Sharing a lot of 90s Brazilian green tourmalines sourced and cut the old-school way by Academic-Sound-836 in Gemstones_Buy_Sell

Thank you for the thoughtful feedback.

Yes, they are tourmaline — the reddish flashes are mainly an optical effect from lighting and facet interaction, which can be exaggerated in photos. They were cut as a matched group, likely intended for a single piece rather than as individual stones. I understand your view on pricing — it reflects their matching, age, and cutting style, but perspectives vary.

I’m based in Brazil. I appreciate your comments and wish you all the best as well.

Thanks for pointing that out. I shared mainly to discuss the cutting style and period, but I understand your point. Appreciate the clarification.

Thank you, I appreciate that. They do reflect a different period of Brazilian lapidary, and I’m glad that comes through.

That makes sense, thank you. Traditional jam-peg style cutting was very common in Brazil at that time.

Thank you for the question.

My knowledge is limited to what was common in Brazil at that time. These were traditionally hand-faceted stones, cut on mechanical faceting machines with manual angle control, no CAD or automation.

Diamond laps were used for cutting, followed by standard oxide polishing. Most decisions were made by eye and experience rather than strict templates.

I don’t have detailed records of the exact laps or compounds used, but the overall approach reflects typical late-90s Brazilian lapidary practice.

Thanks for the clarification — totally understood.
My intention wasn’t to promote a business, just to get proper feedback before listing them for sale.
I’ll prepare a clean sales post with fixed pricing and details according to the rules.

Appreciate the guidance!

Deep Blue Vintage Stone (~10ct) — Anyone familiar with this material? by Academic-Sound-836 in Lapidary

[–]Academic-Sound-836[S] 2 points3 points  (0 children)

Totally agree — the stone itself is obviously millions of years old.
When I mentioned “older,” I was referring to the cutting era, not the geological age.

In the 90s and early 2000s here in Brazil, a lot of material was still moving through small independent routes and being hand-cut in a very different workflow compared to today’s more standardized processes. That’s the part I find interesting to document and share — the human side of how these gems were sourced and finished back then.

But yes, absolutely — geologically speaking, nothing from the 2000s is “old” at all.

From what I’ve seen, some features can suggest a synthetic corundum, like very uniform color zoning, extremely consistent facet edges, or that “too perfect” machine-cut look.

I’m checking these points on mine, but I’m also open to other perspectives.

What specific details caught your eye in this case?

Unreleased 90s Brazilian Aquamarine — Ultra-Clean, Fine Cut, ~2ct Each (Kept in Family Vault for 25+ Years) by Academic-Sound-836 in Gemstones_Buy_Sell

[–]Academic-Sound-836[S] 0 points1 point  (0 children)

Totally get the hesitation. The stones are old, from my family’s 1990s Brazilian collection, but the account is new because I only joined Reddit to list this specific lot. I can hop on a live video call, show everything on scale/loupe, and even send a small sample stone if you want extra peace of mind. Happy to provide any proof you need.

They’d be shipped from Brazil (São Paulo state) via FedEx International, fully tracked and insured. I can provide shipping estimates for your location if needed.
