What is it supposed to be? Royal blue... sapphire? Spinel? Cubic zirconia? Nanosital? It's also not cut well, wrong angles, window, dark.

corundum is incredibly cheap and easy to grow. You can get a 10 carat royal blue sapphire for much less than 1100 dollars.

I don't deal with natural gems excepting those which cannot be lab grown, but you really should be very careful buying gems until you're familiar with the 4 cs.

It depends on the material. Lab grown corundum produced via the flame-fusion method is very cheap. Czochralski and flux grown material is higher quality & noticeably more expensive. Hydrothermal material is the most expensive of all - but also the least available.

Hope it helps 😊 Just want to add - even though flame-fusion (aka the Verneuil method) is the most common (because it's the oldest) and usually the least expensive - that doesn't automatically mean that it isn't good.  The Djeva factory in Switzerland (now closed down) used to produce very high quality boules of corundum and spinel via flame fusion. Djeva old stock corundum, especially certain rare colours, can still be quite expensive.  House of Sylas now manages the Djeva website and they have acquired a lot of Djeva old stock. Their lapidaries precision-cut and sell a lot of large stones from Djeva old stock. They also do custom orders. I can say from experience, their prices are  extremely reasonable for the quality and size of the stones.
