I’ve had my forever brilliant moissanite for 8 or 9 years. It did develops a oil slick after 5 years. I took it to my jewler and he polished it off. If your worried about too much rainbow sparkle, I suggest getting a hearts and arrows cut. Supposedly, this cut minimizes the rainbow flashes. Also if your worried about a plasticy look to your stone, I suggest getting a near colorless stone. It’ll have slightly more color and may look more realistic. What size is your finger? If its under size 5, a 1.5ct stone will look wonderful on a smaller finger. Size 7 and above, a 2ct stone wouldn’t look too big, but proportional to a larger finger size. I’m a size 8 and my moissanite is 2.5cts. But I like big bling. Here’s a picture of my forever brilliant moissanite for reference:

Regarding the oil slick, I’ve gotten it like maybe twice on my ring? And both times, I didn’t even have to bring it to a professional jeweler — a silver polishing cloth takes it off in about 30 seconds! 🙂 

I have a moissanite but unfortunately am not very helpful with your other questions haha I don’t know the brand of mine, and I’ve never felt like mine had a plastic-y look. But I hope that polishing cloth tip helps!!

cinnarum :  I love my moissanite, though I haven’t had it very long. If you aren’t thrilled with the C and C moissanite, shop around! These days there are several brands and “no name” brands of moissanite, and they all look a little different. There are a ton of threads on the site about some of the newer types. 
I have a MoCo “house brand” (no not really branded) moissy, and I don’t find it looks plastic-y at all and is super sparkly and bright.

cinnarum lui If you lke maximum sparkle, I wouldn’t go with hearts and arrows. It’s made to minimize the rainbow sparkle. Go with a regular round brilliant cut. If your happy with a 1.75ct, I’d go with a 1.5ct. The difference is minimal. Do understand that shrinkage is a real phenomenon. I hope you enjoy your moissanite as much as I do. Good luck

I picked Fire and Brilliance for my stone.  And have never looked back after having it nearly 2 years.  I usually just use soap and water to clean the stone.

cinnarum :  I am absolutely thrilled with my moissy!! I have a 1.5ct hearts & arrows round, GH color and she is a beauty!  I have not noticed it looking plasticky or “fake” at all.  It is seriously stunning.  I got mine through one of the chinese vendors, so I can’t speak for the C&C warranty.  But my ring is insured through Jeweler’s Mutual, so if I ever need a replacement for whatever reason, I will be set.

I haven’t experience the oil slick, but I have heard it is easily removed with a polishing cloth! If you contact C&C, they will send you a sunshine cloth for free! It is a “sample” size but it is plenty big to do the job.  I use mine just to give my ring a good polishing every so often, cause it makes it so shiny and pretty. Go with moissy! It is wonderful!!

I have a 7.5mm/1.5ct standard round brilliant cut, MoCo’s brand of stone. I LOVE it. I have never noticed any plastickiness, and I love the disco ball effect it has. I have yet to experience the oil slick phenomenon.

But I suggest going with an actual jewelry insurance policy and not just getting a rider on your homeowner’s insurance. I use Jeweler’s Mutual, and I highly recommend them. It covers loss, theft, travel, accidental damage, wear and tear, basically anything short of intentional damage, whereas oftentimes a rider only covers theft.

I have a 6.5 mm C&C H&A near colorless moissanite, and just had a Lightbox lab diamond set in basically the same setting. The diamond is 7/8 carat, it measures about 6mm. I previously had a 6mm moissy in the ring, which I had the jeweler swap out and set in the pendant. Here’s both, side by side. The moissanite is larger, on top.

I have an antique cushion cut 1.7DEW moissy and I love it. It’s an e/f colour. C & C

I have a diamond, a white sapphire and now a moissy. Definitely more sparkly and has more rainbows than the other two rings. But I really love the look! 

No issues with oil slick. My warranty is with the jeweller.
