What the trade is actually asking.
Ask what a stone is worth and you will be told it depends, which is true and useless. The GV Price Guide will record what stones are being asked for, by stone, size band and stated treatment, compiled from dated dealer catalogues and published auction results. Free to read, and it stays free.
How it will be built
Asking prices, named as such
What a dealer publishes as their price is an asking price, not a valuation and not what the stone changed hands for. The guide will say so on every page rather than let the distinction blur.
Every figure carries its date
A price without a date is not information. Each observation is stamped with the day it was read and the catalogue it came from, shown as plainly as the number itself.
Treatment stated, or recorded as unstated
An unheated stone and a heated one are different goods at different money. Where a catalogue does not say, the guide records that it did not say, because the silence is itself worth knowing.
Thin data suppressed, not smoothed
Where too few observations exist to say anything honest, the cell will be left empty. An invented average is worse than a gap.
What it will not be
- 01An appraisal or valuation of any individual stone. We verify dealers, not stones.
- 02Investment advice. Gemstones are not a regulated investment and we do not present them as one.
- 03Purchasable. No dealer can pay to move a figure, or to keep one out.

You will receive the first tables with the methodology note, and nothing else.
Questions, answered
Is this a valuation?
No. It records what dealers are asking, on a date, from a named catalogue. What a stone is worth to you depends on the stone in front of you, its report and what you are buying it for. For an appraisal, use a qualified valuer.
Why is it free when others charge?
Because a price reference behind a paywall is read by fewer people than it should be, and because the register already collects the underlying observations as part of its work. The cost is the collection, which we are doing anyway.
How current will it be?
Each figure shows the date it was observed. Stale observations are not quietly refreshed to look current; they age visibly, and where a band has not been re-observed recently the guide says so.
Can I use it to negotiate?
That is roughly the point. Knowing the asking range for a stated treatment and size band tells you whether a quote sits inside the market or outside it. It will not tell you whether the particular stone is good, which is what the report and your own eyes are for.
