How Do I Light Up My Jewelry?

12/17/2007 12:35 AM

I am looking for a small light that would fit behind the gemstone of a ring or a pendant. I would like for it to last at least 3 hours and not get to hot. The power source and light would need to be small enough to hide behind a 4 to 5 carat stone.

Consider

  • a sub-miniature light-emitting diode
  • "beta" lights (β-radiation emitter)
  • fibre-optics.

there is no small enough power source + light to hide behind a 5 carat stone, however a monofilament line can be used as a light pipe and you can pipe the light from a hidden pack a few feet to the stone.

I think we can help you with that...

We deal in LED to a large degree, and I also have a friend that specializes in very small LED Lighting...

Actually, we are presently designing certain pcs of higher end womens clothes with very tiny led, and our theme is classy, NOT flashy..

Incidentally, LED of the proper color, (depending on the color of your diamond), will Greatly enhance your stone.

I also have a friend who is a certified Jeweler, surely we could help you.

Thanks

Don

Hi Guest.

As a Gemmologist I have to tell you that gemstones have been fashioned in such a way as that the light coming from the front or top of the stone exhibits maximum brilliance and colour.

The reason this occurs is that any light shining on the top of the stone is totally reflected from the back or bottom of the stone. Take a diamond or any other transparent stone and look at a light scource from the back of the stone, it will appear dull and lifeless.

When cutting gemstones you have to take into account it's refractive index, as every different type of gemstone has a different RI, the Pavilion (back of the stone) has to be cut accordingly to allow for total internal reflection, ie different angles.

So for best results the light scource must come from the front of the stone!!!

Spencer.

I'll second that. I've been cutting since I was 10 (don't ask how long) and a light below the stone is going to reflect most of the light to the sides and do a good job of lighting the setting. Don't get me wrong, some will get through into the stone. But I'm not sure how much of an effect you're going to get.

Now if you put a small facet, like a reverse table, on the culet and then pressed that flat spot onto a SMD LED then the effect would be rather dramatic. But the gem industry wouldn't be very considerate of the value of your stone, so you're going to whack a bunch of $$$ off the price if you try this.

But does he want to do this to expensive jewelry? most probably not, just cheap stuff to make an impact.....I would certainly not want to touch anything expensive in this manner.....its hardly going to improve the value is it?

While it is true that there has been a lot of effort to make gems reflect ambient light, even a small amount of an exclusive light shining at even the worst angle will set the gem on "fire".

Here is a link to a website with garrish flashing led rings for sale for under a dollar .

I am sure that will be impressive. If you want to be on the leading edge there is a battery technology that is making strides recently. Silicon nano threads. Supposed to be 20 times better than lithium. You couple that with some flexible OLED strips and you have some techno-geek jewlery anyone could love

Along with all of the previous commentary about the nature of the stones and how they are faceted, keep in mind that it is the setting (whether ring or pendant) that will require modification to accomodate the light source and even possibly the power source. I doubt you'll find an off-the-shelf ring or necklace that will be immediately usable. There will likely be substantial work needing done, and a new design may actually be easier to pull off.

FO Better known as fiber optics with a remote light source preferably quartz incandescent. FO can be had in a very small diameter without side light emmission and very little heat transmitted to the end of the fiber.

HI, You can use a miniature LED(ultra bright white) with a tiny buttencell, the total size of the duo will perfectly fit behind your jewellery.

I saw a jewerly designer piece in (Healdsburg?) California this summer on a wine tasting trip. It seemed to be a battery clasp with tiny silver wires going to a single colored stone that had a smd led inside.The switch was the clasp and the effect was a warm red glow of the single stone. It caught my eye across the room. Hope this helps.
