according to Heide Rezepa-Zabel, who is a professional gemstone evaluator and the expert who evaluated this gem, this is not true. she said: "Santa Maria is a color designation and a trade mark. this singular color (put into bold by me) was so rare that it was first discovered in the Santa Maria de Itabira mine in Menas Gerais in the 1920s. ... these stones were found over a period of about 25 years". here a link to a website which says the same: here an excerpt from this article describing the main characteristics of a Santa Maria gemstone: The 4 Cs of the Santa Maria Aquamarine Gemstone Most gemstones are assessed using the 4 Cs: color, clarity, cut, and carat. Color is of utmost importance for colored gemstones like aquamarine stones. Therefore, they are first categorized by the quality and type of color that they display, such as a Santa Maria blue. Clarity refers to the imperfections or the lack thereof, within a stone. For colorless stones it is ideal to be as clear and void of inclusions as possible. While it is still of great significance to showcase impressive clarity, color gemstones, particularly beryl, generally possess some sort of imperfection. Having said that, Santa Maria aquamarine gemstones are known for being ‘eye clean,’ meaning, inclusions cannot be detected by the unaided eye. In terms of cut, aquamarine stones need to be cut with sharp angles and symmetric patterns because of their reflective nature. This is why stones with a high clarity can still appear dull if they have a poor cut. Lastly, it is difficult to find a Santa Maria aquamarine in large carat sizes. Half a carat is about the largest size for an average stone. However, LEIBISH is fortunate enough to possess a 1.23-carat Santa Maria oval-shaped aquamarine gemstone. this article mentions that aquamarines of this color are now called "Santa Maria" regardless of their origin; Heide Rezepa-Zabel mentioned this too. but from the way the socket was crafted she could date it into the 1920s and was extremely certain that this gem is really from the original Santa Maria mine. I uploaded her expertise; the video is of course in German. the expertise stated that this gemstone was top in all 4 regards: color, clarity, cut and carat. of course there are offerings of so-called Santa Maria aquamarines in the internet, but only very few of those are real ones

Blue pectolite is absolutely the most beautiful of the colours it can be found in, and absolutely looks more “aquarmarine” than aquamarine. In the UK, you’re more likely to come across pectolite that is pink, as Scotland is “well known” for its pink pectolite - but it’s nothing on the colouration of larimar.

^ Glad that you liked them!
And oh, larimar is more "aquamarine" than aquamarine. |

I like both this agate and the “banana cream” you posted earlier. Agate is just cool.

I've just stumbled across this one on Facebook. Agate, I guess. They called it "banana cream". It is from Turkey. Hmm, another kind of "Turkish delight" that looks delicious, indeed.

Possibly. I would have to take your word on that, but I don’t disbelieve you. I know it as celestine, but that is possibly because I worked at a jewellers, and celestine is a “nicer” name. I had never heard it called celestite before, so perhaps it is a geographical thing as to which name people call it by. Similar, I guess to aluminium and aluminum (which I just had a bloody hard time typing, as it kept being auto-corrected). It’s very pretty, regardless. |

Wow! That’s gorgeous! I have never seen any celestine, before. Well, at least, not as a stone. I would guess I’ve seen rather a lot of it over the years as fireworks, though! 😄 Edited by nick_h_nz - June 27 2022 at 12:18 |

^ Oh, OK. We are friends again Nick. Your obstinacy shattered my walls.
No, but I Googled those emeralds, quite an oddball of a gemstone, I must say. And, this is another stunning blue gemstone: Celestine |

It’s weird, because my favourite colour has always been blue, but when it comes to beryl, my favourite stone is not aquamarine but morganite. It’s something quite peculiar to beryl, too, I think, ecause I like blue sapphires, but don’t really like pink ones. And yet, I can’t deny I really quite like morganite, while not caring so much about aquamarine. 🤔🤷🏻♂️
Since we’re talking beryl, have you seen a trapiche emerald, Ozgur? I figure if you like star sapphires, you possibly like trapiche emeralds? I’ve seen plenty of star sapphires, but I’ve never seen a trapiche emerald. (Obviously they are considerably rarer than star sapphires, so quite possibly you’ve not either - but given your interest, maybe you have?) |

I preferred to put gemstones like "stones", though some of them are crystals.
As Jeanine pointed ouy, normally too light or too dark coloured aquamarines are generally cheaper. But who cares? I love light blue aquamarine stones! |

Actually, the stones posted by Ozgur could well be, and probably are, “Santa Maria” aquamarine. Given they have not been polished and faceted, it is difficult to tell what colour they might be as a “finished” gemstone. Also, Santa Maria aquamarine can still have quite a range of hue and tone, and can mean something different depending on how it is used. You need only Google image search for Santa Marine aquamarine, and I am sure you will see quite a variation in colour. All it really means is that blue is more predominant than green, so the stone will be noticeably more blue, and described as blue, rather than blue-green. But there are still plenty of tones and hues of blue that are not blue-green,

^ Yes, the onyx stones I put there are not "ideal" either.
Even I have a pendant with a higher quality aquamarine stone than those. Edited by Archisorcerus - June 27 2022 at 11:17 |

the aquamarines you showed don't have a good color. in the XXL- version of the German TV-show "Bares für Rares" ("Cash for Rarities") from June 22nd this year a top-quality aquamarine in the legendary "Santa Maria" color variation (which is considered to be the best) having 35 carats was sold for €21000 Edited by BaldJean - June 27 2022 at 11:11 |

If the Guinness World Records site is to be believed, and they do have a reputation for checking and rechecking fairly vigorously before agreeing to include a record, then: |
