PS Diamond Price Chart

[oranges]

Hi Everyone,
I was looking at the PS Diamond Price Chart (located here: https://www.pricescope.com/diamond-prices/diamond-prices-chart/) and I'm really confused. The price of 1-2 carat diamonds (the red line) is showing that prices are lower NOW than they were at any other date from 2007-present times. How is this possible? Diamond prices have rose like crazy in the past year. It definitely does not seem to be correct. Maybe I am not understanding how to interpret this graph. Any help would be appreciated!!!

I am by no means an expert, but perhaps fewer people are able to afford diamonds in the 1-2 ct ranges and this is the reason for the decline in price?

Assuming the chart is an annualized chart of month to month changes, I think the chart shows % change, not absolute prices. Prices are probably higher now than in 2007, but the % price change has decreased in recent months?

I think, more than anything, it shows a dramatic decrease in the average quality (cut-quality) of the diamonds in the PS-database. One could wonder about causes and consequences.

Live long,

Paul, I don't see where it says the cut quality changed?

Hi,
According to Tiffany diamonds have fallen in price 16% since August 2011. They lost money the last quarter because people stopped buying diaonds because of the price increases. No one has mentioned this on PS.

That graph does not show average prices.

It shows percentage change.

At present, the percentage change is about -8%. So prices dropped from last month to this month. That says nothing abot how prices now compare to 2007.

Thank you for your responses ! Although I am still confused. So the graph show a % change from the last time that the graph was updated? Maybe I'm having a blonde moment, but I still really do not understand how to interpret this chart. Either way, the 1-2 carat stones didn't experience as great as a price hike (aka percent change) than stones of other weights? Why is this ? I feel so stupid.

Can someone give me a PS Diamond Price Chart for Dummies guide? Please?

Each bullet point on that chart represents the difference in price from the prior month only. The bullet point does not represent a $$ amount - only the change relevant from past month's prices. Therefore, the points can only provide you with the change from past month and not at any other point on the chart.

oranges, I think your first impressions are correct. In my memory the red line for 1-2 ct looks nothing like this last month. You can also see that the red line for 1-2 ct in Google's cached versions for earlier months look nothing like the current chart.

I think the data/formula feed simply got messed up for this month's red line for 1-2 ct and hopefully PS corrects it soon. As far as I'm aware the chart tracks cumulative percent changes since December 2007.

ETA: There's absolutely no way that the chart tracks month to month change. Any idea how much a 0.5-1 ct would be now if it increased in price 20%+ per month 8 months in a row?

ADMIN please explain!

I don't think it reflects monthly change against the 2007 benchmark, but it also can't be month to month. Must be a glitch.

Ok-all fixed. Thanks for pointing it out. We appreciate it! We had a small error in one of the data points that threw off the chart.

Thank you for all of the clarification everyone-- that chart just didn't look right. I still don't understand exactly what the graph is showing. It seems like there are conflicting ideas on that matter. Does anyone know for sure?

I still don't understand exactly what the graph is showing.

It's percentage change since 12/3/2007 (says right in the title of the chart). And you'll notice everything starts at "0%" on that date. It's all relative to that initial date/month.

Yes, now it makes sense. We are tracking how things have changes since the start date. So today prices 0.00 to 0.50ct diamonds are approximately 8% higher than they were in December 2007. At peak, in August 2011, those same size stones were 20% higher than December 2011.

That is correct!

Awesome. So I was reading it correctly originally. Good to know. I appreciate all of your help and I'm glad that the chart is fixed! It is a very useful tool. Hopefully this downward trend will continue!!!!
