Re: help with alexandrite engagement ring

That one has a very weak colour change so not a great specimen - although the cut looks nice.

Try asking David at www.multicolour.com to see if he has anything that might fit your budget/parameters

Hahahaha - always late to the party! I'll just sit here with my bottle of wine and get quietly drunk then! I wondered what the other ring was! :wall:

Re: (Mostly) finished product!

Have a look where I've added the red line. Ask your jeweller to drop all the stones to this level. Currently you can't see the culet of any of the stones so they can be dropped further down without any impact. The sides of the shank, where they sweep upwards to the head of the ring is too thick whic...

Re: Risks involved in setting a sapphire into a gold setting

Are you willing to take the risk? Even the most experienced of setters can have a mishap even with a stone with no issues. If you're worried and would be left seriously out of pocket, opt for the more expensive route. I once had a very very experienced setter, chip a diamond quite badly. It happens.

Re: Red spinel opinions

I tried to be really diplomatic but it looks like you want the hard facts. :knockout: On my monitor, the spinel does not look like a true red. It is a bit dark in tone, has some areas of extinction and is sort of brownish, given that it is photographed at almost the best lighting condition (shaded ...

Re: Unheated pink sapphire...

Don't get too hung up on the untreated part. Colour is more important than plain heat although diffusion is a different matter altogether. If you are looking for untreated, that's okay too. If you want a spinel with better colour or unheated pink sapphire with good colour, the budget will probably ...

I agree with Chrono but I'd mention something else. In the top picture, your photo shows a tilt window - this is something that many many gemstones have and it's not something to worry about. Your second photo is really the only one that is taken with the photo straight onto the camera and it doesn'...

Re: Help me establish the scam / the deal here

I highly suspect their photos have been enhanced. For example an AA grade Tanzanite will (if it's graded correctly) be a very wishy washy blue and not the gorgeous deep blue you see in the photos. In fact, if you look at the bracelet that's graded AA and then the rings you'll see a significant diffe...

Re: Color enhanced diamond changes colors as a function of l

Your stone is intriguing because it doesn't react like any diamond (irradiated or otherwise that I've ever seen). Diamonds with fluoresence can appear to be different colours (ie white at times yellow or blue at others) but even chameleon diamonds don't change like this. What your stone looks like i...

Re: FCD as investment 2.

Kenny summed it up beautifully. It doesn't matter what the market says or does - the issue is, will anybody buy your stone at a later date. The answer is probably no unless it's a steal of a deal.

Re: Is this an emerald or something else?

Based on your photo, if I had to guess, I'd say that was an Emerald. However, as Chrono has already said there's no way to be sure. It does look very typical of the Emerald ring you see on shopping channels (The Jewellery Channel in the UK in case you want to look on their website).

Re: (Cartier inspired) Cuprian Ring

May I make a suggestion please Chrono?

Rather than curve the petals down, it'd be a little more organic to either (a) curl them gently upwards or (b) have them so the edges curl up and down (a little wavy).

Re: Can cabochon be mounted on a prong setting plus other ad

Most settings have a V shaped basket and a stone sits inside the V (almost touching the bottom at the pointed bit). Most cabochons have a flat bottom so they would be suspended above the V. This can look odd (depending on the setting) and it could make the stone slightly unstable if the prongs loose...

Re: Paraiba Tourmaline Question

If it was as easy as testing for copper at home then why would people send anything to a lab? To test for copper in a stone it takes an incredibly expensive machine. It wouldn't have been designed if we could test at home. This is not just about does it have copper or not. The chemical make up of a ...

Re: Amber Rose Gold Ring with Stones?

I've never seen an Amber set in rose gold and I think the reason is that, unless the Amber is more red in tone, the orange of a "normal" amber will clash with the rose gold. Out of interest, I've just done a Google search and there aren't many examples. What I did find seemed to indicate t...

Re: 5-stone sapphire trellis ring project with Michael E

It's lovely and I'm so glad you're pleased with it.

I didn't chime in earlier because I actually love having trellis creating Vs so I was struggling with the U shaped concept as my brain wasn't working that way. It certainly does look very nice indeed and I'm sure you'll enjoy wearing it.

Re: Help me choose a tourmaline from the Master Cut Gems sal

I'm going to disagree with my learned friends above and say I really do like the second stone. It looks like it has lightning flashes of rose colour inside the stone and I also like that the lines are wavy and not straight. The cutting gives the stone an interesting personality.
