Hi

I was looking at engagement rings on the weekend and the shop assistant tried to sell me a rand diamond ring saying how great they are. Does anyone have any experience with this? Is it just a marketing ploy?

Thanks

I have never heard of the brand. You'd have to show us a specific ring with the specs (grading report, color, clarity,etc.) and price for us to tell you whether it is a good buy or not. If the center stone is not GIA graded, then I would avoid it.

The fact that they are representing that ring as total weight rather than telling you the center stone size is not a good sign.

Hi, Chair

The first (and only) time I viewed any RAND diamonds was about 15 years ago. At the time, they were priced high (comparable to Hearts on Fire diamonds), but I understood at least part of the premium is due to the assurance the South African company seeks to offer -- to those for whom this might matter or be impressive -- re the provenance of each diamond it sells. Click the Provenance header on the home page to see more about the "birth certificates":
http://www.randbrand.com

IIRC I had a very favorable impression of the performance of the several RAND diamonds I had in hand (not as a prospective purchaser, but rather because I was satisfying idle curiosity). But I don't know if that's true across the board, and the faceting wouldn't necessarily appeal to everyone who wants a round diamond.

I'm thinking there should be a GIA report for the RAND (center) stone; if so, can you share that -- and RAND's own certificate for the center stone -- with us?

Is the center stone GIA graded?

A GIA Ex cut .46 F SI2 averages in the $900 (US) range.

A setting like that can be from a few hundred to a couple thousand on a stone that size.

So, bottom line, that ring is about $3700 USD. I think you can get a better quality (or larger) diamond and setting for that price.

I found the following info on the Rand

3-Dimensional Symmetry is the balancing of all the cut elements in a RAND Diamond. It ensures that the table, crown angle, girdle and pavilion are balanced and interact with each other perfectly. Bringing the elements of a RAND Diamond into this precise harmony aligns the light so that the sparkle and brilliance is greater than the sum of its parts.

While perfect 3-Dimensional Symmetry results in exceptional sparkle, this is only possible if the symmetry is achieved with utmost precision. Alter slightly just one of the precisely positioned angles and the light becomes less coherent. To ensure precisely positioned angles RAND utilises a proprietary cutting method called Zero Tolerance.

While it is common knowledge that a diamond’s facets need to be matched in size and shape, it is less commonly understood that the angles of the facets can vary through a small range. In other diamonds this variance allows light to diffuse quickly and dull the look.

Because each RAND Diamond is designed on a 3-D cad/cam computer and polished to its exact blueprint specifications, these variances are not allowed and the diamond is polished to maximize its beauty and sparkle without regard to time and material use.

In fact each RAND Diamond takes an average of four times longer to polish, and only artisans of exceptional skill are able to polish a diamond to its exact blueprint specifications. At RAND we call this process of matching a diamond to its blueprint “Zero Tolerance Precision Cutting.”

RAND’s Zero Tolerance Precision Cut coupled with 3-Dimensional Symmetry results in unsurpassed levels of refraction and reflection producing crisp brilliance fire and sparkle unseen in diamonds that are less precisely cut. This technical perfection, 3-Dimensional Symmetry with Zero Tolerance precision is the platform upon which a RAND Diamond is born.

Ok thanks, so the fact it's a rand diamond won't affect price?
A very tiny bit on a .46 with SI2 clarity. For example, our hearts and arrows (top cut quality) vendors usually don't even include SI2 diamonds in their stock.

Here's a .41 F VS2 ACA from Whiteflash at $1200, and I can tell you, I'd a million times rather have a top cut stone in VS clarity over SI2.
