Welcome to Tnet.

Sadly, the certification laboratory KGCL does not have a good reputation in gemology circles, as evidenced by this from the website of JIBNA (a leading jewelry insurer in the US):

JIBNA also reports: “One consumer commented: ‘I found an online forum with some absurdly good deals. They offer a certificate by KGCL that looks a bit sketchy, because a google search turns up nothing for the company. Maybe KGCL is a company in India that is deep in the mines, and has no time for a website? If so then it could be true, and a very good deal.’ Hope springs eternal, as does gullibility.” Others are reporting that they can find no website for KGCL, nor a valid mail address.

The ’certificates’ appear to come from an eBay trader called ‘gems-india’, available for $15 for stones purchased from them:

Whatever, the mineralogical determination of the stones you are showing might be (in all 3 of your posts) they don’t appear to be of ‘gem’ quality in my opinion, which makes it difficult to put a true value to them.

+1. Faceting/polishing a stone doesn't make it a gem.

Thank you for your input. I do realise the 3 stones I put up have flaws and are not jewellery grade. But they are still beautiful gemstones in real life.

Beauty is always in the eye of the beholder. 😍

Possibly get an initial quote from a reputable jeweler. That’s a place to start, not necessarily the top $ option.

It's been a while since I've dealt with gemstones. So I just googled 1000 ct ruby, and found one on Amazon in pear shape for $61 US. I imagine yours would go for half that or less. The attribution card is probably to catch the buyers eye, making selling it easier to lure the unaware buyer.

In looking through certifications of gem stones all the companies will have a certificate record papers as this example.
Not a card as been shown by the OP.

In rubies, as in most gemstones, clarity (lack of flaws) and color intensity affect the price. A clear, blood or pigeon blood-colored stone is kind of a benchmark for rubies. Of course, on “cut stones” the faceting is very important as far as difficulty of cut, how the facets reflect light and symmetry.👍🏼

 

[unclemac]

in other words, for your ruby to be valuable, it needs to look like clear red glass.

 

[galenrog]

That stone was very badly cut. Due to all the inclusions, and other characteristics, it should have cut as a standard cabochon, with a rounded, polished face, rather than faceted.

Time for more coffee.

I bought some of these from the muzo mines..emeralds years ago. They were huge. Cheap and fun investment.
You get serious.... you go for eye clear.
Welcome to the forum.

Unfortunately they are a grade just above driveway gravel, it’s marketing.

They qualify but are the absolute lowest grade possible. Similar companies used to send them out for free, then a week or so later a catalog would arrive with all sorts of settings to mount your free stone! For real nice goods (from a friend of mine for 42 years): Skybolt trading LLC.

I was going to go down the road others went - I've done [only a little] Safire mining. In the course of that, I looked up info on it and learned rubies are just red Safires they, arbitrarily, decided to call rubies. I have green ones, blue ones, white, yellow and red ones. All are clear.

Safires with the brighter colors are made that way by heating them, under controlled circumstances.

As to emeralds, they are soft, compared to many stones, so people are advised to take them off when doing chores. Too, many have a coating and detergents can soften the protective coating.

All the emeralds I've seen are clear, like the Safires.

As to the value of your stones, it depends on what someone will pay. A lot of stones can be disappointing, for their appraisal value, but many are worth a bit too.

Yes, sapphires and Rubies are both corundum.

Hmmm... And I always thought sapphires are just blue rubies... Go figure! 🤦🏼‍♂️
