A Banjarmasin keris

Yakut are rose cut rock crystal.

Many dealers will try to pass off yakut as intan, and really, the only way I know to tell the difference in a buying situation is by having seen and handled a lot of both stones.

Intan throw a very hard, often blue light. Its a hard, cutting light---if that makes any sense. They have a good brilliance, most yakut have very low brilliance, and they throw a softer, whitish light.

If you examine under, say, a 3X loupe, the edges of the facets in intan will be hard, sharp and clean and the facets will be clean and level; in yakut the edges of the facets will often be bruised, a bit rounded, showing wear.

There is a very, very big difference in value between intan and yakut. Intan are not always low grade diamonds. Intan is the old fashioned rose cut, berlian is the modern brilliant cut. Its the cut that makes the difference in name, not the quality. My wife has some very good 19th century rings set with intan, and the stones are large and without inclusions, of good brilliance, and good colour---but they are still intan, because they are rose cut.

Thanks for sharing, Alan!

That has been more substance contained in a short post than years of hearsay.

Hi Alan,
by rock crystal do you mean good quality clear quartz crystal. My second question is if intan is the cut not the stone, what stones would qualify as intan in the sense of intan as applied to a keris handle or sheath. You have said that rose cut rock crystal is yakut so presumably intan would have to be relatively colorless and harder than rock crystal....diamond, white sapphire and topaz would be my guesses.
regards

Intan are from the same raw material as diamonds, but they are rose cut diamonds, not brilliant cut diamonds. Brilliant cut diamonds are called berlian, rose cut diamonds are called intan.

Intan have the same range of colour as any other diamond, and can be yellowish, or blueish, some even seem to be almost black. But as I said previously, they are always quite brilliant and give off a very hard, cutting light.

Intan are not something that is exclusive to keris culture. It is a type of diamond, it is found in all sorts of jewellery, and it lends its name to shops and other businesses.

Sorry I didn't make this clear before, I was homing in on the quality question. Intan is not an indicator of quality, it is an indicator of cut.

I do not know if quartz crystal is the same as rock crystal. It probably is, because at lapidary shows we see big lumps of clear quartz, and smokey quartz and rose quartz. I only know yakut as rock crystal, and it is the same material that is used in Indo Persian rock crystal dagger hilts.

Nice keris with all the local details!

What's the size of it?
Is it smaller than a regular bugis keris?

BluErf,

You must be traveling a lot for your collection or is it a lot of keris traveling to your collection?

If the second is the case, please share the charm/spell

.

Can we please see the pesi when possible?

Hi all,

Sorry, was busy for past few days. Ok, I've got the pic here. Pardon me - I didn't unwrap the nylon thread around the peksi because I thought it was rather well-done and packed-in to try to unravel.

Anyhow, you can see the base and the tip, and get an idea of how tall and thin it is. The nylon thread is quite thick.

The keris blade is 11.7in, which makes it more or less the same size as a standard Bugis keris. The peksi is more than 2in tall.

To Tunggulametung - I haven't been travelling much.

But I don't know any useful spells too...

maybe it is because of a great keris that I "sacrificed" recently that brought these other rare kerises to me...
