Compare up to four fragrances

Kristal gets the broad shape of Kirkè right almost immediately. Passion fruit and peach dominate the opening, with pear and dark berries filling the gaps. Smelled in the air, that dense tropical fruit cloud is close enough to make the reference obvious without knowing the bottle.
Where Kristal gives itself away is texture. Kirkè has a peculiar dry, sandy quality underneath the fruit that stops the sweetness from feeling completely glossy. Kristal is softer, sweeter and more shampoo-like, with heliotrope and vanilla becoming noticeably powdery as it dries. The musk also feels less refined when smelled directly from skin.
There is some Erba Pura overlap here because both fragrances live in the same saturated fruit-and-musk neighborhood, and a few wearers understandably make that connection. Still, the note structure and overall impression point more convincingly toward Kirkè. It lacks the original's polish, but for the price it reproduces the loud fruity aura surprisingly well.
