is not going to damage sale of new stones any time soon. Merely pointing out their existance maybe the answer to some young ladies dream of owning a stone they could'nt otherwise afford,even some of the .20 point diamonds,less than a quarter carat have made some couples I have served wince at the price even when it is a well priced quality little stone in 18 ct gold at less than £350 UK sterling.
I can count on one hand the amount of pre-owned diamond engagement ringsI have sold that are intended as engagement rings on one hand,and so can my husband who was in the trade too,he was in the trade a total of ten years and he sold two.
As for me I sold the grand total of four.
And without revealing too much that again would be very disconcerting and annoying to the retail public I have first hand knowledge of how much new diamonds can be marked up by,and how it can differ from a prestige store to a high street chain,for the same quality.
There I think is the real deception to the buying public, how one place can charge more for the same quality stone than another simply by the name over the door.
But, I have encountered a lot of very savvy ladies who are well aware of this but shop there by choice and the retail experience they get,cost regardless.
And it is this freedom of choice that keeps all aspects of the trade thriving. As one of my contacts very succintly put it,'all diamond sales are valuable at keeping diamond at the top of the gem tree,they keep its desirability to a maximum as one of the most coveted,admired and desirable stones and every lady who wears one whatever its size and provenance keeps advertising this fact,and in return they get a truly beautiful peice of nature that can be enjoyed for generations'.
