This is my second Lab diamond from Diyona and like my first order I am extremely satisfied. This was a Quick Ship Diamond. I purchased it last Friday, April 24, it was shipped 3 business days later and arrived today, 1 week after ordering.

It is a 2.4 carat, E color, VVS2 and HPHT. It was $305.16 plus tax and because I'd been watching it, it dropped in price twice by small amounts over 10 days.

I compared Diyona, Alturadiamonds and Aurelinne in a previous post and someone brought Carbon Sparkle to my attention.

I have 9 diamonds from Aurelinne and returned a 10th. Return process was completely free, painless and the slowest part was the diamond itself crossing the country by USPS. Aurelinne has an excellent 30 day free return from after you receive the diamond. This is one diamond in a 60 day period. But unless you have a 15% off code, Aurelinne is now more expensive than the other 3 vendors. Not all Aurelinne orders are free shipping. 

Carbon Sparkle, who I have not used yet, has the same search engine as Aurelinne, the same free return policy, but states 1 free return in 90 days and the site clearly states that free shipping is on purchases over $200. I have tried it out over and over and Carbon Sparkle's diamonds are exactly 15% less in price than Aurelinne, no code needed. They've also improved their search engine to cover more shapes. 

I have an OEC on order from AlturaDiamonds and because Diyona could not get it for me, my 10% off made Altura cheaper than Aurelinne or Carbon Sparkle. When it comes to returns and refunds I would check Altura's website or write for clarification, because Altura's return policy seems to be changing. Kind of hidden under "refunds" was a statement that if you bought your diamond with a discount or promo code, the diamond was NOT returnable. I used that 10% promo code, but I can no longer find that statement under refunds. As far as returns , one section says 30 days, another says 25 and originally it said 30 days from purchase, not from when you received it. With a 10% off code Altura is cheaper than Carbon and with no promo codes for either Altura or Aurelinne, Altura is cheaper than Aurelinne, but if being able to return a diamond is important to you , you need to carefully read the return policy on each site you consider. Also YOU must pay postage to return a diamond to Altura.

Diyona may not have colored diamonds yet, told me they could not get me a OEC I ended up buying from Altura, but Diyona beats the other 3 vendors for price and service. This second purchase came very quickly. This exact diamond was $1266 on Ritani and on sale for $1303 on Brilliance. I have not found anyone yet to beat Diyona's prices. Yes, their search engine is lame, but go to a site with a better search engine, get some IGI numbers and see if Diyona has them. Diyona has the same free 30 day return policy, they pay shipping.

Just for quick comparison, the same 2 carat E, VVS2 HPHT diamond on all 4 sites

  
Aurelinne, $373 , 10% off $335.70, 15% off $317.05

Carbon Sparkle $317

Alturadiamonds $331, 10% off $297.90

Diyona (the clear winner) $255.66 plus tax.
